In Messages, swipe right on a conversation and tap the unread control. The conversation returns to an unread state so you can find it later. This is a reminder for you; it does not unsend a read receipt that the other person has already received.
Mark one conversation unread
- Open Messages and go to the conversation list.
- Swipe right on the conversation you want to revisit.
- Tap Unread or the unread icon that appears.
You can also drag the conversation to the right to apply the action, depending on the iOS version. The unread indicator appears beside the thread. Opening the conversation again marks it read, so leave it closed until you are ready to respond.
Mark several conversations unread
On the conversation list, tap Edit, then Select Messages. Select the threads and tap Unread. If you use message filters, make sure you are in the list containing the threads you want. This is useful when you have several replies to handle after a busy period.
Find or clear unread threads
If Filters is shown, open it and choose Unread Messages to see conversations still marked unread. To clear unread indicators in bulk, use Edit > Select Messages > Read All when that action is available. The filter and button placement can vary with iOS version and the current Messages layout.
Choose unread or another reminder
Marking a conversation unread is useful when you have read it but cannot reply yet. It puts an unread marker back in your conversation list; it does not schedule a notification for later. If you need a timed prompt, set a reminder in a reminders app and include the person's name. If the thread is one you need to find often, pinning it may be more useful than repeatedly changing its read state. Apple documents pinning and unread status as separate ways to organize Messages.
Confirm that the action worked
Return to the conversation list immediately after the swipe or multi-select action. The thread should display its unread marker, and it should appear when you apply the Unread filter. If it does not, you may have swiped the wrong thread or reopened it after marking it unread. Repeat the action from the list and do not enter the thread again until you are ready to handle it. The filter itself does not change a thread's state; it only changes which threads you see.
If you cannot find the conversation
Clear any active Unread filter so both read and unread threads are visible. Search for the contact or a distinctive phrase in Messages, then return to the list and mark the correct thread unread. Check any other message filters you use; a conversation that is outside the current filtered view cannot be selected there. If the conversation was deleted, marking it unread is not a recovery method. Look in Recently Deleted only if you actually removed the conversation.
Read receipts and unread markers are different
The unread marker is a personal organization tool. A read receipt, when enabled and supported for that conversation, can tell a sender that you opened their message. Marking the thread unread afterward does not take back a receipt already sent. If your goal is to change whether future receipts are sent, use the Messages read-receipt setting for the relevant conversation or account. Do not treat the unread swipe as a privacy control.
Frequently asked questions
Can I mark just one message bubble unread? Apple's documented action is for a conversation in the conversation list. It is not a way to assign a separate unread state to one bubble in the thread.
Can I mark several threads at once? Yes. Use Edit > Select Messages, select the conversations, then Unread. Check your selection before applying it so you do not change unrelated threads.
How do I remove all unread markers? Apple documents Edit > Select Messages > Read All. Use it when you have caught up and want a clean unread list. This changes your organization state; it does not delete any conversations.
Marking a message unread does not restore a deleted conversation. For retention settings, see how to keep old iPhone messages. For a different notification issue, see why a bell or moon appears beside a text conversation.
Apple's Messages guide documents the unread action and unread filter.
Marking a conversation unread creates a reminder for you. When you return to it, you can react with a Tapback to acknowledge a particular bubble, or forward selected messages to share their content with someone else.
