Test with real email addresses

Use MailSlurp to test critical application functions (like user sign-up and account confirmation) with real email addresses.

Test your app properly

MailSlurp let’s you create test email addresses on demand that you can send and receive real email with. Test your application fully, end-to-end, using real test email accounts. It’s free for personal use and is built on scalable cloud infrastructure.

How it works

MailSlurp is an email API that is callable via REST API, SDK libraries, or visual dashboard. MailSlurp let’s you create email addresses on demand, either randomly generated or specified using your own custom domains.

In practice

MailSlurp is based around inboxes: modern abstractions on an underlying SMTP protocol. Using the API or SDKs you can create inboxes dynamically during each test run.

const { emailAddress } = mailslurp.createInbox();

Calling the API without arguments assigns you a randomized address ending in @mailslurp.com. To use your own domain simply register the correct MX records inside our dashboard and the pass your desired email address to the create method.

const { emailAddress } = mailslurp.createInbox({ 
  emailAddress: 'test5@mydomain.com'
});

Use cases

MailSlurp users create thousands of emails each day and use them for a wide range of test purposes. Imagine:

  • Testing user sign-up end to end with real email addresses
  • Extracting email verification codes from within tests
  • Testing transaction emails and attachments with automated tests
  • And more!
