How to create or edit your individual signatures
Signatures in Front are associated with users. Your signature(s) will follow you from channel to channel (both individual and team), as you reply to messages you're working on.
Go into your Settings and select My signatures.
Click Add a signature to create a new signature, or select a signature from your list that you'd like to edit.
The first field is where you set the Name of your signature. The name will not appear anywhere on the recipient's end. The next field is the Sender Info. This is where you set what will appear in the header of emails you send. Finally, the large text box is for the signature itself. Here, you can customize the formatting of your signature, and add images or use HTML as well.
Click back into the signature you just created or edited, then select Channels, and toggle whether the signature is visible in all channels. Step 6 (optional)
If you turn the toggle off, use the checkboxes to choose which channel(s) you want this signature to appear in.
How to switch between signatures
You can switch between signatures while you're composing a message. Click the arrows to the right of your signature and a dropdown of your options will appear.
