The fastest way to stop unwanted emails

The simplest method depends on which email service you use. Gmail, Outlook, and Yahoo all have a block feature built into each message — you do not need to change settings or create filters. Open the email from the person you want to block, click the three-dot menu icon (or "More" button), and select "Block" or "Block this sender". The sender's future emails go straight to spam, and you will not see a notification when they arrive.

If you use a different email provider, the process is similar but the button location changes. Look for a menu icon on the email itself, or check your email provider's help section for "block sender" — the feature exists on nearly all services, though it may be called "block", "blacklist", or "add to blocked list".

Blocking is permanent until you undo it. The person does not receive a notification that you blocked them, and their emails straightforward fail to reach your inbox. They may not realize the block happened.

Key Takeaways

  • Gmail, Outlook, and Yahoo let you block a sender directly from the email by clicking the menu icon and selecting "Block".
  • Blocked emails go to your spam folder automatically, and you will not receive notifications when they arrive.
  • The sender does not know they are blocked and will not receive a bounce-back message.
  • You can unblock someone later by finding them in your blocked senders list and removing them.
  • If blocking does not work, you may need to report the email as spam or contact your email provider if the sender is using multiple addresses.

Where to find the block button in Gmail

Open the email from the person you want to block. In the top right corner, you will see three vertical dots. Click them, then select "Block [sender's name]" from the menu. Gmail will ask you to confirm — click "Block" again. From that moment on, all emails from that address go to spam.

If you want to unblock them later, go to Gmail Settings (the gear icon in the top right), click "See all settings", then go to the "Filters and Blocked Addresses" tab. Scroll down to "Blocked addresses" and click "Unblock" next to the name you want to remove from the list.

How to block in Outlook and Outlook.com

Open the email you want to block. Click the three-dot menu icon at the top of the message. Select "Block" or "Junk" depending on your Outlook version, then confirm. The sender's future emails will go to your Junk folder.

To unblock someone in Outlook, go to Settings (the gear icon), then "View all Outlook settings". Click "Mail", then "Junk email". Scroll to "Blocked senders" and you will see a list of everyone you have blocked. Click the X next to a name to remove them from the blocked list.

Blocking senders in Yahoo Mail

Open the email from the sender you want to block. Click the three-dot menu icon at the top right of the message. Select "Block sender". Yahoo will move that email to spam and block all future messages from that address.

To see your blocked senders or unblock someone, click the gear icon in the top right, select "Settings", then go to "Security and privacy". Under "Blocked addresses", you will see everyone you have blocked. Click the X next to a name to unblock them.

What to do if the person uses multiple email addresses

Some senders create new email addresses to get around a block. If you notice emails coming from different addresses but the same person, block each new address as it arrives. Most email services will eventually flag repeated attempts from different addresses as spam or suspicious activity.

If the unwanted emails continue despite blocking multiple addresses, mark them as spam or report them as abuse. This trains your email provider's spam filter to catch similar messages automatically. You can also create a filter rule that catches emails with certain keywords in the subject line or body, though blocking is usually faster for a single person.

Using filters and rules as an alternative to blocking

If you want to keep seeing the emails but have them skip your inbox, you can create a filter instead of blocking. In Gmail, open an email from the sender, click the three dots, and select "Filter messages like this". You can then choose to skip the inbox, mark as read, or move to a specific folder. The email arrives, but you do not see it unless you look in that folder.

Filters are useful when you want a record of the emails but do not want them cluttering your main inbox. Blocking is better when you do not want to see them at all. You can use both — block the main address and create a filter for any backup addresses they might use.

Reporting spam and abuse

If the emails are harassing, threatening, or clearly spam, mark them as spam or report them as abuse in addition to blocking. In Gmail, click the three dots and select "Report spam" or "Report phishing". In Outlook, click "Junk" then "Phishing" if it looks like a scam. In Yahoo, click the three dots and select "Report as spam".

Reporting trains your email provider to catch similar messages from other senders. It also creates a record if you need to involve law enforcement or your email provider's abuse team later. Blocking stops the emails from reaching you; reporting helps stop them from reaching others.

Frequently Asked Questions

Will the person know I blocked them?

No. They will not receive a notification, and their emails will not bounce back to them. They may eventually notice that you never reply, but they will not get a message saying you blocked them.

Can I block someone and still see their emails if I want to?

Yes. You can unblock them at any time by going to your blocked senders list and removing their address. You can also create a filter instead of blocking — this keeps their emails out of your inbox but stores them in a folder you can check later.

What if someone is harassing me through email?

Block them first, then report the emails as abuse or phishing. Save copies of the messages in case you need them later. If the harassment continues from new addresses or escalates, contact your email provider's abuse team or local law enforcement.

Does blocking work if someone uses a fake name or spoofed email address?

Blocking works on the email address itself, not the person's real identity. If someone is spoofing addresses or using many different accounts, blocking individual addresses becomes tedious. Report these emails as spam or phishing instead — your provider's filters will catch similar messages automatically.

Can I block an entire domain, like all emails from a company?

Most email services do not have a built-in domain block, but you can create a filter that catches all emails from a domain. In Gmail, go to Settings, click "Filters and Blocked Addresses", then "Create a new filter". Enter the domain (for example, @unwantedcompany.com) in the "From" field, and choose to delete or skip the inbox. This catches all emails from that domain without blocking individual addresses.
