How to Fix Gmail Not Sending or Receiving Emails

Gmail’s reliability as an email service can occasionally falter, leaving users frustrated when messages fail to send or arrive. This guide explores effective troubleshooting methods to get your Gmail account back on track.

Check Your Internet Connection

A stable internet connection is crucial for Gmail to function properly. Before diving into more complex solutions:

Step 1: Open a new browser tab and try loading a different website.
Step 2: If other sites load slowly or not at all, restart your router or contact your internet service provider.
Step 3: Once your connection is stable, return to Gmail and attempt to send or receive emails again.

Clear Browser Cache and Cookies

Accumulated browser data can sometimes interfere with Gmail’s functionality:

Step 1: Open your browser settings.
Step 2: Navigate to the privacy or history section.
Step 3: Select the option to clear browsing data.
Step 4: Ensure “Cached images and files” and “Cookies and other site data” are checked.
Step 5: Choose a time range of “All time” for a thorough cleanup.
Step 6: Click “Clear data” and restart your browser.

Check Gmail Storage Space

When your Google account runs out of storage, it can prevent new emails from arriving:

Step 1: Visit https://one.google.com/storage
Step 2: Review your storage usage across Gmail, Google Drive, and Google Photos.
Step 3: If you’re close to or at capacity, delete unnecessary emails and files or consider upgrading your storage plan.

Review Gmail Filters and Forwarding

Incorrectly configured filters or forwarding settings can misdirect your emails:

Check Filters

Step 1: In Gmail, click the gear icon and select “See all settings.”
Step 2: Go to the “Filters and Blocked Addresses” tab.
Step 3: Review existing filters and delete or modify any that might be affecting your email delivery.

Verify Forwarding Settings

Step 1: In Gmail settings, navigate to the “Forwarding and POP/IMAP” tab.
Step 2: Ensure forwarding is disabled or set up correctly if you intentionally use this feature.

Examine Spam and Trash Folders

Sometimes, important emails can be mistakenly classified as spam:

Step 1: Check your Spam folder for any missing emails.
Step 2: If you find legitimate emails there, mark them as “Not spam” to train Gmail’s filters.
Step 3: Also review your Trash folder for accidentally deleted messages.

Verify Account Security

Security issues can sometimes prevent normal email functionality:

Step 1: Visit https://myaccount.google.com/security
Step 2: Review recent security events and ensure there’s no suspicious activity.
Step 3: If you notice any unauthorized access, change your password immediately and enable two-factor authentication if it’s not already active.

Check IMAP and POP Settings

If you use an email client to access Gmail, incorrect settings can cause issues:

Step 1: In Gmail settings, go to the “Forwarding and POP/IMAP” tab.
Step 2: Ensure IMAP is enabled if you use it.
Step 3: If you use POP, verify it’s correctly configured.
Step 4: Double-check that your email client’s settings match Gmail’s recommended configuration.

Temporarily Disable Antivirus Software

In rare cases, overzealous antivirus programs can interfere with email traffic:

Step 1: Temporarily disable your antivirus software’s email scanning feature.
Step 2: Test sending and receiving emails in Gmail.
Step 3: If this resolves the issue, consider adjusting your antivirus settings or switching to a different security solution.


By systematically working through these troubleshooting steps, you should be able to resolve most Gmail sending and receiving issues. If problems persist, contacting Google Support or consulting with an IT professional may be necessary for more complex problems.
