@sun It was good because I could tell my dad to just reply to this chat message with your email message and I'll see it right away without losing it in a sea of other messages.

And then as the next step I could install it on his phone and enter his existing email credentials, and he could see my messages to the family in a better way, and still interact with the others who weren't onboard yet.

Now that onramp is gone, and it's just another WhatsApp.
