If you wish to block the whole domain or filter emails containing specific words, Gmail spam filter setting would give you a hand.

  1. Get logged into your Gmail account.
  2. Click the down arrow icon in the search box at the top.
  3. Type the email that you would like to block. Note: To block the whole domain, you should enter “@example.com“ In the From text box. As for two or more email addresses, please separate each of them with a vertical bar “|”.

How to Block Someone on Gmail on Chrome and Firefox?

You can block annoying email addresses in Gmail with the help of Chrome extension and Firefox add-on- Block Sender, which exists in both two platforms. In Firefox, it named as Block Sender for Gmail some while.

Pros:

  1. Block emails from individuals, domains or same subjects
  2. Pause unblocking
  3. Undo accidental blocks
  4. Add auto response to blocked sender

Cons:

  1. Need create an account
  2. May get daily porn spam
  3. The free version doesn’t work as expected

Although Block Sender declares that it can block individuals, unwanted junk emails, newsletters, and uninvited email senders on Gmail, plenty of users leave negative reviews, saying it’s at least not as advertised. So, I recommend you to use the free version for a period of time and then decide whether to upgrade it or not.

  1. Add Block Sender to Chrome or Firefox.
  2. Sign up an account for the extension and log in.
  3. Open an email from a sender you need to block.
  4. You will see a Block button at the top. Click the button > choose an option to block someone, the entire domain or the same subject.

How to Block Emails on Gmail on Mobile Phone without Opening Them?

IOS and Android users now are able to block someone using Gmail app, too. You can download the app or log into Gmail via a browser. The steps have a strong resemblance to the desktop version. I won't say much more here. But in case of the Gmail app doesn’t work from a mobile device, what kinds of first aid or smarter measures you will take? For me, phone blocker is the best alternatives.

How to Block Someone on Gmail on iPhone?

Cisdem JunkMail Stop, a spam-stopping hero, takes a convenient approach to block someone on Gmail on the iPhone. It goes through your Gmail address and offers you a list of your new incoming mails, subscriptions, newsletters, and spams. Plus, it focuses on privacy and no data is sent to app’s servers. So, you can use it safely and confidently. Its key features are as follows:

  • Support adding multiple accounts and switching them freely
  • Block unwanted emails on Gmail from any contact and email address
  • Generate new folders for junk messages
  • Place the blocked emails in the specified folder
  • Turn on/off the block function in one press
  • Obtain spam list smartly

In the free version of the iPhone app, you can only add one Gmail account, and block three emails.

  1. Simply connect your Gmail account to the Mail Blocker.
  2. Search the email from someone that you determine to block. There are three search commands: user@example.com, user, or example.com.
  3. Active the block button (turn it on).
  4. Click the three-dots icon, and move the email sender to a specified folder(you won’t receive the emails from this person in Gmail inbox.)

How to Block Emails on Android Phone?

SpamDrain is designed to block legitimate emails, unwanted advertisements, virus and spam that sent to your Gmail inbox. It does an awesome job detecting spam, but the biggest downside is the price- $27.99/year (general version), $34.99/year (advanced version). Below are the main functions:

  • Get rid of junk mails before they get to your inbox

  1. Install the program on Android and sign up with Gmail account.
  2. Go to the inbox and swift to Allowed tab.
  3. Search the emails or scroll to the messages that you prepare to block.
  4. Tap the Newsletter/Marketing icon or the tick icon to the left of the message, and choose the type that you prefer blocking someone as Spam or Newsletter.

When releasing an allowed message, SpamDrain will analyze it and learn to block similar emails on Gmail in the future.

If I Block Someone on Gmail Will They Know?

Generally speaking, they won’t.

If someone who you have blocked on Gmail sends a mail to you, neither will they receive any failed-report nor successful or blocking related notices, unless you set an auto-reply for all blocked senders.

For those emails that failed to send, it’s just because of non-existent email address, full mailbox, unavailable or overloaded server and more.

But individuals can use email tracking tools like Gmelius, SalesHandy, Yesware, BananaTag, etc.to see whether their emails are being opened or not. If they send you a couple of emails and none of them are opened, senders will think that you have already blocked their email addresses in Gmail.

As a Gmail user, you may have the same doubt-“how to know that I am blocked on Gmail”. Sorry, the answer is, you won't know either.

Conclusion

The steps about “how to block someone on Gmail from sending you emails?” are not as simple as it looks. Gmail itself can filter useless, harmful emails or senders to spam, which will be automatically deleted after 30 days. But there are still many unwanted emails from someone sending to your inbox. We have to take further manual and more effective measures. No matter you're regular email user or a business owner, you shouldn't waste too much time coping with spam emails. And hope my post can help you improve it.
