Gmail spam filters usually work fine, but that doesn’t mean they block absolutely everything. If we get any unwanted messages on Gmail and cannot find the option to unsubscribe from the list of subscribers, then we should create our own filter that will automatically delete the relevant messages or move them to the spam folder.
How to block emails and subscriptions
To do this on your computer, go to Gmail and open an email from the sender whose emails you subscribe to. Next to its name, click Cancel subscription or Change preferences. If you don’t see these options, you can block the sender or mark the email as spam.
Blocking email address
E-mails from the sender you blocked will be directed to the Spam folder. Open Gmail first, then open the message. In the upper right corner, click More and select Block user “[sender]”.
If you have blocked someone by mistake, you can also unblock them by following the same steps.
Create your own filter
To do this, expand the “More …” option and select “Filter messages of this type”. By default, the filter is set to take into account all messages received from the sender. However, if you want to set a more complex blocking (e.g. based on the subject of the message), you can modify the form. Delete the sender’s address and enter the subject of the message or keywords based on which you want to block messages.
To set what happens with messages that match your new filter, you’ll need to click “Create filter based on these search results” in the bottom right corner. Another window will be displayed in which you should choose from the list of available options what Gmail should do with messages matching the criteria previously provided.
If you want to completely delete messages that match your criteria, just select “Delete”.
If you see an email asking for personal information that you think is suspicious, you can report it as a phishing scam. Open Gmail and open suspicious e-mail. In the upper right corner, click More, and then click Report Phishing.
You can also make sure that you block unwanted attachments like a G Suite administrator.
With the G Suite administrator role, you can set up compliance rules for message attachments, such as documents, video files, images, etc. These rules determine the conditions based on the file type, file name, and message size. They also specify how to handle messages that meet these conditions.
If the email contains an attachment, you can discard the message, quarantine it and the attachment, or change the delivery of the message and attachment.
You can also configure a rule to detect encrypted attachments. This is extremely useful if you need to send unencrypted copies of message attachments to the archive server to meet specific legal requirements.
