If you want to stop your iPhone from sending messages without blocking, there are a few things you can do.

  1. Open the Settings app on your iPhone and scroll down to Messages. Tap on the message sender and then tap Block Contact. This will stop any future messages from that person from being sent to your iPhone.
  2. If you want to stop all messages from a certain person, go to their profile page and tap on the message icon next to their name. This will open up their message history and you can then block them by tapping on the Block button next to their name.
  3. If you want to stop specific types of messages, such as text or iMessages, open the Settings app again and tap on Messages under Cellular & Data. Under Message Types, you can select which types of messages you would like to disable. ..
