When the Mail app on your iPhone starts misbehaving — new messages never arrive, sending gets stuck in the Outbox, or the app crashes on launch — the first instinct is to look for a “reset” button. Apple doesn’t provide one, but you can achieve the same result with two reliable methods: removing and re-adding your email account, or reinstalling the Mail app entirely. Here is how both work, plus the sync checks that fix most Mail problems without any reset at all.
Method 1: Remove and re-add your email account
This is the gentlest reset. It clears the account’s local settings and cached data while leaving everything else untouched:
- Open Settings → Mail → Accounts.
- Tap the account that is causing trouble.
- Tap Delete Account and confirm. Don’t worry: this removes the account from your iPhone only — your emails stay on the provider’s server.
- Go back to Mail → Accounts → Add Account, choose your provider, and sign in again.
- Make sure Mail sync is enabled for the re-added account.
Important: know your email password before you delete the account — you’ll need it to sign back in. If your provider uses two-factor authentication, have your second factor handy too.
Method 2: Reinstall the Mail app for a full reset
If re-adding the account doesn’t help, reinstalling Mail wipes the app back to factory defaults:
- Open Settings → General → iPhone Storage.
- Find Mail in the list and tap it.
- Tap Delete App and confirm.
- Open the App Store, search for “Mail”, and reinstall Apple’s Mail app.
- Open Mail and add your accounts fresh.
Mail is one of the built-in iPhone apps you can safely delete and reinstall — iOS treats it like any App Store app. Troubleshooting roundups on MakeUseOf list reinstallation as the most reliable fix for a corrupted Mail installation.
Fix sync issues without a full reset
Often the app itself is fine — it is the sync schedule that’s wrong:
- Go to Settings → Mail → Accounts → Fetch New Data.
- Make sure Push is enabled, or set Fetch to the most frequent schedule for accounts that don’t support Push.
- Restart your iPhone (hold the side button and a volume button, then slide to power off).
- Install any pending iOS updates under Settings → General → Software Update.
- As a last resort, reset network settings via Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings — you’ll need to rejoin Wi-Fi networks afterward.
Apple documents these sync settings in Apple Support’s Mail on iPhone guide, and 9to5Mac regularly covers Mail bugs fixed by iOS updates, so keeping iOS current genuinely matters.
Once Mail behaves again, you can also mute Mail notifications for specific contacts in macOS to keep the desktop side of your inbox quiet too.
If it still doesn’t work
If Mail still misbehaves after a reinstall, the problem is probably on the provider’s side: check your email provider’s status page, verify your account isn’t locked, and try the provider’s own app (like Gmail or Outlook) to see whether the issue follows you there. If the provider’s app works fine but Apple’s Mail doesn’t, contact Apple Support — and make sure you’re not behind a VPN or content filter blocking mail ports.
FAQ
Will deleting my email account erase my emails?
No. Deleting an account from Settings → Mail → Accounts removes it from your iPhone only. Your messages remain on the provider’s server and reappear when you add the account back — as long as you use IMAP or Exchange, which virtually all modern providers do.
Do I need to reset all iPhone settings to fix Mail?
Almost never. Re-adding the account or reinstalling Mail resolves the vast majority of issues. Resetting all settings is a sledgehammer that wipes Wi-Fi passwords and preferences with no added benefit in most Mail cases.
Conclusion
There is no single “reset Mail” button on iPhone, but you don’t need one: remove and re-add the faulty account for a quick settings reset, or delete and reinstall the Mail app for a complete fresh start. Pair that with correct Fetch/Push settings and an up-to-date iOS, and the Mail app should be back to delivering your messages reliably.
