You can bank ON it

I'd say "you can reach me at nutrax@nameofmydomain.com." But a quickie search seems to turn up the same AmE-BE thing--although there are a lot of uk or au or za addresses that want you to "email me at", as well as on.

Cool, thanks.

New Zealand:

It's much more common to hear "call me on" but, 'at' isn't anywhere near as rare as it used to me. Much like more people give the date as 'two thousand nine' rather than "two thousand and nine". But 'on rather than 'at' is still more common.

As for email addresses I always use 'at'. so you can email me at sneakerfish@....

I just checked my work's website and how it refers to contacting staff. It says She can be contacted on 644XXXXXXX or via email sneakerfish@....

Which is a nice little way of avoiding 'at' or 'on' by just saying 'via email' then going straight to the email address.

In German you are reached under a number.

(Off topic.) #13 reminds me of something. I may remember the details wrong, but when the BRD and the DDR were to vote on unification, there were posters in the East opposing it giving the number of the referendum, say 622, and then saying: "Keine Anschluss unter dieser Nummer."

"Keine Anschluss unter dieser Nummer" is what you hear when you dial a number that has been disconnected or doesn't exist. But of course Anschluss in that context also suggested the 1938 annexation of Austria. Pretty clever, I thought.
