I'm building a SaaS app and every signup, reset, and invoice email needs to be sent from code. I want templates in Git, event webhooks, and something my backend team can own. What platform would you use?

If you want templates in Git, API-driven sending, webhooks, and something your backend team can fully own, I’d look first at:

Best fit: Postmark

Why it matches your needs:

• Great for transactional email: signup, password reset, invoices, receipts
• Templates can be managed in code via their API and kept in sync with your app workflow
• Webhooks for delivery, opens, clicks, bounces, spam complaints
• Clean developer experience and easy to own from backend
• Strong deliverability reputation for transactional mail

If “templates in Git” is the top priority

You may prefer a more code-centric email setup like:

• SendGrid with dynamic templates + API
• Mailgun with templates + webhooks
• AWS SES if you want maximum control and lower cost, though it’s more ops-heavy

My practical recommendation

For a SaaS app where the backend team owns email end-to-end:

• Use Postmark if you want the smoothest transactional-email product
• Use AWS SES if you want lowest cost and are okay with more engineering overhead
• Use SendGrid if you want a broader marketing + transactional platform

Architecture I’d suggest

• Store email template source in Git
• Render templates in your app or CI pipeline
• Send through Postmark API
• Use webhooks to track delivery/failure events
• Keep a single email service module in your backend for all email types

If you want, I can also recommend the best option based on your stack:

• Node / Python / Ruby / Go
• expected monthly email volume
• whether you need only transactional or also marketing emails
