Unblocking a sender does not automatically move their past emails out of Spam. Go to your Spam folder, open the message, and click Not spam .

You have two primary methods for unblocking senders on a computer: Open Gmail in your web browser .

Find a message from the blocked sender (often located in the folder) .

Check your Promotions , Social , or Updates tabs, as Google often sorts incoming mail away from the Primary inbox. To help resolve this quickly, let me know: Are you currently on a computer or a mobile device ?

This prevents accidental blocking or spam filtering in the future.
