If you own domains, there are situations where you would certainly want to be alerted if an issue arises… for example if a domain registration renewal failed due to an old credit card number.

So it’s a great idea for a registrar like GoDaddy to offer a text message - in addition to the usual email - if something is expiring, for example.

Until the marketing assholes decide to force you to also accept marketing messages if you want important tech/admin messages.
