Create filters in Gmail
Sometimes setting an email to your spam folder doesn’t do the trick. Sometimes, you need to create filters to make sure unwanted messages don’t clog your inbox.
You can do this in Gmail. Open the settings menu by clicking the gears icon, then head to the “filters” option up the top. There, click “create a new filter”, and you’ll see a number of options.
You can organise your filters by sender, subject, along with deciding which content within messages should be blocked.
