SMTP Users are username and password combinations used to authenticate when your email client or sending software connects to our SMTP servers.
By default, authentication via a username and password is expected. If your software does not allow entering a username and password for authentication, please view the alternative authentication options we offer (IP Authentication and Address Authentication).
SMTP Users are managed on your account's "Sending > SMTP Users" page.
To add an SMTP User, click the 'Add SMTP user' button on the right side of the page, set a customized username, password, description (optional) and rate limit (optional). Further specific settings are controlled in each SMTP User's settings which include:
- Unsubscribe Footer: Add an Unsubscribe Footer to your emails - suppression management is handled on your account's 'Reports > Suppressions' page.
- Tracking & Status: Enable Open Tracking, Click Tracking or set the status to allowed, blocked or sandboxed.
- Advanced: Enable Email Archiving for the SMTP User, enable the Email Auditing feature to have BCC copies of emails sent to designated email addresses or enable Bounce Notifications which can be sent to the original sender or a designated email address.
To remove an SMTP User, press the 'X' button on the far right side of the row.
There is no limit on the number of SMTP Users that you add to your account and it is a great way to keep separation for different senders or setups.
The primary reason why creating multiple users is a good idea, is so you can easily prevent spam being sent through your account in the event of one of your usernames/passwords becoming compromised. If spam does get sent through your SMTP2GO account, you will be able to change the offending username/password, and advise the affected sender to immediately scan their computers for viruses/trojans. Your other senders won't need to update their details. Another benefit is you can easily filter reporting per SMTP User.
For full separation of sending, we recommend the Subaccount feature.
