Hi lmfarmer,
We understand multiple people are receiving the same message from you. We're happy to offer some guidance.
This would likely mean you have multiple people in the message thread instead of just one. You'll want to look in the Messages app at the thread you're sending messages in. At the top it should just have one persons name or phone number. If there are multiple names/numbers listed at the top, then everyone listed there will receive the message you're sending.
Also if you're referring to the "Group Messaging" setting in Settings > Messages, turning that off doesn't stop group messages, it just alters the way they appear.
That setting is specifically for messages that include someone without an iPhone (messages going through your carriers SMS service versus Apple's iMessage service). When you have that setting turned on, if someone places you in a group message with someone that doesn't have an iPhone, the messages you receive will thread together so it's under one message like if it was going through Apple's iMessage service. When you have that setting turned off, the messages will not thread together, and you'll receive individual messages from everyone in the group.
So for example, say "john" creates a group message on his phone and includes you and "joe" (who isn't using an iPhone, so the messages all go through SMS). Whatever messages john and joe send in that group message will come to you as individual messages instead of threaded together because you have the Group Messaging setting turned off.
Send a group text message on your iPhone, iPad, or iPod touch
Hope this helps. Cheers!
