SMTP Integration
Configure outbound SMTP for candidate invitations, interview reminders, assessment results, and other email communications.
Overview
SMTP lets Xinterview AI send outbound email through your own mail server for candidate invitations, interview reminders, assessment results, and other communications.
Configure SMTP
Verify your SMTP host, port, username, password, and sender address with an SMTP test tool before you save the configuration.
Collect your SMTP details
Gather the settings from your email provider or mail server:
-
SMTP host
-
SMTP port
-
Username
-
Password
-
Sender email address
-
Encryption type, if your provider requires one
Confirm that the sender address matches the domain you are authorized to use.
Enter the SMTP settings
Open the SMTP integration settings in Xinterview AI and enter the values provided by your mail server.
Settings > Integration > SMTP Configuration
Use the same credentials that your provider uses for authenticated outbound mail. If your provider supports multiple ports or encryption modes, choose the combination that matches the server configuration you tested.
Save and test delivery
Save the configuration, then send a test email.
A successful test email is the only indication that the configuration works. If the message does not arrive, review the host, port, credentials, encryption setting, and sender address before trying again.
Xinterview AI cannot verify whether the SMTP configuration you entered is correct. Successful test email delivery is the only indication that the setup works.
SMTP Configuration Best Practices
-
Use TLS encryption (port 587) when available.
-
Store passwords securely and never commit them to version control.
-
Enable SSL verification in production environments.
-
Test your configuration before going live.
-
Monitor email delivery logs regularly.
-
Set up email authentication with SPF, DKIM, and DMARC.
-
Configure appropriate retry and timeout values.
-
Use a dedicated sender email address.
-
Regularly update SMTP credentials and rotate passwords.
FAQs
Use the exact SMTP host and port provided by your email provider or mail server administrator. If more than one option is available, use the one recommended for authenticated outbound mail.
Recheck the host, port, username, password, encryption setting, and sender email address. Then send another test email after correcting any mismatch.
Use the encryption method your provider requires. If TLS is available, it is usually the preferred option for secure delivery.
Verify them with your mail provider first, then test the same details in Xinterview. A successful test email is the clearest confirmation.
Please double-check your SMTP username, password, port number, and SSL/TLS settings. Authentication errors are usually caused by incorrect SMTP details or unsupported security settings. Before adding the credentials to the platform, test them using an external SMTP testing tool to confirm they are working correctly.
Saving the configuration does not guarantee delivery. Check authentication records like SPF, DKIM, and DMARC, and review your mail server logs if messages are still failing.
