E-mail Marketing

Hey guys, I'm curious, has anyone found any free online template builders for e-mail marketing? I want to keep my clients up to date with what we have going on, but I haven't been able to find a user friendly template builder that creates professional looking e-mails that I'm proud to send out. It's very important to me to be able to include photos in my updates.

When you do, please share. I just did emails to all mine, under a "Planning ahead...." with a personal note.

It definitely was worth the time, but I usually don't have little ones in the house anymore & can lick insomnia this way. I can see a auto thingy would be great.
