If it is just a message on the screen you can un-tick the box in the Work Environment that asks to check for updates.
But as for e-mails I have not come across this before.
Maybe it is a teamwork thing? - I don't use teamwork.
Or you Archicad retailer is being kind enough to notify you - but I would have thought they would send just one e-mail if any at all.
Can you trace who has sent the e-mail and ask them not to?
Maybe an unsubscribe link in the e-mail?
Or of course you could upgrade.
