Every SaaS needs transactional email

Welcome emails. Password resets.
Account alerts.

Most indie developers end up running several SaaS projects. Each one needs its own sending domain. DevSMTP is priced with that reality in mind.

DevSMTP gives you one place to send and monitor transactional emails across all your projects, with tooling that fits how developers actually work.

Use it for production. Use MCP when you want. Ignore it when you don't.
