How do I add favorites to iMessage

Hello, maureen107.

Thank you for posting in Apple Support Communities. We understand that you’re wanting to add favorite contacts to your Messages, and we want to help.

• If you’re referring to pinning conversations for important contacts at the top, the “Pin important messages” section of the article you referenced will help.

• Otherwise, you can choose different contact methods when you add a Favorite in your Contacts app. For example, when you tap “Add to Favorites” you can choose between Message, Call, and FaceTime.
