Why does Mail keep crashing in iOS 9? Why does Mail crash when I try to compose a new email? How do I stop Mail from randomly crashing?
Like many other stock
iOS apps, Apple’s official Mail client for iOS has had its ups and downs through the years. iOS users have encountered issues with Mail in the past, from the account setup to general use, and while
iOS 9 brought with it a myriad of new features, it also brought with it a handful of Mail app bugs. The bugs seem to affect both iPhones and iPads running various builds of iOS 9 and can cause crashes when trying to compose a new email or during general use. There’s also an issue with unread Mail notifications for emails that have been read.
Don’t worry though, as the Macworld UK team has scoured the internet and found fixes for the most common Mail for iOS bugs and crashes along with possible fixes for each. We’ll be updating this article with new issues and fixes as they arise, so make sure you check back regularly if you’re having issues.

Mail for iPhone keeps crashing: Mail crashes when composing new emails
The introduction of iOS 9 brought with it various changes to Apple’s mobile operating system including the
password protected notes, ‘Night Shift’ mode and split-screen multitasking for iPad users. However along with a selection of new features, iOS 9 brought with it a rather annoying Mail bug which causes a pretty big issue with the Mail app for iPhone and iPad.
The issue first appeared shortly after Apple released iOS 9 back in September 2015, and saw users’ Mail app crashing whenever they tried to compose a new email. While subsequent iOS 9 updates seem to have fixed the issue, that doesn’t help users running iOS 9.0 for whatever reason. We haven’t suffered from the issue ourselves and as such can’t try and fix it, but based on user accounts in various internet forums, we can suggest trying to do the following:
- Force quit the Mail app and restart your iPhone/iPad
- Disable and re-enable each Mail account within the Mail, Contacts, Calendars menu in Settings
- Reinstall iOS 9 on your iPhone/iPad (this is the most extreme option but one that should fix issues if nothing else works)

Mail for iPhone keeps crashing: Mail notifications broken in iOS 9
As well as crashing when trying to compose a new email, iOS 9 brought with it another Mail bug, but this one seems to be focused on users running iOS 9.2. As noted by user garrettra on
Apple’s Support forum at the end of February 2016, the Mail app displays unread notifications even when cleared from the Mail app and Notification Center as well as frequently crashing without loading messages. It seems that others are having the same/similar issues with iOS 9.2, although there is hope – for the unread notification glitch, at least.
Of course, the first step is to hard reset your iPhone or iPad by holding both the Home and Lock buttons until the display turns off. A hard reset is kind of like pulling the plug on your iMac – it’ll have to turn back on and reboot fully, which should clear up most software-based issues. If not, there’s one more thing you can try (apart from resetting your device and restoring from a backup):
- Go to Settings > Mail, Contacts, Calendars and select the Mail account displaying unread messages
- Turn ‘Mail’ to ‘off’ and turn your iPhone off for 30 seconds.
- Turn your iPhone back on and head back to Settings > Mail, Contacts, Calendars and turn mail back on
Hopefully, this should fix any issues with regards to unread notification bugs in iOS 9.2 – while the above helped many users suffering from the glitch, it didn’t work for all. Those who followed the instructions to no avail noted that completely resetting their iDevices and restoring from an old backup seemed to fix the issue.

Mail for iPhone keeps crashing: Mail randomly crashes when being used
Sadly, Mail iOS notification glitches and mail composition crashes aren’t the only issues plaguing Apple’s official iOS 9 Mail client – according to internet forums anyway. Along with faux Mail notifications and the inability to compose an email without the whole app crashing, users are reporting random crashes when using Mail that can’t be attributed to a single action (although this isn’t unique to iOS 9 and has been an issue for years). This makes it harder to reproduce and as such, harder to fix, although there is one possible fix floating around the Internet that users claim is working for them.
Apparently, unlike notification and composition issues, the random crash bug isn’t triggered when accessing any specific menu or performing a specific action and is instead due to ‘problematic’ mail messages usually stored on IMAP servers. That makes the bug extremely hard for Apple to fix as it’s due to messages on your personal account and not the app itself. However, with that being said the issue should be fairly easy to fix (when you know how!):
- Access your email account via a desktop Mail client or web interface (i.e. mail.google.com for Gmail accounts)
- Delete any messages larger than 6MB in size along with any “Mail delivery failure” messages
- Delete your email account from your iOS device and re-add it
If all goes well, your Mail app should no longer crash. Are there other Mail bugs we’ve forgotten to mention here? Let us know in the comments section below and we’ll update this article with new fixes as soon as we find them.
