Hi @John Tanner Worthington - So I don't have enough sending volume to be able to use clay yet so I'm manually checking if the leads I have qualify for my client's offer. Currently targeting PR agencies in the US, I've got over 3000 verified leads, but my worry is that not all of these are PR agencies as some are marketing and other unrelatable industries. I'm currently sending small batches of domains to chatGPT and prompting it to check the website homepage for PR related keywords, and then telling me if it's a PR agency or not. This is very time consuming though! What would you recommend doing instead and am I using the correct qualification prompt? any other things I need to prompt to make sure my offer resonates with the right audience?
