What to Know About Blocking

• Blocking a sender doesn’t stop them from emailing you—it just redirects their messages to your Junk folder.
• It’s not a full-proof spam solution, but it works well for persistent, known addresses.
• Consider creating rules for more advanced email filtering (e.g., by subject or keywords).
