You can email Minecraft if you have any questions about Minecraft. That's what the Minecraft Help Email is.
He doesn't have a minecraft email.
No, you do not need to confirm your email to play Minecraft.
Send it in a message to whoever you want to send it to.
if you mean 'every games servers' then no you cannot. put type in cracked minecraft <insert vesion here> and you will find a couple of hundred servers. BTW if you want to play 4 player on minecraft 1.2.5 cracked (if you or a mate have a server) then email me and ill play aswell (yep, i am VERY bored) and if you have any other questions, email me (if you email me and your not the person i want to email me then haha, it dont have my personal details LOL) doggygowoof@live.co.uk
If you want a Minecraft code, you should ask on the official forums (minecraftforum.net) or enter one of the many competitions on there or on YouTube.
The email used for a migrated Minecraft account will be the same as the email used to sign up for the Minecraft account (unless you have specified otherwise). Go to Mojang's website to try recover your email if you cannot remember.

Sadly, you cant change your minecraft e-mail
If you're in the US then it is $26.95 It's a one time only cost and you will need an email and a name you want your person in minecraft to be called and a password to log into the game.
No you cannot change your minecraft email account, but it is possible to change your screen name by loging in to minecraft.net with a different computer...
I'm sorry, but you can't. You will need an email :(
