I'm trying to set up a paid newsletter featuring more in-depth content for my blog's subscribers (assets, source code, tutorials, etc.) and wondering what third-party services to use.<p>I currently use Mailgun for transactional emails and love it, but I'm not sure how to configure it with recurring subscription payments.<p>Mailchimp would require switching horses, but is designed more to work with newsletters and has a few plugins specifically for paid content.<p>Does anyone have experience with either service or paid newsletters in general? Has anyone configured a setup that uses both? Is that even a possibility?
