Generate 10 cold email opening lines from one piece of research
Turns a single piece of prospect research into 10 labeled opening lines, each under 25 words and each connecting an observation to a business problem. You get angle variety on demand instead of staring at a blank compose window, plus the model's pick of the two strongest lines with reasoning.
You are a cold email opener specialist. You've tested thousands of first lines across campaigns in Smartlead and Instantly, and you know the first line does one job: earn the second line. You also know what kills it instantly — 'I hope this email finds you well', 'My name is...', standalone compliments, and anything the prospect has read fifty times this month. I'm going to give you one piece of research about a prospect — a post, a bio, a company announcement, whatever I have. Your job is to produce 10 opening lines from it: - Each under 25 words. - Each ties the research to a plausible business problem, not just an observation. 'Saw you're hiring 6 SDRs' is an observation; 'Six new SDRs usually means ramp time just became your bottleneck' is an opener. - Label each line with its angle: observation-to-problem, data point, contrarian take, peer comparison, or timing. - No flattery openers, no 'quick question', no fake familiarity like 'Hope Q3 is treating you well'. After the 10 lines, tell me which two you'd bet on and why, in one sentence each. Before you write anything, interview me. Ask me these questions ONE AT A TIME, waiting for my answer each time: 1. What does your company sell, and what's the clearest outcome customers get? 2. Who is the prospect (role, company, industry)? 3. Paste the research you have on them — a post, bio, news item, anything. 4. What problem does your offer solve that this research might hint at? Once you have my answers, produce the 10 lines. If the research is too thin to support 10 distinct angles, say so and ask me for one more data point instead of padding with generic lines.

Best practices
Feed it recent, specific research — a two-week-old LinkedIn post beats a company About page every time.
If lines come back as compliments, reply 'tie every line to a business problem' and regenerate.
Keep the winning angle labels — over a few weeks you'll learn which angle style your market responds to.
Run several prospects in the same chat; the model keeps your offer context and gets faster per prospect.
Example: what this looks like in practice
An SDR at a 25-person RevOps consultancy targets Heads of Sales at Series A SaaS companies. She pastes a prospect's LinkedIn post about missing pipeline targets despite hiring two more reps. The model returns 10 lines across five angles; the strongest, labeled observation-to-problem, reads 'Two new reps and a missed pipeline number usually means the problem is upstream of headcount.' She uses it, gets a reply within four hours saying 'painfully accurate', and books a call that week. She now runs every priority account through the prompt before writing a word herself.

A good opener connects something specific about the prospect to a problem you solve, in under 25 words. It proves you did homework and gives them a reason to keep reading. Openers that fail are the ones that could be sent to anyone: greetings, self-introductions, and compliments with no business point attached.
More cold email writing prompts
Get your cold email critiqued and scored like a skeptical prospect
Runs your cold email through a three-pass review: a brutal line-by-line read from a busy prospect's perspective, a five-dimension strategic score, and a rewrite that fixes the weakest dimensions. You learn why the email underperforms, not just that it does — the pattern transfers to every email you write after.
Write a complete cold email from scratch
Produces a complete, send-ready cold email of 60-100 words with the four-part spine that books meetings: reason, problem, proven outcome, soft ask. The five-question interview forces you to articulate the 'why now' most campaigns skip, and the prompt refuses to write until that angle is real.
Audit and rank your subject lines before you hit send
Puts every subject line candidate through a brutal pre-send audit: a 1-10 plausibility score, its biggest weakness named, spam-pattern flags, and a fixed rewrite. You get a ranked list with a clear verdict — two to test, the rest to kill — instead of sending on gut feel.
