Warning: (Mac Users) The Safari Browser Cannot Be Used

To properly support an HTML email signature, the Safari web browser cannot be used for your signature installation. The formatting will turn out wrong if Safari is used to open and copy the signature. Note that using an alternative browser is temporary. Once the signature has been installed you may return to using Safari as your default browser.

Manual Install - Part 1 - Copying Your Signature to Your Clipboard

Note: If you don’t currently have your signature open in a browser tab, display it now:


In the tab with your signature, press Ctrl-A then Ctrl-C - this will select your entire signature and then copy it to your clipboard.

Note: Mac users will use Command-A and Command-C.

2. Pull down to OPTIONS (see below):

3. Now choose “Email Signature” from the left menu (found under Mail and then Layout):

The next time you go to compose a message (or reply to one) your signature or business card will automatically appear.
