About

Debug Mail is a hosted fake SMTP server for testing application email flows. Developers point their app to app.debugmail.io and use the project login, password, and port shown in the dashboard to capture outgoing messages instead of delivering them to real recipients.

The service supports team-based projects, shared mailboxes, email viewing in HTML or plain text, .EML downloads, and forwarding to real addresses. The pricing page lists a perpetual free plan with 1 project, 2 team members, unlimited test emails per day, 1 forwarded email per day, and 10MB mailbox storage per team.

This free tier is genuinely usable for a small team: it includes one project, two members, unlimited test emails, and a small amount of forwarding and storage. Compared with the cheapest paid Silver plan at $2 per user per month, it delivers roughly three-quarters of the core day-to-day capability but with much tighter collaboration and forwarding limits, so about $1.50/month is a fair buyer-style estimate. A credit card is not required, and the offer is perpetual but capped.

What's included in the free tier

  • Access to 1 project.
  • Access for up to 2 team members.
  • Unlimited test emails per day.
  • Forwarding up to 1 email per day.
  • 10 MB mailbox storage per team.
