Overview & What is Mailtrap?

Mailtrap Fake SMTP Server provides a safe and isolated environment for developers to test, view, and debug emails sent from their applications during development and staging. Instead of sending emails to real recipients, Mailtrap captures all outgoing emails and displays them in a virtual inbox. This allows developers to inspect email content, headers, and identify potential issues before deployment, ensuring a flawless email experience for end-users. It's an indispensable tool for preventing accidental spamming and maintaining data privacy during the development cycle.
