ProtonMail also supports <a href="https://protonmail.com/support/knowledge-base/creating-aliases/">subaddressing</a>, which is useful for users who don't want to purchase a domain.</p>

    <h5><span class="badge badge-success">Payment Methods</span></h5>

ProtonMail is planning to implement U2F upon completion of their <a href="https://reddit.com/comments/cheoy6/comment/feh2lw0/">Single Sign On (SSO)</a> code.</p>

    <h5><span class="badge badge-success">Data Security</span></h5>

    <h5><span class="badge badge-success">Domains and Aliases</span></h5>
    <p>Mailbox.org lets users use their own domain and they support <a href="https://kb.mailbox.org/display/MBOKBEN/Using+catch-all+alias+with+own+domain">catch-all</a> addresses. Mailbox.org also supports <a href="https://kb.mailbox.org/display/BMBOKBEN/What+is+an+alias+and+how+do+I+use+it">subaddressing</a>, which is useful for users who don't want to purchase a domain.</p>

    <h5><span class="badge badge-warning">Payment Methods</span></h5>
    <p>Mailbox.org doesn't accept Bitcoin or any other cryptocurrencies as a result of their payment processor BitPay suspending operations in Germany. However, they do accept <strong>Cash by mail</strong>, <strong>cash payment to bank account</strong>, bank transfer, credit card, PayPal and couple of German-specific processors: paydirekt and Sofortüberweisung.</p>

    <h5><span class="badge badge-success">Account Security</span></h5>

    <h5><span class="badge badge-warning">Data Security</span></h5>
    <p>Mailbox.org allows for encryption of incoming mail using their <a href="https://kb.mailbox.org/display/MBOKBEN/The+Encrypted+Mailbox">encrypted mailbox</a>. New messages that you receive will then be immediately encrypted with your public key.</p>
    <p>However, <a href="https://en.wikipedia.org/wiki/Open-Xchange">Open-Exchange</a>, the software platform used by Mailbox.org, <a href="https://kb.mailbox.org/display/BMBOKBEN/Encryption+of+calendar+and+address+book">does not support</a> the encryption of your address book and calendar.

    <p>Mailbox.org has <a href="https://kb.mailbox.org/display/MBOKBEN/Send+encrypted+e-mails+with+Guard">integrated encryption</a> in their webmail, which simplifies sending messages to users with public OpenPGP keys. They also allow <a href="https://kb.mailbox.org/display/MBOKBEN/My+recipient+does+not+use+PGP">remote recipients to decrypt an email</a> on Mailbox.org's servers. This feature is useful when the remote recipient does not have OpenPGP and cannot decrypt a copy of the email in their own mailbox.</p>
    <p>Mailbox.org also supports the discovery of public keys via HTTP from their <a href="https://wiki.gnupg.org/WKD">Web Key Directory (WKD)</a>. This allows users outside of Mailbox.org to find the OpenPGP keys of Mailbox.org users easily, for cross-provider E2EE.</p>

    <p>You can access your Mailbox.org account via IMAP/SMTP using <a href="https://kb.mailbox.org/display/MBOKBEN/The+Tor+exit+node+of+mailbox.org">their .onion service</a>. However, their webmail interface cannot be accessed via their .onion service, and users may experience TLS certificate errors.</p>

    <h5><span class="badge badge-info">Extra Functionality</span></h5>
    <p>All accounts come with limited cloud storage that <a href="https://kb.mailbox.org/display/MBOKBEN/Encrypt+files+on+your+Drive">can be encrypted</a>. Mailbox.org also offers the alias <a href="https://kb.mailbox.org/display/MBOKBEN/Ensuring+E-Mails+are+Sent+Securely">@secure.mailbox.org</a>, which enforces the TLS encryption on the connection between mail servers, otherwise the message will not be sent at all.</p>
