Email delivery platform with an email testing sandbox.
Top-rated in Email Testing#1 of 5 in Email Testing by Overall Score
Mailtrap provides an email API/SMTP for transactional and bulk sending plus an email sandbox for testing emails before they reach real inboxes.
Mailtrap separates pre-production testing from production sending. Its Email Sandbox can inspect HTML, headers, spam signals, bounces, and rendering without reaching real recipients, while the sending side gives developers SMTP and API routes for live transactional mail; that two-environment approach is useful in software release and QA workflows.
