Why LetterBar?
There were really two reasons that we decided to develop LetterBar. The first reason was that we always wondered what happened with our email address when we signed up for a newsletter at an e-commerce site. Did it get sold to 'related parties'? Did it get sold to spammers? Without a watchdog organization, we felt that the only way to figure out who the spammers were was to create an open system where anyone could see what happened after the signup.
Second, we wanted to surface the offers and pitches that websites make to their newsletter subscribers. Merchants will often pre-announce sales, offer deals or coupons to their email subscribers. We wanted to know whether it was worth signing up for a newsletter and felt the best indicator of future offers was prior offers.
So, explore the newsletters in our system. We are always looking to add new newsletters. Please feel free to add your favorite ones.
