I have a question...

What makes a good score?

We look at various details of a mailing list, such as email frequency, how many people choose to unsubscribe from it using Leave Me Alone, how easy it is to unsubscribe from, and various other statistics. It is then measured up against all others and given a percentile rank between F and A+.

What browsers do you support?

The Subscription Score extension currently works with Chrome and Firefox. If we get requests for other browsers then we will create extensions them in future.

Where does your data come from?

Our scores are generated from usage data from our other project Leave Me Alone, which allows users to easily unsubscribe from subscription emails.

Will you add a new feature for me?

Maybe! We'll try and keep Subscription Score as lean and simple as possible, but if you have a good feature in mind then let us know!
