What it is

Two products under one account: an email sandbox that captures outgoing mail from staging so nothing reaches real users, and a production sending API and SMTP relay with deliverability analytics. Sandbox inboxes show HTML preview, spam score, blacklist checks and raw message source.

Why it earns a slot

Point your dev SMTP at Mailtrap and stop worrying about a seed script emailing your entire user table. The 4,000/mo production sending free tier is a genuine bonus on top.

Know before you commit

Testing and Sending are billed as separate products — a testing plan includes zero production sends. Free sending is capped at 150 emails/day with only 3 days of logs.
