Protonmail
Protonmail is a privacy focused email client based in Switzerland which has partnered with non Swiss content delivery networks like Radware. ProtonMail offers cloud email, calendar, VPN, and cloud storage services. Protonmail has a marketing focus on privacy over competitors like Google or Microsoft.
Protonmail does currently have malicious user practices. For example when your subscription is up for renewal an invoice will be put on your account for the full renewal amount. If you picked a 12 month plan an invoice will automatically be placed for another 12 months. User support has told me there is no way to remove this invoice without paying, and my account will be disabled if not paid. Their conflict between their marketing of user rights vs predatory sales is very concerning.
