I bought this to replace Mailchimp in a PHP application. The forms, the list management and the broadcast sending all work well, and I had a real campaign built and delivered to my inbox inside an hour. If you run a normal website and you want popups, landing pages and a newsletter you send by hand, this is a good deal and you will be happy.

So I mapped it myself. The good news is the key does authenticate against a real API and quite a lot works: reading sites, reading and creating lists, reading contacts, reading a broadcast with its stats, and replacing a broadcast's subject, sender and full HTML body.

The bad news is the single most important call is missing. There is no endpoint to add a contact. Every plausible route returns a 404. That is the one thing almost any integration needs. Your own Zapier app has a "Create New Contact" action, so the endpoint exists internally, it is just not available to me.

So this thing does have some potential and I'm not going to ask for a refund just yet. I wish them luck with their sales, but if the API can't add contacts, then this is totally useless for most of us. Perhaps it's work in progress. In which case I'd give this a solid 4 tacos after all.

WHO SHOULD BUY THIS

You run one or a few of your own sites, you want good looking forms and landing pages, and you will write and send your campaigns in the dashboard. Great value.

WHO SHOULD NOT

You need to push signups into it from your own code. You need to send campaigns on a schedule your application controls. You are building for multiple clients who must not share a contact list. Test all of that inside the refund window, because none of it is documented and you will not find out until you try.
