Email Architect alternatives

We've been using reply.io for two years now. It recently dubs as Zoominfo competitor. I like that move.

I don't know how Dragapp got such high reviews, but if they used to be good then they've completely gone downhill. Before I was a paying subscriber, their founder Duda was very quick to answer my questions. But once I actually became a paying subscriber of their annual subscription, all of a sudden Duda became unresponsive. They seem to lack a dedicated support team as well, as whenever I did get any kind of response, it was always from Duda and it's always with an aloof or begrudging attitude. Finally after two months of tinkering with their glitchy system and futile automations and nothing to show for it, I had enough of the non-sense and emailed Duda for a refund on my annual subscription--per usual, I got crickets. I even tried going to my account settings to cancel my subscription and, waddya know, you have to email them to cancel your subscription too! Great, let me just email them to beg them to cancel my subscription and have them ignore my emails again. How has this scam of a business not gotten into legal troubles yet?
