What it does
You share the body of a cold email or describe its message. Claude drafts several subject line options that read like a note from a colleague rather than an ad, mixing personalized and curiosity-driven styles. You get a shortlist to test.
Who it’s for
A good fit for marketers, founders and anyone promoting a business and writers, coaches and content creators.
Do you need to code?
No. You can use this without writing or editing any code.
How to install
Add it to Claude as a skill. Download the skill folder from its source page, zip it, and upload it in Claude’s settings under Skills. See the step-by-step guide.
Safety note
Suggests a paid third-party tool (ColdIQ) to source personalization details for subject lines.
As with any add-on, only install skills from sources you trust, and read what it does first.
