+0.5 for Sendy. I've been using it for http://www.tittietime.com quite successfully for 2+ years now.

There have been a couple of bugs that caused me to have to dig into the source code - which as others have stated, is a mess. Though I suspect its been purposely obfuscated to prevent pirating.

If you ever wonder what's going on in functions.php, I've unwound it a bit - you can see its making a phone home:

Holy God in heaven that obfuscation filled me with dread.

I think he must have a deployment script that generates all the database connection calls at the top of every file when he releases a new version. No one in their right mind would write code like that.

They also leave a phpinfo() publicly available which I had to block
