#Spam

Stop a sender's emails in Gmail: open a message, hit the three-dot menu, and Block. Here's how, how to unblock, and how to block a whole domain.

Block calls and texts on Android from the Phone app and Messages, manage your blocked-numbers list, silence unknown callers, and unblock anyone later.

Block and report spam texts to 7726, switch on your phone's caller ID and spam filter, use your carrier's free tool, and register with Do Not Call.
