Yes. The people communicating with you can continue to send encrypted emails with the services and addresses they are already using. As a result, we don’t confine our users to our own digital island.

In the case of OpenPGP, we provide our users full control over their OpenPGP key management via an integrated keystore.This allows you to do all your OpenPGP crypto-operations without any restrictions – in addition to exporting your data and keypair (or revoking it) or migrating at anytime.
