MailCraft vs Mailtrap
Mailtrap made its name as an email testing and sandboxing tool for developers, and has since added a production sending product alongside it. If you're specifically shopping for a primary production ESP rather than a staging/testing sandbox, it's worth knowing testing is still Mailtrap's core identity.

Why teams switch from Mailtrap
A platform built from the ground up for production sending, not testing first.
Campaigns, automations and segments as core features, not extras.
Deliverability tooling (SPF/DKIM/DMARC, suppression, warm-up guidance) aimed at production senders.
An MCP server that reaches past sending into campaigns, automations and contacts, with scoped keys per agent.
