Subject lines

Body A — gap-led

Hi [Founder], [specific, concrete observation]. We're [Studio], a creative studio. We make AI-native UGC ads — dozens of on-brand, creator-style variations in days, at a fraction of a shoot — so you can test more angles without booking talent each time. Easiest way to see if it fits: let me mock up 2–3 for [Brand], free — you judge the quality, no obligation. Or 15 minutes if you'd rather talk it through. [Name] · [Studio] · [link]

Body B — proof-first, shorter

Hi [Founder], We made a couple of AI-UGC ad concepts for [Brand] on spec — no pitch, just easier to show than tell. [One-line reason/gap.] We're [Studio] — AI-native UGC + content, dozens of on-brand variations in days. Can I send them over? If they're useful we can talk; if not, they're yours.

Which to use

Gap-led when we haven't made anything yet and need to earn the right to. Proof-first when a spec demo already exists — always the stronger opener when it's available.
