2) Why do you need this?
3) Not nice immediately asking for something without posting an introduction or anything else.
4) Just try to contact an AV company and send them a mail that you can't license your software or whatever and grab the HTML template they're using as email.
Nobody is going to have an AV's mail template probably you'd be better off trying to se that instead of method 4.
For example:
Hidden Content
You must
[To see links please register here]
or
[To see links please register here]
to view this content.
Try something like that?
