I have started getting daily LLM-written outreach emails. They all follow the same exact pattern, but come from different people pitching different vibe-coded things. The authors are real people with LinkedIn profiles, usually AI gurus, rarely experts in their niche. The message is usually targeted compliment pitch call to action. The compliment is the biggest tell because it s so neat and specific.My question: which tool are they all using? Why has it become so popular almost overnight? How do I reliably block those emails?
