+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:
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.
I guess I can understand why I'm being downvoted, but I'll share more info.
FYI, the homepage is SFW.
This was a goofy idea that I launched 2 years ago to test out Amazon SES and Sendy along with some content marketing skills I was wanting to put to use.
At the moment I spend ~10 minutes each morning making the email. When I do a shirt, I wind up spending ~ 20 hours sending out ones I've sold.
It's got ~10k subscribers who are all loyal fans (60% open rate on emails). I'm selling about 100 shirts everytime I post one for sale. I think there's tons of opportunity that I am not realizing as I've lost interest.
I'd also be happy to work with someone else on this. I'm a software engineer that would love to have a project to hack on that had revenue.
I have tons of ideas on how to monetize this, but am not really interested in being the face of it.
Someone to organize a street team that could engage 18-34's via wet tshirt bar meet ups or the like would be great. Or a writing partner as I've seen lots of growth when regular content is being generated.

I've had zero problems with Sendy and SES on my platform over the past 2 years.
