If you have users that you want to manage in Signitic but who are not from Google Worspkace or Microsoft 365 email managers, you can add them manually directly on your account.
Warning: Users added manually on Signitic will not be able to have their signatures updated on webmails (Gmail & Outlook Web) but only on heavy clients using the Signitic agent.
The theory is over, now it's time to practice. To start, go to Users.
Click on Add users at the top right and then Add manually :
Enter the primary information of your users and Confirm.
You should now find your created users in your list and then go to edit their informations and group.
