Log in

Log in via Google, Office 365 or with your connection key.
Create a signature

Open Apple Mail and go to the menu: Mail > Settings > Signatures and create a signature by entering in the signature content your.email@mycompany.com as shown in the screenshot below. The goal here is to only enter your email address in the box; this will allow a connection with the Signitic Agent to be created.
Also, make sure to respect the capitalization present in your email address for proper recognition by the agent. (Example: If during your connection the agent displays your email address as follows: Your.EMAIL@mycompany.com then you must copy exactly the same email address into the signature block in Apple Mail.)
Update your signature
Back in the Signitic client, update your signature by clicking the "Update" button at the bottom of your profile page.

If the signature doesn’t update and/or the loading keeps spinning, open "System Preferences" on your Mac, click on the "Security & Privacy" icon, and check that under "Automation", the boxes related to Signitic are checked.
