Most developers either overcomplicate email with expensive services they don’t need, or underestimate it with DIY servers that land every message in spam. Learn when to use your own SMTP server versus paid email services based on volume, cost, and deliverability.
Most developers either overcomplicate email with expensive services they don’t need, or underestimate it with DIY servers that land every message in spam. Here’s how to actually choose.
You need to send email from your application. Password resets, order confirmations, notifications – basic infrastructure that every app requires. The question is: do you configure your own SMTP server, or pay a transactional email service?
Stack Overflow is full of developers arguing both sides. “Just use SendGrid” versus “Why pay $50/month when SMTP is free?” Nobody explains when each actually makes sense. Blog posts from email service companies obviously push their product. Hosting providers claim their SMTP is all you need. Everyone has an agenda.
Here’s what actually matters: cost structure, deliverability requirements, volume, technical complexity, and control. Sometimes your hosting provider’s SMTP is perfect. Sometimes you need a dedicated email service. Sometimes you need both.
This guide cuts through the marketing bullshit. You’ll learn what email services actually provide beyond basic SMTP, when their cost is justified versus wasteful, how deliverability really works at scale, where DIY SMTP fails hard, and which approach fits your specific use case.
No affiliate links. No sponsored recommendations. Just the technical reality of email infrastructure in 2025.
SendGrid, Mailgun, Amazon SES, Postmark – they all offer “transactional email” services. But what does that actually mean? What are you paying for that your hosting provider’s SMTP doesn’t give you?
The biggest value proposition is deliverability infrastructure. Email services maintain relationships with major ISPs. They have dedicated IPs with established sender reputation. They monitor blacklists and handle delisting. They manage feedback loops with Gmail, Outlook, and Yahoo.
When you send through Mailgun, you’re leveraging their sender reputation. Gmail trusts Mailgun’s IPs because Mailgun actively manages abuse. If one customer sends spam, Mailgun shuts them down before it damages the shared IP pools.
Compare this to your hosting provider’s SMTP. You’re sharing IPs with hundreds of other customers. If one sends spam, your deliverability suffers. Your hosting provider probably doesn’t monitor blacklists proactively. They might not even notice until customers complain.
According to Return Path’s 2023 Deliverability Benchmark Report, the average inbox placement rate is 85%. But that number varies wildly based on sender reputation. Established email services consistently achieve 95%+ inbox rates because they invest heavily in infrastructure.
Email services provide detailed analytics that basic SMTP doesn’t. You can track delivery rates, open rates, click rates, bounce types, spam complaints, and geographic data. You get real-time webhooks when emails are delivered, opened, clicked, or bounced.
With basic SMTP, you send the email and hope it arrives. If it bounces, you might get a bounce message hours later (if you’re lucky). If it goes to spam, you never know unless the recipient tells you.
Most email services are designed API-first. Instead of configuring SMTP credentials and constructing MIME messages, you make HTTP requests with JSON payloads. This is cleaner for modern applications.
For example, Mailgun’s API lets you send email like this:
POST https://api.mailgun.net/v3/domain.com/messages
{
“from”: “[email protected]”,
“to”: “[email protected]”,
“subject”: “Password Reset”,
“html”: “<p>Click here to reset…</p>”
}
No SMTP connection management. No TLS negotiation. No authentication quirks. Just HTTP requests. Your application is probably already making HTTP requests to other services. Email becomes just another API call.
That said, all major email services also support SMTP relay. You can use their infrastructure with traditional SMTP if you prefer. The API is just a nicer interface for programmatic sending.
Email services provide template engines with merge variables, conditional content, and version control. You upload your email template once, then reference it by name when sending. This separates content from code.
With basic SMTP, templates are in your application code or database. Changing email copy requires deploying code or database updates. With email services, marketing can update templates through a web interface without touching your codebase.
Some services like Customer.io and SendGrid even provide visual template builders. Your marketing team can design emails without knowing HTML.
Email services automatically process bounces and categorize them. Hard bounces (invalid addresses) get flagged immediately so you can clean your list. Soft bounces (temporary failures) trigger automatic retries with exponential backoff.
Spam complaints (when users click “Report Spam”) are tracked and reported to you via webhooks. Email services will automatically suppress these addresses from future sends to protect your sender reputation.
With basic SMTP, you need to parse bounce messages yourself. They come in dozens of formats depending on the receiving mail server. Writing a robust bounce parser is surprisingly complex. Most developers skip it and just accumulate invalid addresses that hurt deliverability.
Sending commercial email has legal requirements. CAN-SPAM Act in the US requires unsubscribe links, physical address, and specific header formatting. GDPR in Europe has strict rules about consent and data handling.
Email services provide built-in compliance features. Unsubscribe links are automatically added and managed. When someone unsubscribes, they’re globally suppressed across all your sends. Physical address management and list-unsubscribe headers are handled automatically.
DIY SMTP means implementing all of this yourself. Miss a requirement and you’re violating federal law. The FTC can fine up to $51,744 per email for CAN-SPAM violations.
Email services look expensive until you calculate what building equivalent functionality actually costs.
Let’s look at typical pricing for transactional email services. SendGrid starts at $20/month for 40,000 emails, with overage at $0.50 per 1,000 emails. Mailgun starts at $35/month for 50,000 emails. Amazon SES charges $0.10 per 1,000 emails sent (no monthly minimum).
For low volume, this adds up. Sending 5,000 emails per month costs essentially nothing with DIY SMTP but $20-35/month with a service. That’s $240-420 per year for something that could be free.
But what are you actually comparing?
Running your own SMTP server has costs beyond hosting. First, there’s the technical time. Setting up Postfix correctly takes hours. Configuring SPF, DKIM, and DMARC requires DNS changes and key management. Monitoring deliverability is ongoing work.
If you value your time at $100/hour (a modest developer rate), spending 10 hours on initial setup is $1,000 in cost. Spending 2 hours per month on monitoring and maintenance is $2,400 per year. Suddenly that free SMTP looks expensive.
Then there’s deliverability. If your emails land in spam 30% of the time, you’re losing 30% of your business. Password reset emails that don’t arrive mean frustrated users who don’t complete registration. Order confirmations in spam mean support tickets asking “did my payment go through?”
According to Litmus State of Email Analytics report, the average email marketing campaign generates $42 for every $1 spent. If poor deliverability costs you even 10% of email-driven revenue, the loss far exceeds the cost of an email service.
If you’re running your own mail server (not just using hosting provider SMTP), there are additional infrastructure costs. A dedicated IP for email reputation costs $2-5/month. A VPS to run the mail server might be $10-20/month. Monitoring services to watch blacklists could be another $10/month.
You also need to handle scaling. If your application suddenly gets traffic spikes, can your mail server handle 10x normal volume? Email services scale automatically. Your single VPS might not.
For most applications, email services become cost-effective around 50,000+ emails per month. Below that, DIY SMTP can work if you have good infrastructure and technical expertise. Above 100,000 per month, email services are almost always cheaper when you factor in the engineering cost of building equivalent reliability.
The exception? If you’re already running significant infrastructure and have ops team bandwidth. Companies like GitHub and Netflix run their own email infrastructure because they operate at massive scale and have dedicated teams. But they’re investing millions in email infrastructure. You probably aren’t.
Despite email services’ advantages, there are legitimate use cases where running your own SMTP server is the right choice.
If you’re sending a few hundred emails per month, paying $20-35/month for an email service is overkill. Password resets for your side project, contact form submissions, and basic notifications don’t justify the cost.
For this use case, your hosting provider’s SMTP works fine. At WebHostMost, our SMTP infrastructure is already configured with proper SPF/DKIM, our IPs have good reputation, and you can send transactional email without additional costs.
The key is “transactional” and “low volume.” If you’re sending marketing emails or growing past 1,000 emails per month, reconsider.
For internal tools that send email only within your organization, deliverability is less critical. If your monitoring system sends alerts to your team’s email addresses, those aren’t going through spam filters. You control both the sender and recipient infrastructure.
Internal applications also don’t need analytics, bounce handling, or compliance features. A simple SMTP server sending to your company’s mail server is sufficient.
Some industries have strict requirements about where email data can be processed. Healthcare applications subject to HIPAA might not be able to send PHI through third-party email services without Business Associate Agreements.
Similarly, if you’re handling sensitive data that can’t leave your infrastructure, DIY SMTP might be required. This is rare but legitimate. Just make sure you’re actually required to do this and not overestimating compliance requirements.
If you’re learning email infrastructure or building an email service yourself, running your own SMTP server is educational. Understanding how email works at the protocol level makes you a better developer.
Just don’t use your learning environment for production email. Test on your own domains, send to yourself, and be prepared for deliverability issues.
Once you’re sending tens of millions of emails per month, the economics change. Building in-house infrastructure might be cheaper than paying per-email to a service.
But this only applies if you have dedicated ops team capacity. The engineering cost needs to be amortized over massive volume. Most startups that think they’re at this scale actually aren’t. Airbnb sends millions of emails daily and uses SendGrid. If they’re not DIYing it, you probably shouldn’t either.
Email services justify their cost in specific scenarios where their infrastructure provides clear value.
If you’re sending marketing emails or newsletters, use an email service. The deliverability difference is night and day. Consumer mailbox providers (Gmail, Outlook, Yahoo) are extremely aggressive about filtering marketing email. Without proper infrastructure, your emails vanish into spam.
Email services maintain relationships with these providers. They participate in feedback loops where Gmail tells them “this email was marked as spam by the user.” They can proactively remove problem senders before they damage shared IP reputation.
Also, marketing email has strict compliance requirements. CAN-SPAM requires unsubscribe links and physical addresses. Email services handle this automatically. DIY means building unsubscribe management, suppression lists, and compliance reporting yourself.
Once you’re sending 10,000+ transactional emails per month, email services become cost-effective. At this volume, deliverability matters significantly. If 5% of password reset emails don’t arrive, that’s hundreds of frustrated users per month.
Email services provide monitoring, analytics, and automatic issue detection. You’ll know immediately if deliverability drops. With DIY SMTP, you might not notice until users start complaining.
If you’re sending email from multiple domains (common in SaaS platforms where customers use custom domains), email services simplify configuration. Each domain needs SPF/DKIM setup. Managing this across dozens of domains is tedious with DIY SMTP.
Email services let you add domains through a dashboard. They generate DKIM keys, provide SPF records, and verify domain ownership. The complexity is abstracted away.
If your application serves users globally, email services have edge locations that reduce latency. When a user in Australia triggers a password reset, the email can be submitted to a local API endpoint and delivered faster than routing through your single mail server in the US.
Geographic distribution also improves reliability. If one region has networking issues, email services route around it. Your single SMTP server can’t do this.
When multiple developers need to work with email infrastructure, email services provide shared access through web dashboards and APIs. Everyone can view analytics, manage templates, and debug issues without SSH access to the mail server.
With DIY SMTP, troubleshooting requires SSH access and log file analysis. This is fine for solo developers but doesn’t scale to teams.
If you need detailed logs for compliance or audit purposes, email services maintain comprehensive records. Every email sent, delivered, opened, or bounced is logged with timestamps and full headers.
DIY SMTP logs exist but require active management. Logs rotate, get deleted, or fill disk space. Email services retain logs according to their retention policies (often 90 days or more) without you managing storage.
Many successful companies use both DIY SMTP and email services. This hybrid approach optimizes for different email types.
Send transactional email (password resets, order confirmations) through your own SMTP or hosting provider. These are low volume, time-sensitive, and have different reputation requirements than marketing email.
Send marketing email (newsletters, promotional campaigns) through an email service. These are high volume, have strict compliance requirements, and benefit from sophisticated deliverability infrastructure.
This separation also protects your transactional email reputation. If marketing campaigns get flagged as spam, it doesn’t impact password resets.
Configure your application with primary and fallback SMTP providers. Try your own SMTP first. If it fails, automatically fall back to an email service.
This provides reliability without paying for every email through a service. Most emails go through free SMTP. Only failures trigger paid backup delivery.
Implementation is straightforward. Catch SMTP exceptions, increment a failure counter, and switch to backup provider after threshold. Reset the counter on successful sends.
Send low-volume email through DIY SMTP up to a threshold (like 1,000 emails per day). Above that threshold, switch to an email service.
This optimizes costs for variable workload. Most days you might send 500 emails and pay nothing. On busy days when you send 5,000 emails, you use the email service and pay for the overage.
Route email differently based on sending domain. Your primary domain sends through established SMTP with good reputation. New customer domains send through email services until they build reputation.
This is common in SaaS platforms. When customers add custom domains, you can’t immediately send high volume from those domains without warming them up. Email services handle this warm-up process automatically.
Marketing from email services claims they’ll magically fix your deliverability. Your hosting provider claims their SMTP is just as good. What actually matters for inbox placement?
Email deliverability is primarily determined by sender reputation. This is a score that ISPs (Gmail, Outlook, Yahoo) calculate based on your sending behavior. Good reputation means inbox. Bad reputation means spam folder or rejection.
Reputation is calculated based on multiple signals according to Return Path’s Sender Score methodology. Spam complaints matter most. If users mark your emails as spam, your reputation tanks. Bounce rates matter too. Sending to invalid addresses signals poor list hygiene. Engagement matters increasingly. If users open and click your emails, reputation improves.
Email services help reputation by managing shared IP pools. They monitor abuse and remove bad senders before they damage everyone’s reputation. But they can’t fix fundamental problems with your email program.
If you’re sending spam, no email service will save you. If users don’t want your emails, technical infrastructure doesn’t matter. Deliverability is ultimately about sending good email that recipients want to receive.
SPF, DKIM, and DMARC are no longer optional. Gmail and Yahoo’s 2024 requirements (mentioned in our previous SMTP guide) mandate these for bulk senders.
Email services configure authentication automatically. They sign your emails with DKIM, provide SPF records, and help set up DMARC policies. With DIY SMTP, you’re responsible for this configuration.
But authentication alone doesn’t guarantee delivery. It’s a prerequisite, not a solution. Authenticated spam is still spam.
Email content significantly impacts deliverability according to Validity’s Email Deliverability Guide. Spam filters analyze subject lines, body content, HTML structure, and link patterns.
All-caps subject lines trigger filters. Excessive exclamation marks trigger filters. Misleading subject lines (saying “Re:” when it’s not a reply) trigger filters. Too many links or links to suspicious domains trigger filters.
Email services don’t fix bad content. Some provide content analysis tools that warn about spam triggers, but ultimately you need to write email that isn’t spammy.
This is where email services provide real value. There are two types of reputation: IP-based and domain-based.
IP reputation is associated with the IP address sending email. If you send from a shared hosting server, you’re sharing IP reputation with all other customers on that server. One bad sender can damage everyone’s deliverability.
Domain reputation is associated with your sending domain. This is why you can’t just switch email services to escape reputation problems. If your domain has bad reputation from past abuse, it follows you regardless of infrastructure.
Email services primarily provide good IP reputation through managed pools. Your domain reputation is still your responsibility. But starting with good IP reputation gives you a foundation to build domain reputation properly.
New IP addresses and new domains have no reputation. If you suddenly start sending thousands of emails from a fresh IP, ISPs treat it as suspicious. This looks like spam bot behavior.
Email services handle IP warm-up automatically. They gradually increase sending volume from new IPs over weeks. They monitor delivery rates and adjust volume based on response.
With DIY SMTP, you need to manage warm-up manually. Start with low volume to trusted addresses, gradually increase, and monitor bounce rates. Skip this and your deliverability suffers for months.
Let’s get real about the technical complexity of running production email infrastructure. It’s not just “install Postfix and configure SMTP.”
A production-ready mail server requires dozens of configuration decisions. Which MTA to use (Postfix, Exim, Sendmail)? How to handle queue management and retries? What rate limiting to implement? How to prevent open relay vulnerabilities?
According to Postfix’s documentation, basic configuration alone involves setting up 20+ parameters correctly. Advanced features like content filtering, rate limiting, and authentication add complexity.
Email services abstract this entirely. You don’t manage MTAs. You make API calls or configure SMTP credentials.
Production email infrastructure requires monitoring. Is the mail server processing queue normally? Are there unusually high bounce rates? Are any IPs blacklisted? Is disk space filling up with queued messages?
You need to set up monitoring systems, define alert thresholds, and have on-call processes for when things break. Email services handle this for you with built-in monitoring and status pages.
Mail servers are security-critical infrastructure. They need regular updates for security vulnerabilities. Configuration needs hardening against spam relay, authentication bypass, and DoS attacks.
You’re responsible for TLS certificate management, rotating DKIM keys periodically, monitoring for brute force authentication attempts, and implementing rate limiting to prevent abuse.
Email services manage security as part of their service. They patch vulnerabilities, rotate infrastructure, and handle security monitoring.
If your IP gets blacklisted (and it will eventually, even if you do everything right), you need to detect it and get delisted. There are hundreds of blacklists. Some are legitimate and impact deliverability. Others are pay-to-delist scams.
You need monitoring systems that check major blacklists regularly. When blacklisted, you need to identify the cause, fix it, and submit delisting requests. This can take days or weeks.
Email services monitor blacklists as core infrastructure. They have relationships with blacklist operators and can often get delisted faster than individuals.
Email logs are verbose. A busy mail server generates gigabytes of logs daily. You need log rotation, retention policies, search infrastructure, and analysis tools.
For compliance or debugging, you might need to find a specific email from weeks ago. Searching raw mail logs is painful. You need structured logging, indexing, and query tools.
Email services provide searchable logs through web dashboards. You can find any email by recipient, subject, timestamp, or delivery status without grep-ing through gigabytes of files.
Theory is one thing. Let’s look at what actually happens when companies switch between DIY SMTP and email services.
A typical story: startup builds MVP using their hosting provider’s SMTP. It works fine for the first 100 users. Password resets send instantly. No complaints.
They launch and grow to 1,000 users. Suddenly deliverability drops. Users complain that password resets don’t arrive. Customer success is overwhelmed with “I never got the email” tickets.
Investigation reveals their hosting provider’s IPs are on multiple blacklists. Another customer on the shared server was sending spam. The entire server’s reputation tanked.
They switch to SendGrid. Migration takes a day. Deliverability immediately improves to 95%+. Customer complaints drop to nearly zero. They wish they’d made the switch earlier instead of dealing with support tickets.
Cost? $35/month for SendGrid. Value? Hundreds of saved support hours and better user experience that improves conversion and retention.
A different story: enterprise company builds custom email infrastructure. They hire a dedicated email team, run their own Postfix clusters, implement sophisticated monitoring, and manage deliverability themselves.
Annual cost? Three engineers at $150K each is $450K in salary. Infrastructure is another $50K. Total: $500K/year for email infrastructure.
They’re sending 10 million emails per month. At SendGrid’s pricing, this would cost roughly $5,000/month or $60K/year. They’re spending 8x more building it themselves.
Why? “We have special requirements” and “we want control.” But when you dig into the requirements, they’re not actually that special. They could use SendGrid with minor architectural changes.
The lesson? Don’t build custom infrastructure without clear ROI. Email services are commoditized for good reason. Unless you’re operating at Google scale, you’re probably overpaying to DIY.
Smart approach: SaaS company uses hosting SMTP for transactional email during beta with 50 test users. Total cost: $0. Deliverability is fine because volume is tiny.
At launch, they immediately configure SendGrid for all production email. As they scale to thousands of users, deliverability remains solid. They never deal with blacklist issues or reputation problems.
They focus engineering time on their product instead of email infrastructure. Email “just works” and they never think about it. This is the correct approach for most SaaS companies.
Here’s a practical framework for deciding between DIY SMTP and email services based on your actual needs.
Start with these questions. How many emails do you send per month? What types of emails (transactional, marketing, internal)? What’s your deliverability requirement (okay with 80% or need 95%+)? Do you have ops team capacity for email infrastructure? What’s your budget for email infrastructure?
If you’re sending fewer than 5,000 emails per month, all transactional, deliverability requirements aren’t strict, and you have no ops capacity, use your hosting provider’s SMTP. The cost of email services isn’t justified.
If you’re sending 5,000-50,000 emails per month, mostly transactional with some marketing, deliverability matters but isn’t mission-critical, and you have some ops capacity, consider starting with hosting SMTP and switching to an email service when you hit problems. The risk is support burden from deliverability issues.
If you’re sending 50,000+ emails per month, any marketing email, deliverability is mission-critical (password resets must arrive instantly), or you have no ops capacity, use an email service from the start. The cost is easily justified by improved deliverability and reduced engineering overhead.
Certain situations scream “use an email service.” If you’re sending any marketing or bulk email, DIY is risky. Marketing email has strict compliance requirements and aggressive spam filtering. Email services are designed for this.
If you don’t have ops team capacity, don’t run your own mail server. Managing production email infrastructure requires ongoing attention. Hoping it “just works” leads to outages.
If you’ve had deliverability issues with DIY SMTP in the past, switch to an email service. Reputation damage is hard to recover from. Starting fresh with a service’s established reputation is easier than fixing your own.
If you’re growing quickly, plan for email services. Scaling email infrastructure is complex. Email services scale automatically. DIY means managing queue processing, rate limiting, and deliverability at increasing volume.
If you’re sending low-volume transactional email and it’s working fine, don’t fix what isn’t broken. The cost of migrating to an email service might not be justified.
If you have dedicated ops capacity and are operating at massive scale (millions of emails per month), the economics might favor DIY. But only if you can amortize engineering cost across huge volume.
If you have legitimate compliance requirements that prevent using third-party email services, DIY might be necessary. Just make sure this is actually required and not assumed.
For most developers building products, this is the optimal path: start with hosting provider SMTP for MVP and early users. Monitor deliverability and user complaints. When you reach 5,000 emails per month or have any deliverability issues, switch to an email service immediately.
Use the free tier of email services (most offer 10,000-40,000 emails per month free) until you outgrow it. Once you’re paying for email services, you’re probably also making enough revenue that the cost is negligible relative to value.
Never DIY email for marketing campaigns. Always use an email service for this from day one. The compliance requirements alone justify the cost.
At WebHostMost, our SMTP infrastructure handles low-to-medium volume transactional email reliably. We maintain sender reputation, configure SPF/DKIM automatically, and provide the reliability needed for product email. When you outgrow hosting SMTP, we can guide you to the right email service for your needs.
Once you’ve decided to switch from DIY SMTP to an email service (or vice versa), the migration needs planning. Switching email infrastructure wrong can break critical user flows.
Never cut over email infrastructure without thorough testing. Set up the new email service and test with non-critical emails first. Send test emails to yourself. Verify SPF/DKIM are configured correctly. Check that emails arrive in inbox, not spam.
Test critical user flows in staging environments. Password resets, order confirmations, two-factor authentication emails – make sure everything works before switching production traffic.
Some email services offer “test mode” where you can send emails that get delivered to a test inbox instead of actual recipients. Use this for integration testing without sending real emails.
Don’t switch 100% of email traffic instantly. Roll out gradually. Send 10% of email through the new service, monitor for issues, then increase to 25%, 50%, and finally 100%.
This limits blast radius if something breaks. If the new email service has configuration issues or deliverability problems, only a fraction of users are impacted.
Implement feature flags or configuration switches that let you control the rollout percentage. This also provides instant rollback capability if needed.
Watch key metrics closely during migration. Delivery success rates, bounce rates, spam complaint rates, and time-to-delivery should remain stable or improve.
Set up alerts for significant deviations. If bounce rate suddenly spikes from 2% to 10%, something is wrong. Investigate immediately instead of waiting for user complaints.
Compare metrics between old and new infrastructure during overlap period. If new service is consistently better, proceed with cutover. If metrics are worse, investigate before switching more traffic.
When switching email services, you’ll need to update DNS records. SPF records change to authorize the new service. DKIM keys are regenerated. DMARC policies might need updates.
DNS changes take time to propagate. Plan for 24-48 hours of both systems being partially active. Don’t remove old DNS records immediately. Keep them for a week to ensure cached records expire.
Some organizations maintain multiple email services in SPF records. This provides redundancy and allows instant switching between providers if needed.
Warn your support team about the migration. Brief them on potential issues like delayed emails or temporary deliverability problems. Prepare response templates for user complaints.
Consider announcing the migration to users if email is critical to your product. Set expectations that some emails might be delayed during a specific time window.
Have rollback procedures documented and tested. If migration fails, you need to quickly revert to the old system. Practice rollback in staging to ensure it works under pressure.
Here’s the truth: most developers spend too much time thinking about email infrastructure and not enough time building products users care about.
Email is commodity infrastructure now. The technical problems are solved. SPF/DKIM/DMARC work. Email services have proven deliverability. Your hosting provider’s SMTP handles low volume fine.
Stop optimizing for edge cases that don’t matter. Stop worrying about saving $20/month on email services when your time is worth $100/hour. Stop building custom email infrastructure when excellent services exist.
Use your hosting provider’s SMTP until you hit problems or reach moderate volume. When email becomes important enough to think about, pay for an email service and forget about it. Focus your engineering effort on features that differentiate your product.
Email should be boring infrastructure that works reliably. It shouldn’t be an engineering project unless you’re building an email company.
