Use the SMTP email test to submit a real message through a server you specify. Server acceptance confirms that attempt was accepted for processing; check the recipient mailbox separately to confirm arrival.
Open the SMTP email test. Use a test account and a recipient you control. Extended API calls use your Spotzee credit balance; see pricing for current rates.

​
Send a test message

1

Enter the server settings

Provide the hostname or IP, port, username and password supplied by your SMTP provider. Choose the required security mode: None, STARTTLS or SSL. The API values are none, tls and ssl.
2

Set sender and recipient

Use a sender permitted by the account and a recipient you control. The test submits a real message, so avoid customer addresses or sensitive content.
3

Review the response

Inspect the reported result and diagnostics. Authentication, connection, encryption and sender restrictions can each prevent submission. Follow the provider’s configuration instructions before retrying.
4

Confirm arrival

Check the recipient’s inbox and spam folder. Successful submission alone does not prove delivery or inbox placement.

​
Protect the test credentials

The test service receives the credentials and uses them to authenticate with the SMTP server. None does not encrypt that SMTP connection. Use a dedicated test account or app password where supported, and choose encrypted transport according to your provider’s instructions. Provider authentication policies vary. This form accepts a username and password; do not assume every account supports password-based SMTP or that an app password bypasses a disabled authentication method. For a connection-only check, use the TCP port checker. To inspect a received message, use the email spam checker.
