Mailtrap
Mailtrap is an email testing and delivery platform that helps developers test, send, and track emails safely before reaching real users.





What is Mailtrap
Mailtrap is a dual-purpose email platform. First, it offers Email Sandbox, which acts as a fake email server that captures all test emails from your development or staging environment. You can inspect every detail of these emails without sending them to real people. This prevents accidental emails to customers during testing.
Second, Mailtrap provides Email API and SMTP service for sending real emails to your users once testing is complete. This includes transactional emails like password resets and promotional campaigns. The platform gives you detailed tracking, showing delivery rates, opens, clicks, and bounces.
Mailtrap supports all major programming languages and frameworks through ready-made code snippets, making integration quick and straightforward for any development team.
How to Use Mailtrap
Using Mailtrap is simple for both testing and sending emails. Here are the steps:
Sign up for a free account at mailtrap.io and verify your email address.
For email testing, go to Email Sandbox and create a new sandbox inbox. Copy the SMTP credentials provided and add them to your application settings.
Send test emails from your app. They will appear in your Mailtrap sandbox instead of going to real email addresses. Check the HTML, text, spam score, and attachments.
Use the HTML checker to see how your email looks across different email clients like Gmail, Outlook, and Apple Mail.
For sending real emails, add and verify your domain in the Email Sending section by adding DNS records.
Integrate the API or SMTP credentials into your production environment. Monitor email performance through the dashboard to track delivery and engagement.
