Modern local SMTP catcher.
Switching as SaaS product teams
A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.
Mailpit does not cover multi-tenant support, event stream, the suppressions API, scheduling, and webhook coverage. Mailtrap, MailSlurp, and Litmus close that gap. The order below weighs this audience's priorities first, so it differs from a general popularity ranking.
