Mailfence

Mailfence strives to make the internet a safer place. That’s why we developed our encrypted email solution. But in our opinion, just offering secure and private email is not sufficient. Otherwise our users would need to use insecure solutions to manage their appointments, create and store their files or chat online. That is why Mailfence is much more than secure email. Mailfence allows you to organize your life through powerful productivity tools such as Mailfence Calendar, Mailfence Documents, Mailfence Contacts, Mailfence Groups, Mailfence Chat and Mailfence Polls.
