Wow. This is a brilliant and fantastic new feature to [Gumroad](https://gumroad.com).
I use Gumroad to sell *[Delight is in the Details](https://shawnblanc.net/thedetails/)*, and I couldn’t be happier with the service. As a seller, Gumroad is extremely affordable and very easy to set up. And the user experience for the buyer is just as great — I wouldn’t be selling with them if I thought otherwise.
With their new email workflow stuff, you can set up scheduled emails and automated email campaigns that go out to your customers. It can be as simple as a thank-you email after someone has bought your product, or a whole series of communications.
I’ve been use [Zapier](https://zapier.com/) to connect Gumroad with [Mailchimp](http://mailchimp.com) to do something similar, but I’m paying $785/year for those two services. Gumroad now includes it for free. Though with Mailchimp I do get quite a bit more control of my email designs and flexibility as my email list grows with folks who are interested in my book but who haven’t yet bought it.
