Do I need a dedicated email service for my app?

Not always.
You need a dedicated email service if your app sends any of the following:
- Transactional emails: signups, password resets, receipts, verification codes, alerts
- Marketing emails: newsletters, promos, drip campaigns
- High volume: lots of messages or spikes in traffic
- Reliability needs: you care about delivery, retries, bounce handling, spam avoidance
- Tracking/compliance: open/click tracking, unsubscribe management, logs, suppression lists
You can often skip a dedicated service if:
- Your app sends only a few emails
- They’re internal/test emails
- Email is not core to the product
- You’re in very early development and just need a quick prototype
Why use a dedicated service?
A provider like SendGrid, Postmark, Mailgun, Amazon SES, Resend, etc. gives you:
- Better deliverability
- Easier SMTP/API integration
- Bounce and complaint handling
- Templates
- Rate limiting and retries
- Domain authentication support (SPF, DKIM, DMARC)
Rule of thumb
- Prototype / tiny app: your own SMTP or a basic provider may be enough
- Production app: use a dedicated email service
- Anything important or user-facing: strongly recommended
If you want, I can help you choose between SMTP vs email API or recommend a provider based on your app type and budget.
