I'm sending out an e-mail containing a link as to prove the user had registered with an e-mail address they have access to.
1)What is the name of such an e-mail? Verification e-mail, confirmation e-mail, account activation or something else? In a similar sense what is the name of the link in the e-mail?
2)What should the e-mail say? I want to make this accessible to non-technically inclined users.
3)What should the subject of the e-mail be?
