Overview
Mandrill and Mailtrap serve different developer needs. Mandrill is a Mailchimp add-on for production transactional email. Mailtrap uniquely combines email testing (sandbox) with production sending. For our take on each, see our Mandrill comparison.
Mailtrap's Testing Advantage
Mailtrap's email sandbox catches emails during development — no accidental sends to real customers. Analyze HTML rendering, check spam scores, validate content, and debug email issues before they reach production. Mandrill has no testing environment. For development teams, this alone justifies switching.
The Combined Workflow
Mailtrap lets you use one platform for both testing and production. Develop with the sandbox, analyze with testing tools, then switch to production sending. Mandrill requires a separate solution for email testing during development.
