Unwanted email can quickly fill an inbox and make important messages harder to find. Spam, repeated promotions, suspicious payment requests, fake delivery notices, and unwanted personal messages are common reasons people search for how to block emails. The correct method depends on the email provider and app you use, but most services offer a block, junk, spam, unsubscribe, or filtering option.

Blocking is only one part of inbox control. It is usually best for repeated messages from one known address. Reporting spam helps the provider identify unwanted campaigns, while unsubscribing is more suitable for a legitimate newsletter you previously joined. This guide explains the main options for Gmail, Outlook, Yahoo Mail, Apple Mail, iPhone, Android, and desktop users.
What Happens When You Block an Email Address?
Blocking usually changes where future messages appear rather than preventing the sender from pressing Send. Gmail moves future mail from a blocked address to Spam, while Outlook sends blocked mail to the Junk Email folder. Apple Mail can mark blocked messages or move them to Trash, depending on your settings.
The sender normally receives no special message telling them that you blocked the address. However, blocking one address may not stop a person or spammer who uses several accounts. A business may also send newsletters from different addresses. In these cases, reporting spam, creating a filter, or blocking a carefully selected domain may be more effective than blocking one sender at a time.
How to Block Emails on Gmail
To learn how to block emails in Gmail on a computer, open the unwanted message. Click the More menu beside the Reply button, then choose Block followed by the sender’s name. Gmail sends future messages from that address to Spam. To reverse the action, open a message from the sender, use the same menu, and select Unblock.
On the Gmail app for Android, iPhone, or iPad, open the message and tap the More menu beside Reply. Select Block and confirm the sender. Be careful not to use a different three-dot menu that controls the whole message screen. You can review blocked addresses on a computer under Settings, See all settings, and Filters and Blocked Addresses.
How to Block Emails on Outlook and Yahoo Mail
In new Outlook for Windows or Outlook on the web, open Settings, choose Mail, and select Junk email. Add the address under Blocked senders, or add a domain under Blocked domains, then save. In classic Outlook, right-click the message and choose Block, then Block Sender. Future mail from that address is moved to Junk Email.
In Yahoo Mail on a desktop browser, open Settings and go to Security and Privacy. Under Blocked addresses, select Add, enter the unwanted email address, and save it. You can return to the same area to remove an address later. Yahoo also offers a message-level Block Senders option in some versions, so the exact layout may differ.
How to Block Emails on Apple Mail and Android
On an iPhone, open the Mail app and select a message from the sender. Tap the sender’s email address, choose View Contact Card, and tap Block this Contact. On a Mac, Mail settings let you decide whether blocked messages stay in the inbox with a blocked label or move automatically to Trash.
Android does not have one universal email-blocking screen because people may use Gmail, Outlook, Yahoo Mail, Samsung Email, or another app. For the Gmail app, open the message, tap More beside Reply, and select Block. For another app, look for Block sender, Junk, Spam, or Rules. If the option is missing, use the provider’s website, where more controls are often available.
Blocking, Reporting Spam, and Unsubscribing
Use blocking when one recognizable sender keeps contacting you. Use Report spam or Report phishing for mass junk, fake invoices, account warnings, prize messages, or emails asking for passwords and banking details. Google specifically recommends reporting spam that reaches the inbox and reporting suspicious requests for personal information as phishing.
Use unsubscribe only for a sender you recognize, such as a store, news site, or service whose mailing list you previously joined. Business owners can also learn about responsible email marketing practices that focus on relevant messages, audience targeting and list management. Gmail may show an Unsubscribe option beside the sender’s name, and removal can take several days. Do not follow links inside suspicious messages. Visit the company’s official app or website directly when you need to manage genuine communication preferences.
Create Filters and Block Domains Carefully
A filter or rule is useful when unwanted messages come from many addresses or share the same words. You can create a rule based on the sender, subject, domain, or phrase, then move matching mail to Spam, Junk, Trash, Archive, or a separate folder. Test the rule with a narrow condition before applying it widely, especially on a work or business account.
Blocking a domain stops mail from every address using that domain. For example, blocking example.com could affect sales@example.com, support@example.com, and accounts@example.com. Outlook supports adding addresses and domains through its Junk email settings. Domain blocking is powerful, but it can hide legitimate invoices, customer messages, password resets, or job-related emails from the same organization.
Deal With Scam Emails and Repeated Spam
Phishing emails often create urgency. They may claim that your bank account is locked, a package cannot be delivered, or a payment is overdue. Do not reply, open unexpected attachments, download software, or enter private information after clicking an email link. Instead, open the real company website or app yourself and check the account there.
Blocked emails may continue when spammers rotate addresses, copy trusted display names, or send from new domains. Report each suspicious campaign as spam instead of only deleting it. Create a focused filter when the messages share a clear pattern, but avoid overly broad words such as “invoice” or “order,” because those rules could also capture genuine purchases and business messages.
Common Mistakes and Inbox Safety
Common mistakes include blocking a real contact by accident, clicking an unsubscribe link in an obvious scam, blocking an entire company domain, and creating rules that delete useful mail. Another mistake is assuming blocked messages disappear completely. Gmail sends them to Spam, and Outlook sends them to Junk, so check those folders when an expected message is missing.
Protect the account as well as the inbox. Use a unique password, enable two-step verification, review forwarding rules, and remove unfamiliar connected apps. Keep a separate email address for newsletters and online registrations when possible. Google recommends two-step verification as an extra layer of protection if a password is stolen.
Conclusion
Knowing how to block emails makes it easier to control repeated messages from individual senders. Gmail directs blocked mail to Spam, Outlook uses Junk Email, Yahoo provides a blocked-address list, and Apple Mail offers controls for marking or moving blocked messages. App menus can change, so check the provider’s current settings when a button looks different.
For better results, combine blocking with spam reporting, safe unsubscribing, and carefully designed filters. Report phishing instead of interacting with it, and avoid broad domain rules that could hide important mail. A few minutes spent reviewing blocked senders, Spam, Junk, and account-security settings can keep your inbox cleaner and safer.
FAQs
How do I permanently block unwanted emails?
Open a message, use the sender menu, and choose Block. The service may still receive the message but move it to Spam, Junk, or Trash. For changing spam addresses, also report the messages and create a careful filter.
Does a sender know when I block their email?
Email services normally do not send the person a special blocking notification. Their messages may appear to send normally, while your provider redirects them. A delivery error could still occur for another technical reason unrelated to blocking.
Why am I still receiving emails from a blocked sender?
The sender may be using another address, a different domain, or a mailing system with several accounts. Compare the full sender addresses, report the new messages as spam, and create a narrow filter when they share a reliable pattern.
Is it better to block or unsubscribe from emails?
Unsubscribe from a legitimate mailing list you recognize and no longer want. Block a specific person or address that repeatedly sends unwanted mail. Report suspicious, deceptive, or mass-produced messages as spam or phishing instead of clicking their links.
How can I block emails without opening them?
Some services allow you to select or right-click a message in the inbox and choose Block or Junk. When that option is unavailable, mark the message as spam without opening attachments or links, then add the address manually in settings.
Can I block all emails from one domain?
Some providers, including Outlook, allow domain blocking. Use it carefully because it stops every address from that domain. Blocking a company’s domain could hide support replies, receipts, security alerts, or messages from employees you actually need.
