How to Block an Email Address in Google
Many email clients offer a way to block an email address directly so you won't receive any incoming email for it, but Google's Gmail takes a different approach. Rather than containing an email-blocking system, Gmail contains a robust filtering system. You can create filters to send email from specific email addresses directly to the trash, effectively blocking the email address from contacting you. Gmail will permanently delete each blocked email from your trash after 30 days.
Click the "Create a Filter" link to the right of the search box at the top of the Gmail page.
Type the email address you want to block into the "From" box in the format of "email@example.com."
Click the "Next Step" button.
Click the "Delete It" checkbox.
Click "Create Filter."
Tips & Warnings
- You can block multiple email addresses with a single filter by separating them with an "OR" in the "From" box. For example, you can block "firstname.lastname@example.org" and "email@example.com' by typing "firstname.lastname@example.org OR email@example.com."
- If you want to unblock an email address, you have to delete the filter. You can manage the filters associated with your email account by clicking the "Settings" link at the top-right corner of the Gmail page and clicking the "Filters" tab at the top of the settings page.
