Visit Mailchimp EepURL We created EepURL as a trackable shortening service for Mailchimp's built-in Twitter integration. At the time; we opened it up to the public, because we felt there werent enough monkey-based URL shorteners out there_ This service is no longer available for public use We made this change in order to protect the reputation of the 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 you're looking to build your own url shortener; take moment t0 look at Shaun Inman's Lessn Building your own url shortener is good way to avoid having your links connected to blocklisted domain name
