About

Cock.li is a professional free email service and XMPP address provider available both on clearnet and .onion domain. Since its launch in 2013, it has successfully provided stable email services to an ever-growing number of users. You need to register on their dark web site to be able to enjoy the facilities. To date, it has garnered a huge donation through BTC funding that helps it to offer the best services to its users. 

The email and XMPP service provider does not parse your email to bombard you with targeted ads. It also never reads your email contents unless directed by a legal court order. The site recommends you to encrypt your emails using PGP through a mail client add-on such as Enigmail.
