Fix 1: Enable Mobile Service for the Mail App

Are you trying to fetch new emails on cellular data? You might not receive new emails if the mobile service toggle is disabled for the Mail app. Head to iPhone settings to enable it.

Open the Settings app, select Mobile Service, and scroll down to enable it for the Mail app.

Fix 2: Adjust Mail Fetch Settings

To avoid missing emails in the Mail app, you must push emails from the server when possible. If Push is unavailable for your email provider (e.g. Gmail), switch to Fetch and increase its frequency.

Step 1: Open iPhone settings, select Mail, and tap Accounts.

Step 2: Select Fetch New Data, enable Push (if unavailable, pick Fetch) for your email account, and set the Fetch frequency to Every 15 Minutes.

Fix 3: Correct Device Date and Time

If your iPhone has an incorrect date and time, the Mail app may fail to communicate with the server to show new emails. Correct your device date and time and reopen the Mail app.

Select General under iPhone Settings, tap Date & Time, and turn on the toggle for Set Automatically.

Fix 4: Disable Mail Privacy Protection

Mail Privacy Protection safeguards your privacy by hiding your IP address so email senders can’t track your online activity. However, an issue with it malfunctions the Mail app and halts fetching new emails. Disable it under Mail settings to restore its normal functioning.

Step 1: Select Mail under iPhone Settings and tap Privacy Protection.

Step 2: Disable the Protect Mail Activity toggle.

Fix 5: Delete and Re-Add Your Account

Lastly, delete and re-add your email account to the Mail app to fix account authentication issues that are preventing you from viewing new emails.

Step 1: Open the Settings app, select Mail, and tap Accounts.

Step 2: Select your configured mail account and tap Delete Account. Tap Delete Account again to confirm.

Step 3: To re-add it, select Add Account on the previous page, pick your desired mail service, and type your credentials to log back in.
