SMTP Settings

This section explains the functionality of SMTP Settings and provides some related use cases to assist you in creating an optimal configuration.
To access the SMTP settings, go to Company > Company Settings > SMTP Settings.

What is SMTP used for?

The Simple Mail Transfer Protocol (SMTP) is an internet standard communication protocol for email transmission. The platform includes a default email service available to all customers; however, you also have the option to use your own email server to send phishing, training and other emails.
If you have the Phishing Simulator module, enabling SMTP relay authorization on the mail server will allow you to mimic brand impersonation phishing techniques, including the sender address information.

Test SMTP Settings

You can check whether the email has been sent via the defined email server by simply clicking on the Send Test Email button on the email settings page.
You will receive a notification of a successful test if everything is correct. If settings are failed, you will receive a notification of an error message that will show what’s the configuration issue.


Q: Once an SMTP connection has been configured, can I send an email on the platform with different domain addresses?

A: Yes. If your SMTP server has an SMTP relay feature enabled, you can send mail using more than one domain address. If the SMTP relay has not been activated, you can only send emails using corporate domains authorized for your email server.

Q: Can I create more than one SMTP in the system?

A: Yes. The platform offers the flexibility to use several SMTP configurations.

Q: Can I choose the SMTP to be used for a phishing or training campaign?

A: Yes. You can select the SMTP to be used when you launch a campaign at Phishing Simulator > Campaign Manager for phishing campaigns.

Q: Can I choose the SMTP to be used for my notification templates?

A: Yes. You can set the SMTP information to notification templates by editing the templates from Company Settings > Notification Templates.
