EXCEL ** Sent e-mail after cell changes ( Excel macro )

Hello,

I am looking for a solution on excel where when coloumn e is changed then email me with a coloumn plus the new e coloumn.

Thank you for interest and time

If make it clear sample is like this;

a1=product number
e1=user

if I change the user ( or manually type sth) there on e1 then it emails me with new user name and the number on a1
