If your emails are disappearing from your Gmail inbox, you're not alone. It's a common issue with several possible causes — some technical, some user-related, and some due to how filters or settings work. The good news is that most of the time, these emails haven’t actually vanished forever. Here’s what might be going on.

1. Accidentally Marked as Read or Muted

One of the simplest explanations is that you're seeing the result of Gmail’s default behavior. If you hover over an email or preview it without opening, Gmail may automatically mark it as read depending on your settings. Once marked as read, it can blend in with other messages, making it seem like it disappeared.

Also, if you've muted a conversation, new replies won't show up in your main inbox — they go straight to the "All Mail" label instead.

What to do:

• Check your "All Mail" label — missing emails are often there.
• Look for a blue "Muted" tag next to conversations.
• Adjust your preview settings if you use the sidebar or split view.

2. Filtered or Forwarding Rules Are Kicking In

Gmail allows users to set up filters and forwarding rules, which can silently move, archive, delete, or forward emails without any obvious sign.

For example, a rule might send all emails from a specific sender straight to the trash or apply a label and skip the inbox.

How to check:

• Go to Settings → See all settings → Filters and Blocked Addresses tab.
• Review any active filters to see if they’re moving or deleting messages.
• If you’ve set up email forwarding, make sure you didn’t enable “Delete it” when creating the rule.

3. Emails Are Going to Spam or Promotions by Mistake

Gmail uses smart categorization to sort incoming mail into Primary, Social, Promotions, Updates, and Forums. If you're only checking the Primary tab, you might miss emails sitting in another category.

Also, sometimes legitimate emails get incorrectly flagged as spam.

Check this by:

• Looking under each tab at the top of your inbox.
• Visiting the Spam folder occasionally to see if anything got misfiled.
• Reporting false spam if needed.

4. Third-Party Apps or Plugins Are Messing Things Up

If you’ve connected third-party apps or browser extensions to Gmail (like productivity tools, unsubscribe services, or email cleaners), they could be automatically archiving or deleting messages.

Even calendar integrations or CRM tools sometimes interact with your inbox in unexpected ways.

To investigate:

• Go to your Google Account → Security → Third-party apps with account access.
• Revoke access from any unfamiliar or unused apps.
• Try disabling browser extensions one by one to see if the problem stops.

5. You’re Using Multiple Devices or Email Clients

Sometimes, actions taken on one device (like marking as read, archiving, or deleting) sync across all devices. But occasionally, sync issues happen — especially if you're using IMAP or POP clients like Outlook or Thunderbird.

A message might disappear from your phone because it was archived on your desktop, or vice versa.

Things to consider:

• Double-check across all devices and apps.
• Make sure your client settings match your expectations (e.g., what happens after sending or reading an email).
• If using IMAP, verify that folders are syncing correctly.

That’s about it. Most of the time, the culprit is a filter, a setting you forgot about, or a misplaced expectation about how Gmail handles messages. Start by checking the "All Mail" label and reviewing your filters — those two steps usually solve the mystery.
