Many ESPs these days license 3rd party editors that cost them recurring fees on a per user basis. Unlike hosted solutions, like BigMailer.io or SendGrid (both license drag and drop Bee editor), Sendy charges a very low one-time (!) fee of $59 to download the software once.

Sendy's pricing model simply doesn't allow such 3rd party product licensing and I imagine maintaining a heavy front-end application like a drag-and-drop template builder across the variety of clients is too costly (dev and support time) as well.
