I've played around with ConvertKit and it seems like a much simpler and user friendly site than Mailchimp--which I've been using for 2 years for Landing pages, audience collecting, newsletters. However, I LOVE using Calendly for scheduling/payment. Is there any chance you will be directly integrating "emailing collecting into your audience" and other Calendly integrations? If you had this, I would be switching over from Mailchimp to ConvertKit today. Thanks for listening to my feedback.
