Define an ideal customer profile precise enough to build a lead list from, including buying triggers and disqualifiers. Use whenever the user mentions ICP, ideal customer profile, target market, buyer persona, target accounts, account list, who to sell to, market segmentation, or says their outbound isn't working and they aren't sure who to target. Also use before any lead sourcing or cold email work, because a list built from a vague ICP wastes every downstream step.
