iMessage shows a contact's email instead of their phone number

Someone texts you from their phone, but the thread shows their email address — or they show up twice in a group chat. Two-minute fix on your iPhone. No action needed on their end.

Requested by a reader. Tested on iOS 26.6.1, August 2026, on a real split contact.

What's going on

iMessage can send from a phone number or from an email address tied to the sender's Apple Account. If your Contacts card for that person only has their phone number, iOS has no way to connect the email to them. So it treats the email as a stranger and starts a separate thread — or, in a group chat, lists the same person twice.

The fix is to put the email on their contact card so Messages knows it's the same person.

The fix (on your iPhone)

1. Copy the email address from the thread

   Open the Messages thread that's showing the email. Tap the name at the top, then tap Info. The email address is listed there. Touch and hold it to copy. In a group chat, tap the group name, then the duplicate person, to find it.

2. Open Contacts and find the person

   Open the Contacts app and tap the contact whose messages are split.

3. Tap Edit

   Top-right corner.

4. Add the email and label it iCloud

   Scroll to the email section, tap add email, paste the address, then tap the label and choose iCloud. Messages matches on the address itself, but iCloud is the label I tested with and it makes clear later why it's there.

5. Tap Done

   Top-right corner.

6. Delete the duplicate contact, if there is one

   Search Contacts for the email address. If it turns up a second card — often a bare one with just the email, sometimes created from a "Maybe:" suggestion — delete it. Two cards holding the same address is a common reason the fix doesn't take.

   Duplicates also come from having more than one contact source on the phone. Tap Lists in the top-left of Contacts: if you see iCloud alongside Gmail, Outlook, Exchange, or Yahoo, the same person can exist in two of them with different details, and Messages may be matching the email against the wrong one. Pick one source to be the real card, put the number and email on it, and delete or clean up the copy in the other account.

7. Close and reopen Messages

   From the Home Screen, swipe up from the bottom edge and, without lifting your finger, curve to the right — one motion, like drawing an upside-down L. That opens the app switcher. Find the Messages card and flick it up off the top of the screen to close it. (On an iPhone with a Home button, double-press Home instead.) Then reopen Messages. The thread now shows their name, and the duplicate in group chats collapses into one person.

Stopping it for good (on their iPhone)

The fix above handles it on your side. The reason it happened is that their iPhone is set to start new conversations from their email instead of their phone number. If they change that, it won't happen to anyone else they message either:

Settings → Apps → Messages → Send & Receive → under Start New Conversations From, tap their phone number.

On older iOS versions, skip the Apps step. Existing threads they started from the email stay on the email; only new conversations use the number.

Their other devices count too. An iPad or Mac has its own copy of this setting, and an iPad without cellular usually defaults to the email address. If they reply from an iPad, Mac, or Apple Watch, the message can come from the email even after the iPhone is fixed, and the split comes back. On iPad it's the same Settings path; on Mac it's Messages → Settings → iMessage → Start new conversations from. The Watch normally follows the iPhone, but it's worth checking if the problem persists.
