Extensions

User Extensions allow you to create unique, disposable variations of your email address by adding a suffix to your username. These are perfect for tracking who is selling your data, organizing sign-ups, or creating temporary contact points without revealing your primary address.

Extensions use the format: user-extension@domain.com.

Add a static extension

A static extension creates one specific address. For example, if your username is kim, creating an extension called shopping results in kim-shopping@domain.com.

  • Log in to your User Panel. Use your full email address and password to sign in.

  • Click the Extensions icon.
  • Click the Add Extension button.
  • Name your extension: Enter a word (e.g., sales).
  • Set the destination: Enter the email address where messages should be delivered (usually your full email address).
  • Click Add Extension.

 

Add a dynamic (wildcard) extension

Dynamic extensions act as a "catch-all" for any variation following your keyword. If you create a wildcard extension named project, it will accept mail sent to user-project-anything@domain.com.

  • Log in to your User Panel. Use your full email address and password to sign in.

  • Click the Extensions icon.
  • Click the Add Extension button.
  • Name your extension: Enter your keyword followed by -default (e.g., sales-default).
  • Set the destination: Enter your email address in the Deliver to field (usually your full email address).
  • Click Add Extension.

Example: This will now accept mail for user-sales-john@domain.com, user-sales-amy@domain.com, and any other variation starting with user-sales-.

 

Remove an extension

  • Log in to your User Panel. Use your full email address and password to sign in.
