It would depend upon whether you already have some presence on the web around your niche.
While I'll agree on the part about cheesy long-page-sales letters that most of them have with all sort of false scarcity, 10s of upsells and "ending tonight" urgency, but there are some nice folks too from whom you can get ideas and adjust to your requirement. For me what has worked the most is "money-is-in-the-list" idiom of IM gurus (- in simple terms email marketing.)
Here are some points I would suggest you to consider
- Try to start with a blog around your
topic.
- Create a series of email
autoresponders and offer some of the
best tips for free in return for a
double-opted in email address. (You
can check my profile page for the
autoresponder that I prefer.) Getting traffic will be one of the hard tasks, if you don't
already have a presence around your
niche. If you're in the same boat,

- Try to find out website/blog
owners who already have presence in
a similar niche as yours. Try
to leverage their subscriber base and
get their members opted in to your
list created above. You may ask, why
these site owners will open their
subscriber base for me? Well, if you
have a really solid product and you
can offer them some high share for
every copy sold through their link,
they may consider your offer.
- Make a relationship with your
list. This is BIG. The more genuine,
personal touch you can give to a list
more likely they will purchase products
from you.
- Think about your launch as a long term strategy. Today's ebook launch may help you with tomorrow's online training launch. Treat your prospects and customers well and they will take care of you.
I can go on... my clock is showing 3:00 AM. I would be interested in what others have to think.
All the best!
