I'm looking for ideas to manage dp's mailing lists for his website. Existing mailing list managers are quite expensive, so those options won't work. We need to send different emails to different groups- the idea is to send a certain email after being a member for one month, another one after 2 months, etc. kwim?
Any ideas? Or mailing list managers that aren't really expensive?
I'm toying with the idea of using text documents, and somehow organizing them in folders. But there has to be a better way that I'm just not thinking of.
