EepURL We created EepURL as a trackable shortening service for Mailchimp's built-in Twitter integration At the time, we opened t0 the public; because we felt there weren't enough monkey-based URL shorteners out there; This service is no longer available for public use. We made this change in order t0 protect the reputation ofthe domain and high deliverability rates for Mailchimp customers who use EepURLs in their campaigns Existing URLS are still being redirected, and EepURL still works in the app: If youre looking t0 build your own url shortener; take a moment t0 look at Shaun Inman's Lessn Building your own url shortener is a good way t0 avoid having your links connected t0 a blocklisted domain name it up
