The default sender name is the name on your account. If you prefer to show a group name as the card sender (such as XYZ Team or your company name), you can change this by logging in and going to the Account Settings tab. Then click Custom "From" Name from the Settings menu.

You can also customize the sender name for an individual card by entering the name in the Sender Name field on the Card Settings page.

Please note the subject line of the email delivering the card will say "'From name' sent you a GroupGreeting card."
