What is MailGrab?

MailGrab is a developer-focused email testing and debugging service that acts as a fake SMTP server for staging environments.

You configure your application’s staging environment to use MailGrab’s SMTP credentials instead of a real mail server. Every email your app would normally send—welcome messages, password resets, invoices, etc.—is captured by MailGrab instead of being delivered to real inboxes.

Key features:

  • Rendered HTML preview: View emails as they appear in desktop and mobile clients.
  • Raw headers & attachments: Inspect full email headers and download attachments.
  • Compatibility checks: See how your HTML/CSS renders across Gmail, Outlook, Apple Mail, and more using Can I Email support data.

Supports teams, public share links for single emails or entire inboxes.
