You don't need to drop email at all. If you trade protocol openness for encryption, you are acquiring technical debt. How long are going to do this dance of switching between instant messenger protocols? ICQ -> AIM -> MS Messenger -> Hangouts -> WhatsApp -> Signal -> ???.
Open protocols (open in specs and federated in access) are the only way to stop this madness.
