How to Schedule an iMessage on iPhone: A Step-by-Step Setup Guide

How to schedule an iMessage on iPhone comes down to one built-in feature: Send Later, available in Messages on iOS 18 and later.

It lets you pick a message now and have it sent automatically up to 14 days ahead, without needing a third-party app.

What You Need Before You Start

Before the option even shows up, a couple of things need to be true. Skip this part and you'll end up confused about why "Send Later" isn't appearing at all.

iOS Requirement

Scheduling is built into Messages starting with iOS 18, according to TechCrunch, which covered the feature as one of the more practical additions Apple introduced alongside RCS support.

If your phone is running an older version, the option simply won't be there  no error message, it just doesn't exist yet.

The Recipient Must Be Using iMessage

This only works inside iMessage conversations, meaning the thread needs to show blue bubbles.

Green-bubble SMS or RCS threads don't support scheduling. In practice, this trips people up more than anything else someone assumes the feature is broken when really, the contact just isn't on iMessage.

How to Schedule an iMessage (Step-by-Step)

How to Schedule an iMessage in 4 Steps

Here's the exact sequence, from opening Messages to confirming the scheduled send.

Step 1 – Open Messages and Select a Conversation

Open an existing iMessage thread, or start a new one with a contact you know uses iMessage.

Step 2 – Tap the Plus Icon and Choose Send Later

Next to the text field, tap the "+" icon. A menu appears select "Send Later" from the list.

Step 3 – Set the Date and Time

Tap the time field to open the scheduler. Choose when the message should go out. You can schedule up to 14 days in advance, not further than that.

Step 4 – Type Your Message and Confirm

Write your message as usual, then tap the send arrow. That's it the message is now scheduled, not sent.

What a Scheduled Message Looks Like

Once scheduled, the message bubble shows a dashed border instead of a solid one, and the scheduled time appears above it in the conversation. It stays that way until it's actually delivered.

What Happens After You Schedule a Message

Delivery Works Even if Your iPhone Is Offline

Interestingly, the message will still send at the scheduled time even if your phone is powered off or has no signal at that exact moment, since it's queued on Apple's servers rather than sitting locally on your device.

How Scheduled Messages Are Stored

Apple stores scheduled messages in encrypted form on its servers until they're sent. This lines up with how iMessage handles regular messages too as described on Wikipedia, the service uses end-to-end encryption so only the sender and recipient can read a conversation.

Once delivered, the scheduled message is removed from Apple's servers it isn't kept there afterward.

Does the Recipient Know It Was Scheduled?

No. The person receiving it sees a normal iMessage with no indication it was set up in advance.

How to Change, Edit, or Delete a Scheduled iMessage

Reschedule the Send Time

Open the conversation, tap "Edit" beside the scheduled date, then choose a new time before it sends.

Edit the Message Content

Touch and hold the scheduled bubble, tap "Edit," make your changes, then confirm.

Delete or Cancel a Scheduled Message

Touch and hold the message, then tap "Delete." This cancels it — the recipient never sees it.

You Must Be Online to Make Changes

Rescheduling, editing, or deleting all require an internet connection, since those actions communicate with Apple's servers. If you're offline, you'll need to wait until you're connected again.

Common Issues When Scheduling an iMessage

"Send Later" Option Is Missing or Greyed Out

This usually means the conversation isn't iMessage (it's SMS or RCS instead), or the device is running an iOS version older than 18. There's no workaround within the Messages app itself for either case.

Scheduling in Group Chats

Send Later is generally available in group iMessage threads as well, provided every participant is reachable via iMessage.

If even one person in the group is on SMS, the whole thread may default back to standard texting, which disables scheduling for that conversation.

Managing Scheduled Messages Across iPhone, iPad, and Mac

Because scheduled messages sync through iCloud and your Apple ID, a message scheduled on iPhone can typically be seen and in some cases managed from Messages on iPad or Mac, as long as those devices are signed into the same account and messages-in-iCloud is turned on.

Teams that rely on Messages for coordinating reminders across multiple Apple devices commonly report this cross-device visibility as one of the more useful side effects of scheduling.

Scheduling on Older iPhones (iOS 13–17)

Why Native Scheduling Isn't Available

Send Later simply doesn't exist before iOS 18. There's no hidden setting to enable it the feature wasn't part of Messages on earlier versions.

Shortcuts as a Workaround

On older iOS versions, some people use the Shortcuts app to build a personal automation that sends a message at a set time.

It's not the same as native scheduling it requires more setup, and it's built around automations rather than a simple in-conversation option but it's the closest workaround available without upgrading iOS.

Conclusion

Scheduling an iMessage on iPhone takes a few taps once you're on iOS 18: open Messages, select Send Later, set a time, and send.

It works offline, keeps messages encrypted until delivery, and can be edited or canceled anytime before it sends.

FAQs

Can you schedule an iMessage in a group chat?

Generally yes, as long as everyone in the group is reachable through iMessage. If the group includes SMS-only contacts, scheduling may not be available.

Is there a limit to how many messages you can schedule at once?

Apple hasn't publicly specified an exact cap, so this isn't something that can be stated with certainty either way.

Can you schedule a message from Mac or iPad?

Scheduled messages set on iPhone can often be viewed on other Apple devices signed into the same Apple ID, though the scheduling action itself is documented specifically for iPhone.

What happens if you delete the conversation before the scheduled time?

Deleting the conversation removes the scheduled message along with it, so it won't be sent.

Does scheduling an iMessage cost anything extra?

No. It's a built-in feature of the Messages app and doesn't require a subscription or added charge.
