Mailtrap Review

Worth it

Best for

  • Buyers wanting a big, funded vendor with enterprise SLAs

Gotchas - check before you buy

high

Mailtrap SMTP credentials have been found sold on cybercrime marketplaces — rotate keys, enforce 2FA

medium

Two separate pricing tracks (sending vs testing) — needing both roughly doubles cost

medium

Symfony's Mailtrap mailer bridge shipped an unauthenticated webhook bypass (CVE-2026-45755); keep frameworks patched

low

Trustpilot footprint tiny (19 reviews, 3.6) — hard to verify long-term support claims

  • CVE-2026-45755 — auth bypass in Symfony Mailtrap mailer bridge, Medium-severity flaw in symfony/mailtrap-mailer: webhook parser never verifies signatures. Affects the Symfony integration, not Mailtrap's platform itself. Patch the bridge.
  • Credentials sold on cybercrime markets (2024), SendGrid and Mailtrap credentials were offered for sale, indicating customer credential theft risk rather than a platform breach.
