Use the block sender feature in Gmail
Gmail makes it simple to stop mail from specific addresses. You can block an email at the web interface or in the mobile app.
In Gmail web, open any message from the sender, click the three dots, and choose Block [sender]. On Android or iPhone, open the message, tap the sender name, and select Block this person.
Blocked senders go to the Spam folder, and future mail from them is automatically discarded. You can review and unblock addresses in Settings under See all settings and Blocked addresses.
Block email in Outlook.com and Outlook desktop
Outlook.com and the desktop app provide clear options to block unwanted email and manage your safe senders list.
In Outlook.com, open the message, choose Junk, and then Block sender. In the desktop app, right-click the message, point to Junk, and select Block sender. You can manage blocked accounts in Settings under Mail > Junk email > Blocked senders.
These actions prevent future mail from reaching your Inbox and move existing messages you select to Junk.
Block email on iPhone and Android mail apps
Mobile devices give you fast ways to block email at the device level when you do not have web access to your account settings.
On iPhone, open the message, tap the sender at the top, and choose Block this Caller. On Android, open the message, tap the sender or three dots, and select Block. Note that device blocking usually applies only to the built-in mail app and may not affect web access.
For cross-device protection, use your email provider’s web settings or admin controls.
Set up rules and filters to block email automatically
Rules and filters can automatically block email based on sender address, subject keywords, or other criteria.
In Gmail, create filters in Settings and choose Skip the Inbox and Delete it, or mark as spam. In Outlook, use Rules in Home > Rules to move, delete, or block senders matching specific conditions. On other platforms, look for Filters or Rules in Settings and define conditions that match unwanted mail.
Use precise addresses or domains to avoid blocking legitimate messages by mistake.

FAQ
Reader questions
Will blocking an email address stop newsletters and marketing mail?
Yes, blocking the sender’s address typically stops future mail from that address, but marketing platforms may use multiple sending domains. For better control, use the unsubscribe link first, then block the address if mail continues.
Can I block emails from a group or mailing list with one action?
Block the main list address, and, if needed, add individual senders to your blocked list. Be aware that replies from different members may still arrive, so check your mail provider’s support for blocking by domain or header rules.
What happens to existing emails from a blocked sender?
Blocking only affects future mail. Existing messages remain in your folders unless you move or delete them. Some providers move blocked mail to Spam or a separate folder you can review periodically.
Is it possible to block email across my whole organization from one place?
Yes, domain or gateway-level controls let administrators block email for all users. These settings, often found in admin console or security policies, apply consistent protection and reduce the need for individual changes.
