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.
