How to Block Someone From Emailing You in Gmail (2026 Guide)

Getting emails from someone you never want to hear from again? Gmail makes it easy to block individual senders — but there are limitations most guides don't tell you about. Here's how blocking actually works, and how to go further when one-by-one blocking isn't enough.

How to block a sender on Gmail (desktop). Open any email from the sender you want to block. Click the three-dot menu in the top-right corner of the email (next to the reply button). Select "Block [sender name]." Confirm by clicking "Block" in the popup. Gmail will immediately move all future emails from that address to Spam. Done.

How to block a sender on Gmail (mobile). Open the Gmail app on iOS or Android. Open the email from the sender you want to block. Tap the three-dot menu icon in the top-right corner. Tap "Block [sender name]." Confirm the block. The process is identical whether you use an iPhone or Android — Gmail's mobile interface handles it the same way.

The important limitation: blocking only covers the exact address. If you block "promos@company.com", emails from "newsletter@company.com" or "offers@company.com" will still land in your inbox. The block applies to that one specific address, not the entire organization or domain. This is the most common frustration people run into after blocking.

How to block an entire domain. Gmail doesn't have a one-click "block all emails from this domain" button, but you can get the same effect with a filter. Click the search bar in Gmail. Type "from:@domain.com" (replace domain.com with the actual domain). Hit Enter to see the emails that would match. Click the search options dropdown (the slider icon on the right side of the search bar). Click "Create filter." Check "Delete it" (or "Mark as spam" if you want them recoverable). Click "Create filter" again to confirm. Now every email from any address at that domain goes straight to trash or spam automatically.

How to unblock a sender if you change your mind. Go to Gmail Settings (the gear icon) → "See all settings." Click the "Filters and Blocked Addresses" tab. Scroll to the "Blocked Addresses" section. Find the sender and click "Unblock" next to their name. They're unblocked immediately, though past emails that were sent to spam while blocked won't move back to your inbox.

What actually happens to blocked emails. Blocked emails don't disappear into a void. They go to your Spam folder, where Gmail holds them for 30 days before permanent deletion. This means if you accidentally block the wrong person, you have a month to check your Spam folder and recover their messages. The sender gets no notification that they've been blocked — their emails just silently go to spam.

Bulk-blocking many senders at once. If you're trying to block dozens or hundreds of senders — newsletters that never respect unsubscribe, repeat spam senders, promotional floods — doing it one address at a time takes hours. Gorganizer identifies every bulk sender in your inbox in 90 seconds and lets you block or remove them in one click. It also detects senders using rotating addresses (where the domain changes each time) that would slip past any manual block.
