The reason this won’t get fixed is HubSpot knows it’s not a big enough issue for customers to leave HubSpot over. It’s a business decision. Although, I think a short-sighted one.
Pardot is really going after HubSpot customers, offering attractive pricing and we’re doing an analysis of moving over. Pardot does offer the functionality of deleting test submissions - at least that’s my understanding. If HubSpot does not address this issue it will make it harder for me to stick with HubSpot when we do a competitive analysis. Combined with the continued difficulties of syncing with Salesforce, the bot email activity HubSpot can’t filter out, their rudimentary scoring and limited web design tools, HubSpot keeps falling further and further behind their competitors.
