text messages on iphone

Hello DB7564,

Thanks for getting back to us with those additional details. From what you're describing, it looks like you are referring to the mention feature when sending a message on your iPhone. For more information, check this out:

How to use mentions

1. Open a Messages conversation.

2. Type a contact's name, then tap the name when it appears. Or type @ followed by their name.

Depending on your contact's settings, a mention can notify them even if they've muted the conversation. To change this notification setting, go to Settings > Messages, then turn Notify Me on or off.

 Reply to specific messages on your iPhone, iPad, and iPod touch

If that's not what you're experiencing, let us know more about this behavior, and we'll do our best to assist.

Cheers.
