Hi Deyson,
We do have plans to offer a paid version of Leadin in the future but we do not plan on removing the free version of Leadin, instead we would like to offer additional functionality for power users of Leadin that would provide even more value.
Regarding Sendy, you’re actually one of the first people to suggest a Sendy integration for Leadin, at the moment a Sendy integration isn’t on the roadmap for Leadin but that doesn’t mean it never will be. The way our team works is that we ravenously listen to our users feedback, and when a feature request is asked for enough and it makes sense in the grand product vision, we usually bake it into the plugin.
At the moment Leadin integrates with MailChimp, Campaign Monitor, Constant Contact, GetResponse and AWeber, but it’s likely we’ll expand this in the future.
I’ll definitely keep you posted as we have news on capturing submissions with EDD.
Thanks!
