I am a graphic designer who often builds HTML newsletters for some of
my clients.  Currently I am looking for a more robust solution to
fulfill my client's needs with a fully functional newsletter software
solution.  I am looking for the best software out there that will help
me streamline the creation and delivery of these HTML newsletters.

Please help me by gathering a list of the top software packages that
will help me build and send these Emails.  Note: I will be sending
some emails to more than 20,000 people.

For something like this, surely the value you put to knowing about
differnt solution is more than $5. Offer $20 and i'm sure you'd get a
thorough answer. ;)

The important question is what do you want to do beside compose an
HTML newsletter? What tracking needs do you have? How large is your
list that you are sending to? How do you want to handle bounced
emails? etc. Another important aspect is whether you will continue to
build the newsletter for your clients, or if this solution could
replace you! Keep that in mind before you share your solutions with
your clients. Please let email me if you'd like details.
