iPhone Calendar Spam: How to Remove Fake Event Invites and Stop Them Coming Back

You open your iPhone calendar and there it is: an event you never created, a reminder you never set, a notification for a "deal" or a "security warning" from someone you've never heard of. It feels invasive, and it is.

This is iPhone calendar spam, and it's more common than most people realize. The good news: it's usually a nuisance rather than a sign your phone has been hacked, and you can get rid of it. Here's exactly how.

What is iPhone calendar spam?

iPhone calendar spam happens when unwanted events show up in your Apple Calendar app without your permission. They can look like legitimate appointments, urgent security alerts, or enticing retail offers, but they're junk, and they're meant to get you to tap a link.

There are two main ways this gets onto your phone.

Subscribed calendars are the more common culprit today. You visit a website, a pop-up asks if you want to "subscribe" to a calendar, and you tap OK without thinking. Instantly, that third-party calendar is added to your iPhone and starts filling up with spam events. Apple advises you to make sure you trust the source of a calendar before subscribing.

Direct iCloud invitations are the older method. Spammers send calendar invites to iCloud email addresses the same way they'd send spam email. Depending on your iCloud Calendar settings, those invitations can show up directly in your Calendar app as notifications (Apple).

Neither type usually means your iPhone has been hacked. But both deserve a quick fix.

Why you shouldn't tap anything in the event

Before we get to the removal steps, one rule: don't interact with the spam events. Don't accept. Don't decline. And definitely don't tap any link inside the event.

Here's why. If you accept or decline an iCloud invite, your response can be sent back to the sender, which can show them your account is active and may land you on a list that gets more spam, not less. For events from unknown senders, Apple provides a Report Junk option instead (Apple).

Links inside spam events can lead to phishing sites or prompt you to install a configuration profile. A profile doesn't install itself, though: you have to approve it in Settings (Apple). Treat the events the same way you'd treat a suspicious email: don't click, don't engage, just remove.

How to remove iPhone calendar spam: step by step

Step 1: Unsubscribe from a spam calendar

If the events are coming from a subscribed calendar (usually the case when a whole flood of events appear at once), this is the fastest fix.

1. Open the Calendar app.
2. Tap Calendars at the bottom of the screen.
3. Find a calendar you don't recognize. Tap the info icon (a circle with a lowercase "i") next to it.
4. Tap Delete Calendar or Unsubscribe, then confirm.

These are the steps in Apple's current instructions (iOS 26 or later). On earlier versions of iOS, the button is labeled Delete Calendar, and tapping a spam event may also offer Unsubscribe from this Calendar.

Step 2: Report junk invitations from unknown senders

If the event is an invitation from someone you don't know rather than a subscription, open it, tap Report Junk, then tap Delete and Report Junk. Apple documents this on iOS 26 or later, and the same option is available on iCloud.com (Apple). Apple says the event is then deleted from all devices signed in to the same Apple Account (Apple).

Step 3: Remove it through Settings (if the Calendar app doesn't fix it)

Sometimes the calendar subscription is buried in your account settings. On some versions of iOS, you can find it here.

1. Open Settings.
2. Tap Calendar, then Accounts.
3. Select Subscribed Calendars.
4. Find the unfamiliar calendar, tap it, then tap Delete Account.

Macworld describes the same Calendar-app-first, Settings-second approach. The exact Settings path can vary by iOS version.

Step 4: A fallback for individual invites

If you can't use Report Junk, some security blogs suggest this workaround for individual event invitations (not subscribed calendars). It isn't an Apple-documented procedure, so treat it as a fallback:

1. Open the Calendar app and tap Calendars.
2. Tap Edit, then Add Calendar, create a temporary calendar (name it anything).
3. Open each spam event, tap Calendar, and move it to your new temporary calendar.
4. Go back to the calendar list, tap the info icon next to your temporary calendar, scroll down, and tap Delete Calendar.
5. If you're prompted, choose the option that deletes the events without sending a response.

It takes a few extra taps, but it avoids replying to the sender.

How to stop calendar spam from coming back

Removing existing spam is only half the job. Here's how to make sure it doesn't return.

Change your iCloud invitation setting

This is one of the most effective changes you can make. iCloud Calendar can deliver invitations either as in-app notifications or by email (Apple). Switching to email means invites arrive in your inbox, where you can delete junk and your email provider's spam filter may catch some of it.

You can change it on your iPhone (iOS 17 or later):

1. Open Settings, tap your name, then tap iCloud.
2. Tap Show All, then tap iCloud Calendar.
3. Tap Send & Receive, then under Receiving, choose Email.

You can also change it from a computer or tablet:

1. Go to iCloud.com/calendar.
2. Open the Actions menu at the top of the sidebar, then select Settings, then Account.
3. Choose Receive via Email.

The setting applies to all devices signed in to the same Apple Account with iCloud Calendar turned on (Apple). Legitimate invitations will arrive by email too.

Turn off Calendar notifications (or limit them)

If you'd rather not lose push notifications entirely, you can limit which Calendar notifications come through. Open Settings, tap Notifications, then tap Calendar and review the options for invitations. The exact options vary by iOS version, and silencing alerts doesn't remove spam events from your calendar, so treat this as a supplement to the setting above.

You'll still see invites when you open the Calendar app manually, you just won't get pinged every time one lands.

Be careful what you subscribe to

Subscribed calendar spam often starts with a shady website prompt. If a site you're visiting asks you to subscribe to a calendar, close that prompt and leave the site. Legitimate services rarely need direct access to your calendar.

Be especially cautious with links in text messages. A common tactic is a fake delivery notification, a text claiming your parcel is delayed, with a link to "track it." As Macworld notes, clicking that link can lead to a prompt to subscribe to a spam calendar, and the subscription is only added if you accept it. The package doesn't exist. The calendar that follows does.

Keep your iOS updated

Apple documents Report Junk and Unsubscribe options in Calendar, and which ones you get depends on your iOS version. Staying on the latest iOS version means you get Apple's newest options plus any security patches that close related vulnerabilities.

Go to Settings > General > Software Update to check if you're running the latest version.

What to do if you tapped a link inside a spam event

Mistakes happen. If you did tap a link inside a calendar event, here's what to check.

First, check Settings > General > VPN & Device Management for any configuration profiles you don't recognize. A profile only installs if you approve it in Settings, but if you did, tap the profile and choose Delete Profile (Apple).

Second, if you entered a password or other details on a site you didn't recognize, change that password right away and turn on two-step verification where you can.

Third, review your calendars for any subscriptions you don't recognize and remove them using the steps above.

You're in control here

iPhone calendar spam is irritating, but it's usually not a sign your phone has been taken over. It's a loophole in a convenient feature, calendar sharing, that spammers have learned to exploit. A few targeted steps remove the clutter, and one settings change can stop many invites from reaching your calendar.

The real risk is in the links inside those events. Leave those alone, clean up the subscriptions, and adjust your iCloud invitation settings. Those steps cover most of what people run into.

Conclusion

Calendar spam is annoying, but it's fixable. Unsubscribe from calendars you don't recognize, report junk invitations instead of replying, switch your iCloud invitations to email, and leave links in unexpected events alone.
