Several transactional email providers have simple REST APIs. Common options include:

  • SendGrid — straightforward REST API, widely used
  • Mailgun — simple REST API for sending and tracking email
  • Postmark — known for a very clean, easy-to-use API
  • Amazon SES — has an API, but is less “simple” than the others
  • Mailjet — REST API with transactional email support

If you want the simplest developer experience, Postmark and SendGrid are often the easiest to start with.

If you want, I can also compare them by pricing, deliverability, and ease of integration.
