Block Sender for Gmail

Adds a Block button beside Report spam in Gmail, for selected emails and open emails.

Block Sender for Gmail puts a Block button in the Gmail toolbar, immediately to the right of Report spam. Use it when you select one or more emails in the list, or when you open an email. The button starts Gmail’s own Block action. Future mail from that sender goes to Spam. The first time you click Block, the extension explains that it reads the sender name, email address, and subject of the messages you chose, and it asks you to continue. Those details stay in the browser and are used only to block the sender. They are not sent to the developer. You can remove a block in Gmail under Settings, then See all settings, then Filters and Blocked Addresses.
