How to Block an Entire Domain From Contacting a Gmail Address

This short guide explains how to block an entire domain (example.com) from being able to send email to your Gmail address.

Gmail has made it pretty easy to block a single email address from being able to send you mail. Blocking entire domains is pretty easy too, there’s just an extra step or two – here’s what to do:

1. Head over to Gmail in a web browser rather than an email App.
2. Open an email from one of the addresses of the domain you wish to block and then click the More button (the one that looks like 3 dots on top of each other, found in the upper-right corner of the email message). Select Filter messages like this from the list of options.
3. In the From field change the address from username@domain.com to *@domain.com and then click the Create filter button.
4. Finally, select Delete it from the list of actions. If you want to delete all of the messages that have been previously sent to you from that domain, place a check in the Also apply filters to x matching conversations box. Click the Create filter button when you’re done.
5. That’s it! From now on whenever someone email you from an address using the domain in question, it will be deleted.
