About Mailtrap: Modern Email Delivery for dev and product teams

Overview

Mailtrap is a modern email delivery platform built for developer and product teams. It combines three products in one: Email API/SMTP for reliably sending transactional and promo emails, Email Sandbox for safely testing staging emails, and Email Marketing for running promo campaigns.

The platform began in 2011 when engineers at Railsware built a fake SMTP server after a staging bug sent 10,000 test emails to real customers. Mailtrap went public at the Railsberry conference in 2012 and now serves more than 150,000 teams worldwide.

Key Benefits

  • Fast delivery and high inboxing rates for transactional and promotional email.
  • Safe email testing in staging and development environments with virtual inboxes.
  • Actionable dashboards with open and click tracking and up to 30 days of email logs.
  • 24/7 support from engineers and deliverability experts, with urgent cases addressed immediately.
  • Native integrations with Supabase, Vercel, Claude Code, Cursor, and AI clients.
  • A free tier lets teams start sending and testing without payment.

How It Works

Teams sign up, add a sending domain, and verify it with SPF, DKIM, and DMARC DNS records. They then send email through the Email API, SMTP relay, or official SDKs and monitor delivery with analytics dashboards. Developers and QAs point staging environments at the Email Sandbox to catch test messages before they reach real inboxes.

Use Cases

  • Developers and QA engineers test staging emails safely with the Email Sandbox.
  • SaaS teams send transactional messages such as password resets and order confirmations through the Email API.
  • Marketing teams run promotional campaigns with Email Marketing and track performance.
  • Product teams monitor deliverability across mailbox providers to protect sender reputation.
  • Large organizations send at scale with dedicated IPs and volume-based Enterprise plans.

Why Choose This Product

Mailtrap is bootstrapped and engineer-led, funded by customers rather than venture capital since 2011, and stands behind a 99.99% uptime SLA. Teams including PayPal, Atlassian, Adobe, Calendly, Yelp, and GoPro rely on it, and customers report switching from providers like SendGrid and Postmark for faster setup and better stats.
