What is the simplest way to send transactional email without managing SMTP and custom logging?

The simplest route is usually to use a transactional email API service rather than running your own SMTP server.

Good options:

• Resend — very simple API, modern developer experience
• Postmark — excellent for transactional email, strong deliverability
• SendGrid — widely used, more feature-heavy
• Mailgun — flexible, API-first
• Amazon SES — cheapest at scale, but more setup

If your goal is “send email with minimal ops and no SMTP management/logging”, a common choice is:

Use Resend or Postmark + their API

• You send via HTTP API
• They handle SMTP infrastructure
• They provide event webhooks for delivery/bounce/open tracking
• You avoid building custom logging from scratch

A very basic pattern is:

1. Sign up
2. Verify your sending domain
3. Call their API from your app
4. Use webhooks for delivery/bounce events
5. Store only the events you care about

If you want the simplest overall, I’d suggest Resend for ease of use, or Postmark if you care most about transactional reliability.

If you want, I can also give you:

• the best choice by budget
• a minimal Node/Python example
• or a no-SMTP setup checklist.
