Cold Email Draft Diagnosis and Rewrite
Paste a cold email draft and get the one problem killing replies, a short single-ask rewrite, a better subject line, and a change log.
Before & after
Same prompt, same agent — the only difference is the skill.
Here's a polished version of your email: Subject: Exploring a Potential Partnership Opportunity Hi Sarah, I hope this email finds you well! My name is Alex and I'm the founder of a company that specializes in helping businesses like yours streamline their operations and unlock new efficiencies. We've worked with several companies in your industry and have seen tremendous results. I'd love to hop on a quick 15-30 minute call to learn more about your current challenges and explore whether there might be a fit. Would you have some time this week or next? Happy to work around your schedule. Best regards, Alex
SUBJECT — pick one 1. Your returns page is costing you reorders 2. Question about Shopify returns 3. 40% of your returns could be exchanges REWRITE Hi Sarah, I bought from you last month and returned a jacket. The refund was quick — but nothing offered me an exchange, so you lost the reorder instead of keeping the revenue. We turn that flow into an exchange-first path. Two DTC brands running it kept 38% of refund requests as exchanges. Worth 15 minutes? Alex WHAT WAS WRONG • Subject said nothing — "partnership opportunity" is what every spam email says • Opened with you, not her: three sentences before her name's problem appeared • Three asks (learn more / explore fit / find time) collapsed to one • "Tremendous results" with no number — replaced with the 38% figure • "Hope this finds you well" and "streamline operations" are filter bait • Cut 148 words → 63
About this skill
You wrote the cold email, it seems fine, and nobody replies. Most of the time the cause is one fixable thing: the preview line is about you, there are three asks, or the subject line looks like an ad. Paste your draft and this skill finds that one problem, rewrites the email around the prospect, and tells you what changed and why.
What it does
- Names the single biggest reply-killer first: opener, ask, length, proof, or subject line
- Rewrites the first line to be about the prospect, because that line is what shows in the inbox preview
- Applies a swap test to your personalization: if the opener would still work with another company's name in it, it gets replaced or flagged
- Cuts several asks down to one low-effort question and swaps the 30-minute demo request for an easy yes/no
- Flags spam-trigger wording, unsupported claims, attachments, extra links, and broken merge fields like {{first_name}}
- Keeps your real facts and voice, and uses [brackets] for anything it would otherwise have to make up
What you get
The main problem in one line, a rewritten subject line and body with a word count, a short list of what changed and why, and placeholders to fill before you send. Short questions get short answers. A whole sequence gets reviewed step by step.
Best for
Founders, SDRs, AEs, agency owners, and consultants who write their own B2B cold email and want a final check before it goes out, or before it becomes the template for a whole campaign.

name: cold-email-draft-rewrite
description: Diagnoses a pasted cold email draft, names the one problem most likely killing replies, and rewrites it into a short, specific, single-ask email with a new subject line and a change log. Covers subject and preview line, opener relevance, proof, ask friction, length, spam-trigger wording, and broken merge fields. Use when the user says "can you tighten this cold email", "review my outreach before I send it", "rewrite this so it doesn't sound like spam", "nobody replies to my cold emails", "my emails keep getting ignored", "make this sound less salesy", "fix step 1 of my sequence", or "is this email too long".
