Write cold emails that feel like a 1-to-1 conversation

AI Skill of the Week | Issue #13

You just spent 20 minutes researching a prospect.

Found their LinkedIn.

Read their last post.

Spotted the funding round.

Identified the pain.

Then you opened a blank page… and wrote something that could’ve been sent to 10,000 other people 🤯

“I came across your profile and thought...” Delete.

“We help companies like yours...” Delete.

“It would be great to connect...” Delete.

It’s the generic copy trap.

Here’s the deal: only 5% of senders personalize every email — and they achieve 2–3× better results than everyone else.

71% of decision-makers say they ignore cold emails because of lack of relevance.

Not deliverability. Not timing. Relevance.

Luckily there’s a Claude skill to help us fix that.

🔍 What it does

The Cold Outreach Personalizer turns raw prospect research into messages that read like they were written for one person — because they were.

It follows the S.I.G.N.A.L. framework: every message must open with a real, verifiable signal (a post, a funding round, a new hire) and close with a soft, specific CTA — never a demo request on the first touch.

It also tiers your signals.

Tier 1 (funding, role change, product launch) → highest reply potential.

Tier 3 (liked a post) → flagged as weak before you write a single word.

No signal, no message.
