Gmail Not Receiving Emails? 10 Fixes That Work in 2025

Gmail is usually rock-solid, but when emails stop arriving it can feel like a black hole opened up in your inbox. The causes range from simple (full storage) to subtle (a misconfigured filter silently deleting messages). Here's how to diagnose and fix every scenario.

Fix 1: Check Your Google Storage Is Not Full

Gmail, Google Drive, and Google Photos all share the same 15 GB free storage pool. When this fills up, Gmail stops accepting new incoming emails — and senders receive a bounce message.

1. Go to one.google.com/storage
2. If your storage shows 100% used, you must free up space before email can arrive again
3. Delete large files from Google Drive, empty Google Photos trash, and delete old emails with large attachments
4. Alternatively, upgrade to Google One (from $2.99/month for 100 GB)

Fix 2: Check Your Spam and Other Folders

Gmail's spam filter is aggressive. Legitimate emails from new senders, newsletters, or emails with attachments often land in Spam.

1. Open Spam in the left sidebar (scroll down or click "More")
2. If you find a misclassified email, open it and click "Not spam" — Gmail will learn to deliver future messages correctly
3. Also check the Promotions, Social, and Updates tabs at the top of your inbox
4. Check All Mail — if the email appears there but not in Inbox, a filter has archived it

Fix 3: Check for Filters That Delete or Skip Inbox

A Gmail filter with "Delete it" or "Skip the Inbox" can silently intercept emails — even ones you're expecting. This is one of the most common and least obvious causes.

1. Open Gmail → click the Settings gear → See all settings
2. Go to the Filters and Blocked Addresses tab
3. Review every filter carefully — look for any that say "Delete it" or "Skip the Inbox (Archive it)"
4. Delete or edit any filter that shouldn't be there

Fix 4: Check If the Sender Is Blocked

If you blocked a sender by mistake, their emails vanish silently. You never see a notification — the messages go straight to Trash.

1. Go to Settings → See all settings → Filters and Blocked Addresses
2. Scroll to the Blocked Addresses section
3. If the sender's address appears, click Unblock

Fix 5: Check Email Forwarding Settings

If forwarding is enabled and the destination address is invalid or the forwarding rule has been tampered with, incoming emails may be rerouted and never appear in your inbox.

1. Go to Settings → See all settings → Forwarding and POP/IMAP
2. Under Forwarding, check that forwarding is either disabled or pointing to an address you control
3. If you see an unfamiliar address, remove it immediately — your account may be compromised

Fix 6: Verify the Sender's Email Is Correct

Ask the sender to double-check they are emailing the right address. Even one character difference (e.g., [email protected] vs [email protected]) means the email goes to a completely different account or bounces.

Fix 7: Check If Gmail Is Down

Google services occasionally experience outages. Check the official status page at workspace.google.com/status. If Gmail shows a disruption, wait for Google to resolve it — nothing on your end needs changing.

Fix 8: Re-sync Gmail on Mobile

If you're using the Gmail app on Android or iPhone and emails aren't appearing, the app may have lost sync.

1. Android: Pull down on the inbox to force a refresh. If that fails, go to Settings → Accounts → Google → your account → Sync now
2. iPhone: Go to Settings → Mail → Accounts → Gmail → toggle Mail off and back on
3. Alternatively, remove and re-add your Gmail account in the app

Fix 9: Check Vacation Responder / Auto-Reply Is Not Causing Issues

If your Vacation Responder is on but misconfigured, it won't block incoming mail — but it's worth checking for other settings while you're in Settings.

Go to Settings → General → Vacation responder and make sure it's off if you're not actually away.

Fix 10: Check Third-Party App Access

A connected app (e.g., an email client, CRM, or automation tool) with broken or excessive permissions can interfere with your inbox. Audit connected apps at myaccount.google.com → Security → Third-party apps with account access and revoke anything you don't recognise or no longer use.
