How I stop iMessage from one person

ketul130,

Thanks for clarifying.

You can disable "read receipts", so that the sender is not notified that you've read the iMessage. You can do this at Settings > Messages

You can also change message notification settings if you don't want to get notified they have contacted you, such as silencing the message conversation. See Change message notifications on iPhone - Apple Support

That should help.

Take care.

Hello ketul130,

Are you asking how to block a person from sending you messages through iMessage? If so, this article explains that process: Block, filter, and report messages on iPhone - Apple Support. Follow this guidance to block a specific number:

"Block messages from a specific person or phone number

When you block a specific contact or phone number, messages from that person or number aren’t delivered. (The person sending the message doesn’t know that their message was blocked.)

1. Open the Messages app  on your iPhone.
2. In a Messages conversation, tap the name or number at the top of the conversation.
3. Tap Info , scroll down, then tap Block this Caller.

Tip: Instead of blocking all the senders in a group conversation, you can simply leave it or stop its notifications.

If you’re still having trouble with unwanted messages, see the Apple Support article Block phone numbers, contacts, and emails on your iPhone or iPad."

We hope this helps. Let us know if we can assist with anything else at all. Take care.
