can add email functionality too

[aviiciii]

i agree that sms can provide instant notification but so does email. also emails are free and can be easier to set up rather than setting up a twilio account

Seems reasonable. When I was developing this, I thought that maybe people do not check emails quite often but text message on their phone, they do.
But adding a choice between an email and text message can be done.

Do you want to take it up, and raise a PR?
