That's assuming your contacts check their email when they aren't expecting something. I do (and I also have delta chat!), but my parents, most older people who only use SMS or WhatsApp or whatever, and most younger people who get so much spam they just ignore email and only check it when they're expecting a verification code, all probably don't (the gmail audience, really).

Plus, it's painfully slow as a result of being email.
