How to Block Emails on Gmail

Gmail does a good job of sorting your incoming mail and placing it in the right places, including moving spam messages to the Spam folder. Still, some unwanted emails can get through and clutter your Inbox.

Blocking a sender is likely the simplest method to halt unwanted emails, directing future messages from that address directly to Gmail's Spam folder. We have a quick video tutorial that shows how to block unwanted emails so that you won’t see them in your Gmail inbox:

Unsubscribing vs. Blocking

Blocking emails and unsubscribing from them serve different purposes in managing your inbox. Blocking stops emails from a specific sender by sending them to your Spam or Trash folder. However, if you're dealing with subscription emails and wish to stop them, remember that blocking doesn't remove your address from the sender's mailing list, and won't prevent the sender from continuing to send messages

On the other hand, unsubscribing is a more proactive approach for emails you've signed up for, like newsletters or marketing emails. These emails typically include an unsubscribe link, often found at the bottom. By following this link and completing the required steps, you can stop receiving future communications from that sender.

For cases involving subscriptions, Clean Email provides its Unsubscriber feature, a convenient tool that identifies subscription-based emails. This allows you to easily unsubscribe from emails from multiple senders in one place, saving time and effort, particularly when dealing with a large volume of subscription emails.

Simply hit the Unsubscribe button, and the app takes over, following the unsubscribe links and completing the necessary forms or other actions on your behalf. This makes the unsubscribing process straightforward and efficient.
