If you’ve been thinking about using Constant Contact, you may want to take advantage of their special offer. Through Feb. 28, 2011 Constant Contact giving new users a free email template based on your existing site design. It’s a $99 value (and, actually, usually costs more than that through an outside designer).
The company does offer a 60-trial (up to 100 subscribers) as well.
And, yes, I use Constant Contact for my mailings.
