Hi Jacque!
This is a great question, and one that I am very happy to answer! I have been a very vocal spokesperson for Emma for about 4 years! To see what Emma is all about, check out their website:
http://www.myemma.comIt's hard to explain exactly why they are worth an upfront investment of $250, plus an annual monthly fee of $30, BUT I promise you that they are absolutely, hands-down the single best html email platform on the market.
I have tested Constant Contact, Reach Mail, Intelli-something, and several others. Emma's tracking technology is simply the best available. They keep the features really simple, and just build a rockin' product.
I would highly recommend giving them a call & taking the test drive. Oh yeah -- and Marathon Press actually became a reseller for Emma, and is offering a better price if you are looking for a small quantity of emails per month.
Now...as far as the email design goes, here is ours:
