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.

Test delivered emails

To test that your emails are being successfully delivered, you can send an email to:

delivered@resend.dev

Test bounced emails

To test that the recipient's email provider rejected your email, you can send an email to:

bounced@resend.dev

This will generate a SMTP 550 5.1.1 ("Unknown User") response code.

Test "Marked as Spam" emails

To test that your emails are received but marked as spam, you can send an email to:

complained@resend.dev
