Admin's note : Name being important in the message -for the addressee to know whom it is about- its transliteration in cyrillic is allowed. (04/28/francky)
To sound more natural in Russian I'd rather said "Г-н Сергей Миненко дал мне ваш/твой email", which is in English "Mr. Sergey Minenko gave me your email adress".
I haven't really heard someone using "Ñлектронный адреÑ", though it's correct
