Over the past few weeks, iOS and macOS owners have started to notice random calendar events appearing within their Calendar apps, informing them of upcoming “genuine RayBan sales” despite not adding the events themselves. This is actually the latest trick from spammers to get you to part from your hard earned cash, as it seems they’re moving from the standard junk-mail approach. It’s made possible by a loophole in Apple’s iCloud calendar service and allows senders to automatically push calendar alerts to iOS and macOS users without the need for an email address.

The worst part is that by responding to the invite (whether you’re declining it or otherwise) it alerts spammers to the fact that your address is active, and they’ll then send many more your way. While this isn’t convenient, there is a way to secretly decline/delete spam iCloud calendar alerts, and also a way to clock any incoming alerts in the future.

How to secretly decline spam iCloud Calendar alerts

So, you’ve received a spam iCloud Calendar invite but don’t want to let the spammers know your address is active by responding or deleting the calendar invite. What can you do instead? While there is another way to remove the events from your calendar, it is a little long winded – although in the long run, it’s well worth doing. Whatever you do, don’t respond to the spammer!

  1. Go to the Calendar app, tap Calendars > Edit > Add Calendar… in your iCloud calendar list.
  2. Name the Calendar something that’ll stand out from your other calendars. “Delete me” is always a good one to use.
  3. Next, you need to change the category of spam calendar invites to the new calendar you just created. Open the event in question in the Calendar app, tap the “>” on the Calendar bar and select the new calendar.
  4. Repeat this process for all spam calendar events.
  5. Go back to the Calendar list (step 1) and tap “>” next to the new calendar you created. Scroll to the bottom of the Edit Calendar page and tap Delete Calendar

This should remove all the event invites without alerting the spammer to the fact that your email address is active. Now you’ve done that, follow the below how-to to block future alerts from coming through to your calendar.

How to block future iCloud Calendar spam alerts

While blocking future alerts is a simpler process than above, it does require you to access iCloud.com on a PC or Mac web browser.

  1. Head over to icloud.com and log in with your Apple ID and Password.

  1. Navigate to the Calendar web app, click the Settings icon (gear) in the bottom left-hand corner and click Preferences.
  2. Click the Advanced tab and change your invitation setting for Receive event invitations as: from In-app notifications to Email to [insert your email address here.

This should turn off the automatic integration of iCloud Calendar and your Calendar app on your iPhone or iPad, and allow your spam filter to block future spam invitations.
