1 Customize iMessage Settings

Open the Settings app and select Messages to enable/disable iMessage, and change your messaging settings. You can choose whether or not a contact photo is displayed, enable read receipts for all messages, and choose to forward text messages to other devices.
Enable “Send as SMS” if you’d like messages to send as text messages when iMessage is unavailable. If you want to be able to send subjects with your messages you can enable Show Subject Field. And Character Count will display how many characters you’ve typed in a new message.
You can even setup when messages and audio files expire; and, you can filter unknown senders so you’re only notified of messages from contacts.
Final Thoughts
iMessage is a fantastic messaging platform. It would be nice to see it come to Android and Windows in the future to allow more people to use the service. Currently Apple is working on bringing Business Chat to iMessage in a future iOS 11 update.
Business Chat will let users and organizations interact through iMessage and will integrate with other customer support services. Initial businesses will include Hilton, Lowe’s, Wells Fargo, and Discover.
If you’re not already using all of the features of iMessage, today is a great day to start. Use Tapbacks to respond quickly, use stickers to make someone smile, and use effects to say it loud or quiet. iMessage lets your text messages speak for themselves.
