Tuta Mail like Encrypted Email Service

Hi, does The-Online.com offers encrypted email or secured email service like Tuta Mail (Tutanota). I basically need end-to-end encrypted email either free or paid service mostly in non-U.S. location like Germany in Europe or Switzerland. The mail service should have secure web client or iOS and Android app and desktop client and no ads (ad free). I need about 10GB of private email storage with privacy-friendly email and 2FA enabled account. A custom email domain for my business is also a needed feature if you offer it. Kindly recommend such Tuta Mail like email service.
