Mail not working after update iOS 18.1.1

After updating iOS to 18.1.1, the mail app is not working. It is totally malfunction and can’t receive nor send email. Start the mail app, it just pops up a white screen. I have tried to offload the app and reinstall it. It’s the same. When I hard reset the phone, it can pop up the mail account list but freezes. How do I fix it?

iPhone 14 Pro Max, iOS 18

Solution: Go to Settings. Click your name at the top to access your Apple Account. Look for a notice at the top of your Apple Account page that asks you to accept the new terms and conditions for Mail. Accept the new terms.


Context: Apple has introduced new AI features with Mail that requires the terms be accepted and it is causing all sorts of issues with the Mail app until you accept the new terms. I was having issues with Search, Sending mail, and indexing had also halted. Once I accepted these terms, everything worked perfectly again.


One more thing: Go to Settings > iCloud. Check the iCloud backup status. Mine had been halted, so it wasn't backing up. You may need to click Back Up Now after you've accepted the terms.


My usage situation: iPhone, Mac Mail user, iCloud account, Mac email account only. The only issue I had was on the iPhone Mail app (Mail was working fine on my Mac desktop and laptops). If this isn't your situation, then your mail issue may be different to mine.


Hope this helps someone!

Lost email has absolutely nothing to do with the updates to mail; lost email is a completely different problem. The update only changes the way email in the email database is displayed, it doesn’t remove any content.


These 2 steps will return the Mail app to the way it previously worked:


To remove the icons in the list view:

  • Open Settings
  • Tap Apps
  • Tap Mail
  • Turn off Show Contact Photos
  • Optionally, turn off Summarize Message Previews

To turn off Categories:

  • Open the Mail app
  • Tap on an inbox
  • Tap on ⋯⃝ in the upper right 
  • Tap to check List View

I know that, but I don’t want to make such a backup because it’s already more than 500GB. Then I need to find a drive to store the data first. Moreover, I’ve done this before. After that, all the data are messed up. Some data of some apps are still missing. So it’s rather troublesome. Are there any methods to make it work? Or do I downgrade the iOS to 17? Or are there methods to reinstall the mail app only?

Whenever I try to manage messages, the sheet menu will not stay visible.


if I open a mailbox and select a couple of messages, then I tap "Move" to move those emails to a subfolder, or even trying to delete multiple emails...


the sheet menu opens and closes immediately. Before I can select an action.


This 18.1.1 update has caused major problems with organizing emails in just a few days.

So I did the upgrade late last week. Just happened to notice today that my recent sent emails aren’t showing up. Then I saw that all of the emails are marked as being sent from a person on my blocked list. The blocked list on my iPad shows that it’s my own email that is blocked! But I don’t see a way to change that on the iPad. However, if I go to the Gmail App….and go the blocked people….there aren’t any blocked people and the sent mail does not show the sent mails as blocked. I have no idea what to do about this.

One of my gmail accounts is not receiving emails on the iphone since update Thursday night. The second is. Has anyone found a solution? I have switched on and off many times, gone into settings and checked everything I was asked to check by Apple support and it still doesn't receive or send visibly - I received test email on my mac which receives all email as ever. Just not iphone since update. Any solutions?

I did online support and was told something was wrong with the phone. I went to an Apple Store under their advisement and they had me delete my mail account and reinstall and now I’ve lost all emails and it still won’t connect. I was told to go home and back home the phone then do a full restore to factory then reinstall the back up. Still nothing and now my iPhone XR is acting up too. I can’t access email from any iPhone now
