You can make multiple emails on Gmail, and add the tag to all of them to speed up the process even further. The script checks for the link, runs the unsubscribe process if a link is found, and adds the information to the spreadsheet on Google Sheets (this may be delayed by a few minutes). Once you have done all that, you may unsubscribe from any mailing list or newsletter that uses the header field by tagging it with the unsubscribe tag. Please note that the script does not upload data to third-parties, it runs on the Google Account only, and only you have access to the data. You need to provide the script with permissions to access data of the Gmail account, and to change data on the Google Sheet spreadsheet. You see it highlighted in read on the screenshot above.

Once you have done that, click on the Gmail Unsubscriber menu entry on the Google Sheets site. The script parses the field, and if it finds an URL, opens it to unsubscribe you from the list. This field, used by all legitimate services, contains an URL or an email address that you may use to unsubscribe. How it works? It checks for a list-unsubscribe field in the message header. Once set up correctly, it enables you to send unsubscribe notices to select mailing list senders by tagging emails with the unsubscribe emails. The activity is stored in a log that is kept on Google Sheets. Gmail Unsubscribe is like that, but without involvement of a third-party. Users grant the service access to their mailboxes for that, as it would not work otherwise, and accept the terms of service which state that data may be sold in anonymized form.

is a service that provides you with options to unsubscribe from mailing lists. It was created by Amit Agarwal, the creator of Digital Inspiration, as a direct response to the incident.

Gmail Unsubscribe is an open source script that changes that.
