One contact, two iMessage threads?

I've got one contact on my iPhone that has a mobile phone number and an email address, both of which are associated with her own iMessage account. When I send her an iMessage, if I choose the mobile phone number, my iMessage goes into one thread; and if I select the email then the iMessage goes into a different thread. Both are iMessage, neither are SMS. Is this the way iMessage is supposed to work? It sure is darned annoying.

iPhone 6, iOS 10.2.1, null

Yes and no. You are essentially sending to two different accounts even if it's the same person. Think of it this way. One device is the mobile number and another device is the email. Not saying that is the scenario but that is how iMessage works. It picks up on who you are trying to send it to.


If you have John with phone number 555-555-5555 and you also have john@example.com under that same contact. It's still the same person but those two ID's if you will are separate ways of reaching out to him so on your end it would show up as two different threads. Does that make sense?

It happens to me as well. I think iMessages splits conversation by used address(es) and does not care whether it is SMS or iMessage. Any address (whether it is a number or an email) or their combinations create new thread. Also if you send SMS to multiple contacts, it pretends creating a multi-chat (like for iMessages), but replies comes in separate threads as single message.


I don't know whether it is useful, but that's how it works.

Well, at least it's helpful to know that this is the way Apple intends for iMessage to work. And since we know that Apple believes that it always knows better than its customers how things should work, it's pointless for me to observe that the way this works on iMessage is absurd. I get your comparison to "two different email addresses," but I would argue that the situation here is actually akin to one email address and one alias that points to the first email address. But Apple knows better ....

Kind of makes sense, kind of doesn't! On my friend's phone, her iMessage "Send & Receive" settings say "You can be reached by iMessage at" and then it lists the phone number and the email address. So iMessage knows that these are just two different ways to reach the same user, and I don't get why iMessage would put the messages in different threads. Y'know?
