AutoSend x Descope
Descope uses email for authentication flows like OTP verification, magic links, and password resets. By default, Descope uses its built-in email delivery, but you can configure it to use AutoSend SMTP for better deliverability and email tracking.

​

Make sure you have a verified domain added in AutoSend to send emails from.

API Key

Create a new API key for SMTP authentication or use the existing one.

Dynamic Values

Descope supports dynamic values in sender fields using template syntax:
  • Sender Address/Name: Use {{options_<value>}} format for dynamic sender configuration
  • Recipient: Set the To field dynamically with {{user.email}}
Refer to Descope’s Dynamic Values documentation to learn how to set dynamic values when using messaging connectors.

​
Troubleshooting

  • Verify your SMTP credentials are correct
  • Check that your sender email domain is verified in AutoSend
  • Ensure the sender address matches a verified domain
  • Check Descope connector test results for specific errors
  • Double-check your API key is correct
  • Ensure you’re using autosend as the username
  • Verify your API key is active in the AutoSend dashboard
  • Verify the hostname is smtp.autosend.com
  • Try using port 465 with implicit TLS if port 587 fails
  • Check if your network blocks outbound SMTP connections
  • Ensure your domain has proper DNS records (SPF, DKIM, DMARC)
  • Use a professional sender name, not just “noreply”
  • Check your domain reputation in AutoSend
