Well, in one way: yes - you can obviously receive data from third-part services by email, right in your KRYPT7
inbox.
But as `KRYPT7 is by nature end-to-end encrypted, you can only send encrypted data who can't be decrypted by those third parts. So for now, because the world outside is mostly in clear and because we are opposed to the idea that anyone but you and your direct recipients can read your data, you can't automatically inject data into third-part services.
