Bounce Emulator

Constructing the address

The recipient's username should start with bounce+ and contain the response in URL-encoded form: [email protected] .

To create it, use https://www.urlencoder.org or any other URL encoding solution.

Tip: You cannot use capital letters because email addresses are converted to lowercase by any responsible SMTP client. But you can use URL encoding to express capital letters: bounce+550+%[email protected] .

Using Bounce Emulator with an email client

Just use the inbox.mailtrap.io host with any email client or application and send an email to [email protected] .

Using Bounce Emulator with Sandbox

If your application is connected to Email Sandbox SMTP, send an email from the application to [email protected] , and your application will receive a bounce response from the Sandbox SMTP server.

Note: This feature does not work with API, as bounce codes are specific to SMTP.
