Oh I’ve gotten weird about email, for sure — but this is more of an example of “the prototype goes to production”.
I put these filters in place long before iPhones were a thing, and when the only devices that supported push notifications were BlackBerry (maybe? I didn’t have one) and pagers.
In the early 2000s if I wanted to be notified to go home and check my email for something important, the email->sms gateway was really my only option.
