Hmm is there really a benefit of using SMS rather than email? Nowadays everyone just gets email notifications on their phone anyways right? Depending on the provider, you might not receive the notification as instantaneous as with SMS, but it should still arrive quickly. And emails are cheaper (or even free) to send than SMS.

Not everyone does. It's a typical 80/20 problem (the 80% being those who use the technology that's easy to develop for, the other 20% being the hard part). 80/20 not being the exact numbers, obviously.

That being said, you certainly don't _have_ to cover more than one way of sending notifications, but that's a decision to be made and the consequences acknowledged.
