Simulate different events by sending test emails.
During development, it's common to test different scenarios by sending test emails.
Instead of using your personal email account or setting up a fake SMTP server, you can leverage the following email addresses to simulate each event type.
This gives you full use of Resend's Dashboard, Webhooks, and API - without affecting your domain reputation.
To test that your emails are being successfully delivered, you can send an email to:
[email protected]
To test that the recipient's email provider rejected your email, you can send an email to:
[email protected]
This will generate a SMTP 550 5.1.1 ("Unknown User") response code.
To test that your emails are received but marked as spam, you can send an email to:
[email protected]
