Currently, in order for the sender's name to appear in an email to the recipient, a signature must be used. It would be nice to pull the sender's name from their Front profile or allow it to be set elsewhere without the need to create a signature. Alternatively, allow for no text to be added to the signature text field.
The option to set a signature with no text would work as an alternative. It's not ok to need to set a signature with something in it in order to set Sender's name....
