Gmail Spam Blocker

Becoming frustrated every time you open your Gmail inbox?

Are you getting inundated with spam, unwanted newsletters, and the overenthusiastic chain letter? While Google does offer a rudimentary system for setting up filters to help sort out your mail, the process is extremely complicated and time-consuming. Luckily there is a Chrome extension that can take care of all your problems - with Gmail that is! Block Sender for Gmail will get rid of spam with just a few clicks of your mouse.

Installing Block Sender for Gmail is fast and easy. When you're ready to say goodbye to spam for good, visit the homepage at with your Chrome browser and click "Install Block Sender" to get started.

Next, Chrome will notify that it requires access your data on Google as well as your tabs and browsing activity. The application needs these permissions in order to be able to see when Gmail is activated and to add the new functionality for you. Click “Add” and you are ready to go.

Open up Gmail and look for an email that you wish to block and open it. At the top of the screen you'll now see next to the trash icon a new button called "Block". If you've accidentally blocked an address, you can find the undo option by clicking “Undo” in the yellow notification bar at the top of your screen.

Getting tough in individual spammers is great. However, sometimes blocking a single email address isn't quite enough. It is common practice for unscrupulous companies to send main from multiple different accounts on the same domain. Thankfully, Block Sender for Gmail can take care of this too.

Click the downwards arrow next to the "Block" button and you'll find a vast array of additional options.

- Clicking on the first option, "All email from this sender", is equivalent to clicking the Block button. “All email from this domain” will remove any email sent from the same domain, which makes it perfect for blocking emails from social networks and websites who tend to use different email addresses for different tasks. If its an email conversation thread that is bothering you, you can choose "All email with same subject" and it will instantly be sent to your trash with the rest of your blocked spam. The last option is "All email with a word/phrase", which will allow you to choose exactly what you want to keep out.

- One unique and clever aspect of Block Sender for Gmail is the “Respond with an error” email which automatically fills out a plausible error message which can be sent to the recipient, letting them know that their mail isn't getting through.

- Clicking “Options” on the drop down block menu will open up a new screen called Settings. This page will allow you to define the default action for when you click the Block button, decide whether blocked emails go to the trash or are archived, and how long the undo option remains after blocking. For power users, there are also advanced power options that you can unlock by upgrading to the premium version of Block Sender.

If you haven't already, make sure to visit and look at the benefits you get with the premium version (and imagine how much time, money, and stress you'll save!)

That's it - it really is that easy to block unwanted emails in Gmail. With just a simple click (or two) you know have a powerful flexible tool to bring you the clean inbox you've always wanted.
