What is the best way to create a database for an online newsletter and
how do I then pull the information from the database in order to send
it to these people in an email format?

It would depend on who is hosting your website/database. This will
pretty much determine how you are going to go about this process.

If you do not have a website/database, then its simply a matter of
choosing a host provider. this will be most likely determined by what
type of services you will require.

In my case, I develop in Coldfusion and use SQL for my database backend.

Hi, dkolin!

The best way is to sign-up with an online auto-responder, such as
Simpler Leads (http://www.simplerleads.com/affiliates/idevaffiliate.php?id=623881),
who can help you manage a newsletter database.
