Lists of ChatGPT prompts for marketing?

Hi! Recently I've been seeing a lot of ads for ChatGPT prompts for marketing. Stuff like "YOU NEED TO HAVE THESE 10 000 GENIUS PROMPTS TO SUPERCHARGE YOUR MARKETING". Of course they're all quite expensive and look a bit dodgy. Do you have any experience with such resources? Are they actually useful and well-built? If so, which ones would you recommend?
