Would it be beneficial to anyone if I create an open source alternative to Mailchimp? I never liked their pricing structure, and have relied on Sendgrid to send out newsletters for a few months. I dislike sendgrid's clunky UI which tends to lag, and not record user inputs often skipping some of your actions (like deleting lists).

I'm checking out existing projects out there, and trying out SendPortal right now. A lot of the existing free tools often lack basic services like Segmenting user lists. (shocker)

I'm thinking about making something simple and useful which would utilize AWS SES.

I could make something for myself in a jiffy. So I would love to know if others are interested too.
