In this concise instructional video, Jimmy Fung critiques five common cold‑email subject lines, assigning each a tier from D to S. He explains why each line fails or succeeds based on criteria such as personalization, specificity, relevance, honesty, and social proof. The D‑tier line is a generic “First name, I have an idea for company,” which he says is overused. The B‑tier lines include a personalized but vague “I have an idea for company” and an honest “Not sure if this is relevant, but—,” both of which suffer from lack of clarity or confidence. The C‑tier line (“Can I send you a quick video?”) is dismissed because strangers rarely want to watch a video. The A‑tier line (“Saw your recent post or interview”) works if it references something specific inside the email. The S‑tier line (“Got insane result for similar company”) provides concrete social proof of past success. He ends with a call‑to‑action, inviting viewers to comment for a follow‑up video on the best emails for AI services.
