Send a test email to confirm a connection works, whether you’re finishing the setup wizard or checking a connection you added later.
- In the BooleanSMTP sidebar, click Test Email.
- In Select Mailer, choose the connection you want to test.
- In To Address, enter an address you can check right now.
- Click Send Test Email.

You see Test email sent successfully! when the send transport reports success. Check that inbox — and its spam folder — for the email.
If you see Test email failed to send, the message under it is the provider’s reason. The most common causes are a mistyped key or password and a From address the provider has not verified.
Check its send status
If email logging is enabled, click Logs in the BooleanSMTP sidebar. Email Logs lists recorded send attempts, newest first. The tabs filter them: All, Successful, Simulated, Failed and Pending.

Your test email should be under Successful. Click it to see its details. This status does not confirm arrival in the recipient inbox.
