User Specific Email Templates
When emailing sales records and related dockets, you can set up a global default email template (set up via Setup > Preferences > Email Templates & Settings), or each user can optionally have their own custom email template that is personalised for them.
Assigning the template
From the main menu strip at the top, go to Setup > Preferences > Users.
Click a user to edit their basic details.
Select an email template for this user from the Email Template dropdown.
Click Save Changes.
