Fix 01: Check Email App Settings

The first step to troubleshoot the email syncing issue is to check the settings of your email app. This is because sync options should be correctly configured to ensure that your emails are being updated in real-time automatically.

Fix 02: Sync Mails Manually (Only Once)

Temporary glitches in the email apps also cause emails to not sync on your Samsung Galaxy S21. A simple solution to this issue is manually syncing your emails. 

This process forces the app to re-establish its connection with the email server and resolve any glitches that prevent automatic syncing. Once you’ve manually synced your emails, they should continue to sync automatically thereafter.

Here’s how you can manually sync your emails in the Gmail and Samsung Email apps (The steps for other email apps will be similar):

Sync Email Manually for Gmail:

  1. Open the Gmail app.
  2. Swipe down refresh the mailbox and sync emails manually.

Sync Email Manually for Samsung Email:

  1. Open the Samsung Email app.
  2. Tap on the three horizontal lines at the top left corner to open the menu.
  3. Tap on Manage accounts.
  4. Select the email account you’re having issues with.
  5. Tap on Sync schedule.
  6. Ensure that Auto (when received) is selected. If it isn’t, tap on it to enable automatic syncing.

Fix 03: Re-Add the Account to the Email

Re-adding the account to the email app is a tried-and-true method that has proven to be working for many Samsung Galaxy users experiencing sync issues. 

The logic behind this fix is simple – it gives the app a new start with your account, which can resolve any underlying bugs or glitches preventing your emails from syncing properly.

Here’s how you can re-add your account on both the Gmail and Samsung Email apps:

For Gmail:

  1. Open the Gmail app.
  2. Tap on your profile picture.
  3. Tap on Manage accounts on this device.
Gmail - manage accounts on this device
  1. Find the account that’s not syncing and tap on Remove account.
Remove selected google account
  1. Confirm your decision.
  2. Once the account has been removed, tap on Add another account and follow the on-screen instructions to re-add your account.

For Samsung Email:

  1. Open the Samsung Email.
  2. Go to Settings.
  3. Find the account that’s not syncing and tap on it.
  4. Tap on Remove.
Remove samsung email account
  1. Confirm.
  2. After removing the account, re-add it from the main setting menu.

Fix 04: Check Email Notifications

If notifications are turned off, you won’t see the new emails even if the device syncs them correctly.

This should be checked in two areas: within the email app’s settings and in the system settings of your Samsung Galaxy S21. For each email app, there is an option to enable notifications, and you should ensure that this is turned on.

Let’s start with the Gmail app:

  1. Open the Gmail app.
  2. Go to its Settings.
Gmail settings
  1. Select the email account you’re having issues with.
  2. Tap on Notifications and ensure that it’s set to All.

For system settings:

  1. Go to Settings.
  2. Tap on Apps.
  3. Find and tap on Gmail.
  4. Tap on Notifications.

  1. Ensure the Show Notifications toggle is turned on.

Fix 05: Clear Email App Cache

Clearing the cache of your email app can also fix email sync problems. This is because, over time, this cache can become old or corrupted and cause performance issues.

Note: Clearing the cache will not delete your emails or account. It simply clears temporary files causing issues.

Here’s how to clear the cache for the Gmail app:

  1. Go to Settings.
  2. Tap on Apps.
  3. Tap on Gmail.
  4. Go to Storage.

Fix 06: Update Email App

If your email app is out of date, it might not sync properly with the server. Updating your email app can resolve syncing issues, as developers frequently release updates to fix bugs, improve performance, and add new features.

Here’s how you can update your email app (We take Gmail as an example):

  1. Open Google Play Store.
  2. Tap on the search bar and type Gmail (or the app you are having issues with).
  3. Tap on the app from the search result.

  1. Tap on Update.
