API Keys

An API Key is required when utilizing SMTP2GO's API, WordPress Plugin, OSS Integrations or cPanel/WHM Plugin.

You manage API Keys from your account dashboard's "Sending > API Keys" page:


To create an API Key, click the "Add API Key" button, set your desired permissions and settings, then click the "Save" button. There is no limit on the number of API Keys that can be added to a paid account.
The API Key is not editable/customizable.

For API Keys, you can set an optional description, rate limit, and further settings including:

  • Permissions: Enable/disable certain permissions that the API key has access to. 
  • Unsubscribe Footer: Add an Unsubscribe Footer to emails - suppression management is handled on your account's 'Reports > Suppressions' page.
  • Tracking & Status: Enable/disable Open Tracking, Click Tracking or enable/disable the API Key.
  • Advanced: Enable/disable Email Archiving for the API Key (available on paid plans or if a subaccount the permission to use Archiving will need to be enabled by the master account), enable/disable the Email Auditing feature to have BCC copies of emails sent to designated email addresses or enable/disable Bounce Notifications which can be sent back to the original sender or a designated email address.
