What does Mailtrap do?
Mailtrap is an email delivery platform that serves two main functions: testing emails during development and sending production emails. The Email Sandbox component lets developers test email functionality without actually sending messages to real users, preventing accidental spam during staging. The Email API/SMTP service handles reliable sending of transactional and promotional emails with high deliverability rates.
The platform provides detailed analytics dashboards that track key email metrics including opens, clicks, and deliverability rates across different mailbox providers. It offers integrations with popular development tools like Vercel, Supabase, Cursor, and Claude Code, making it easy to incorporate into existing workflows. The service includes 24/7 support from technical engineers and email deliverability experts.
Development teams building applications that send email notifications benefit most from Mailtrap. QA testers use it to verify email content and functionality before deployment. Product teams rely on it for monitoring the performance of their email campaigns and transactional messages. The platform is particularly valuable for B2B applications, marketplaces, and any service where email communication is critical to operations.
