Hey B2B marketers, how are you ditching just MQLs for sales-driving Product-Qualified Leads (PQLs)?

Most B2B marketers have realized amassing emails (and slapping MQL tags on them) isn't impacting sales. Worst off, all it does is waste your sales team's time reaching out to unqualified 'leads.' I'm curious: How are you ditching the MQLs' hamster wheel? And in its place, what are you doing to acquire prospects with declared buying intent for your product and sales team?
