    What this skill does

    Generates 3 variations of a personalized cold email for one specific prospect, based on your ICP (ideal customer profile) and the prospect's site. Each variation tests a different hook: pain point, social proof and curiosity.

    When to use

    • 1:1 outbound to a qualified prospect
    • Re-engaging a lead that went quiet
    • Asking for an intro to someone specific

    Don't use for:

    • Mass email (it will read as spam)
    • Newsletters (use your provider)

    How it works

    1. You give it: the prospect's URL, your ICP in 1 sentence, your offer in 1 sentence
    2. The skill reads the prospect's site (if web search is enabled)
    3. Identifies 1 personal/company hook that justifies reaching out now
    4. Generates 3 email variations (≤ 90 words each)
    5. Suggests the subject line for each variation
    6. Includes a signature block with no fluff

    Copy principles

    • Line 1: why HIM, why now (not you)
    • Line 2-3: what you know about his problem
    • Line 4: what you do, in 1 concrete sentence
    • Line 5: a specific ask (15min? deck? intro?)
    • No 'I hope this finds you well'. No 'just following up'.

    Output example

    Variation 1 — Hook: pain point
Subject: Still sending cold email by hand?

Hi João, I saw you posted an SDR role last week.
Most solo founders burn 10h/week doing the SDR's job
before they hire one. We built a Claude skill that
cuts that work down to ~1h/week.

Up for 15min this Thursday so I can show you?

    Pre-reqs

    None required. If you enable Web Search in Claude, personalization gets much stronger (the skill can read the prospect's site).

    Build.

    Work.
