We still have eMail in place. If they don't want to spend money on an SMS they can send an eMail.

If browser notification permissions would have a TTL, I'd might considering it. But until this happens I won't allow anyone to send me browser notifications. And even then I'd be very picky.

Emails have essentially become notifications anyway. All my emails are things like "your booking has been confirmed", "your package has been shipped", "your invoice is ready for download", "a login from a new device happened", "your flight is delayed", etc.

Emails have a mature ecosystem. We've been getting spam and scam emails since 1994, we have tools for dealing with it.
