Within Teamwork, you can use your own site logo in your outbound email notifications.
Note: Using your own site logo in your outbound Teamwork email is available on paid subscriptions.
Click your profile image in the bottom left corner of your site and select Settings from the pop-out menu.
In the settings area, go to the Email subsection where you will see an option to Use Logo in Notifications.
You can choose to toggle this on to show your own site logo on any email sent from your site.
If you choose to toggle this off, Teamwork branding will be used instead.
Note: Enabling this feature only controls which logo is used. You cannot alter the teamwork.com address used to send the notifications.
