A lot of techs have various programs will email automatically for various reasons. Some of these emails are important enough to want immediate notification.
Since we have email with A&A and the SMS we use is with A&A, it seems a bit odd to create a third party server to try to join the two up.
If it is possible to nominate an A&A hosted domain and email address to be passed via SMS (with the appropriate charges) -
Perhaps with an option to have complicated autogenerated email addresses for services that don't support PGP management and a tick box that absolves A&A from responsibility should the email address be spammed or abused.
