How to add custom message responses to your Apple Watch

With watchOS 2, Apple added some features to the Mail app that make it possible for you to actually respond to email right from Apple Watch. Similar to responding to text messages on Apple Watch, users can now use voice dictation, send an emoji, or respond with a preset default reply.
Additionally, Facebook recently updated its Messenger app to work on Apple Watch. So, now you can read and reply to chats with Facebook contacts.

Apple provides room for about 20 default replies for Messages and about a dozen for Mail. Facebook provides six. You are not confined to the premade responses, however, and you can customize them to say whatever you’d like.
We’ve got a quick tutorial explaining how to customize your quick responses to fit your personality. The steps are very similar for customizing default responses in all three apps.

Tap a premade response and replace it with your own.
