Email with proof of receipt (e.g. Outlook's read receipts) would be fine. But sending an email and hoping for the best doesn't meet that condition.
A read receipt is not proof of receipt but proof that you read it. They are not the same thing. If your office receives registered mail but your secretary threw it away without you reading it, you're still legally served right?
