Most often, Incorrect filters or email forwarding settings can prevent Gmail from receiving emails in your inbox. So I will suggest you to check following things.
- Check Filters: Let’s Go to Gmail Settings (gear icon in the top-right corner) → See all settings → Filters and Blocked Addresses. Here, you need to review all filters. If a filter is archiving, deleting, or skipping emails. You need to edit or delete it.
- Disable Forwarding: sometimes, Google users can’t get new emails because of the forwarding settings. So if it is enabled on your account, you need to go ahead and disable it. To do that, you need to follow the instructions given below. In the Settings menu, navigate to Forwarding and POP/IMAP. Check if emails are being forwarded to another address. Disable forwarding if it’s not required.
Save any changes and test by sending an email. This ensures your emails land in your inbox instead of being redirected or skipped.
