Why is Gmail not receiving emails?

Gmail not receiving emails can stem from simple connection issues to hidden settings like filters or full storage blocking new messages. This stops important emails from appearing in your inbox, even if they're being sent successfully. Follow these steps to diagnose and fix the problem yourself.

Quick checks (try these first)

1. Verify your internet connection by loading a webpage or using another device; restart your modem or router if needed.
2. Check Gmail's status for outages on the Google Workspace Status Dashboard.
3. Pull down to refresh your inbox in the Gmail app or browser, or restart your device.
4. Search all folders including Spam, Trash, and All Mail for missing emails.
5. Confirm your storage isn't full by checking the bottom of Gmail or Google One storage page.
6. Disable any antivirus or firewall temporarily to test if it's blocking emails.

Internet connection problems

A weak or unstable internet connection prevents your device from syncing with Gmail's servers, making it seem like emails aren't arriving. Even if your Wi-Fi shows connected, the modem might not reach Google's servers properly.

This is one of the most common causes, especially during network glitches or after router restarts.

• Test your connection on multiple devices or networks, like switching to mobile data.
• Restart your modem and router: unplug for 30 seconds, then plug back in.
• Run a speed test or ping Google's servers (try opening mail.google.com on another browser).
• If using a VPN, disable it temporarily as it can interfere with email syncing.

Full Gmail storage

Gmail shares 15GB of free storage across Gmail, Drive, and Photos. When full, new emails bounce back to senders without notifying you, or you see a warning at the top of your inbox.

Old attachments, photos, or forgotten Drive files often push you over the limit unexpectedly.

1. Go to one.google.com/storage to view usage breakdown.
2. In Gmail, search has:attachment larger:10M to find and delete large emails.
3. Empty Trash and Spam folders, as they count toward your quota.
4. Delete old files from Google Drive or Photos via their apps.
5. Consider buying more storage via Google One if you need long-term space.

Filters and rules redirecting emails

Gmail filters automatically sort, label, or forward emails based on rules you set, potentially skipping your inbox entirely. A misplaced filter might send legitimate emails to Spam, Archive, or another folder.

Blocked addresses or overly broad rules from past setups can hide emails without you noticing.

• Open Gmail settings (gear icon) > See all settings > Filters and Blocked Addresses.
• Review each filter: edit or delete any sending emails to wrong folders or marking as read.
• Check Blocked addresses tab and unblock senders if listed mistakenly.
• Test by asking a contact to resend an email after changes.

Forwarding settings issues

Automatic forwarding sends copies elsewhere, leaving your inbox empty. Combined with filters, this hides emails completely.

• In settings > See all settings > Forwarding and POP/IMAP, verify no active forwards.
• Disable any forwards and check if emails now appear.

Emails in Spam or other folders

Gmail's spam filter sometimes flags legitimate emails, especially from new senders or with certain attachments. Messages can also land in categories like Promotions or Social.

Executables, suspicious links, or bulk senders trigger blocks to protect your account.

1. Check the Spam folder and mark good emails as Not Spam.
2. Search in:anywhere or from:sender@example.com in the All Mail view.
3. Review Categories in inbox settings and disable if using tabs.
4. Add important senders to contacts or create filters to whitelist them.

POP/IMAP settings misconfigured

If using Gmail in a third-party app or email client, incorrect POP or IMAP settings prevent proper syncing. Disabled protocols mean emails arrive on servers but not your device.

Wrong ports, servers, or security settings block authentication.

For web Gmail

• Settings > See all settings > Forwarding and POP/IMAP: enable IMAP and POP if needed.
• Save changes and refresh.

For apps like Outlook or Apple Mail

1. In Gmail settings, note IMAP enabled with server imap.gmail.com, port 993, SSL.
2. In your app, update account settings to match: use your full Gmail address.
3. Remove and re-add the account if sync fails.

Sync issues on mobile apps

Mobile Gmail apps need sync enabled and stable connections to fetch emails. Background restrictions or outdated apps cause delays.

On Android or iOS, battery savers can pause syncing.

On Android

1. Open Gmail app > menu > Settings > your account > ensure Sync Gmail is on.
2. Device Settings > Accounts > Google > turn on Sync.
3. Clear app cache: Settings > Apps > Gmail > Storage > Clear cache.

On iPhone

• Open Gmail app, pull down to refresh.
• Settings app > Mail > Accounts > Gmail > ensure Fetch or Push is enabled.
• Restart phone and update the app.

Domain or account problems

For custom domains or Google Workspace, MX records, suspensions, or expired registrations block all incoming mail. Personal accounts rarely hit this, but check if applicable.

Outages or verification emails from hosts can disable delivery.

• Check Google Workspace Status Dashboard for outages.
• Verify domain MX records point to Google's servers (via domain host panel).
• Log in to Google Admin console if Workspace user; check for suspensions.
• Confirm domain registration and payments are current.

When to call a professional

Seek IT support or Google Workspace admin help if basic fixes fail and you suspect server-side issues. Contact your domain host for MX/DNS problems.

• Account suspended or domain disabled per admin notices.
• Persistent outages shown on status dashboard.
• Custom domain with verified MX but still no delivery.
• Security alerts or repeated failed authentications.

Frequently asked questions

Why am I not receiving emails from one specific sender?

Check if they're blocked, filtered to Spam, or if your storage is full causing bounces. Ask them to resend and whitelist their address.

Does antivirus software block Gmail emails?

Yes, some scanners quarantine emails or interfere with IMAP/POP. Disable temporarily, scan your system, then whitelist Gmail.

What if I use Gmail with a custom domain?

Verify MX records are set to Google's (aspmx.l.google.com etc.). Check domain registration and Google Workspace status.

Why does Gmail say my mailbox is full but inbox looks empty?

Storage includes Drive/Photos. Search for large attachments and empty all folders to free space.

Can app updates fix Gmail sync problems?

Yes, outdated apps miss security patches. Update Gmail app and your device OS, then re-sync the account.

Is it a Gmail outage if only my account is affected?

No, outages affect everyone. Check status dashboard first, then your filters/storage for account-specific issues.
