Cold Email

The cold email skill writes one highly personalized email per lead. It researches before writing, applies a 6-point quality gate, and only returns the email when it passes. If it doesn’t pass, it revises automatically.

The 6-point quality gate

Every cold email Striker writes is checked against all six before delivery:

Check	Rule
1. Specific mention	References something real and specific about the recipient or their company
2. Subject length	Under 6 words. Curiosity gap or direct reference. Never vague.
3. Body length	Under 150 words total
4. CTA count	Exactly one ask. Never two.
5. Reads naturally	Sounds like a person wrote it, not a template generator
6. No banned words	Zero: synergy, leverage, innovative, revolutionary, cutting-edge, game-changing

Fails any check → revised. Passes all six → returned.

Email structure

Subject: [Under 6 words — specific or curiosity gap]

Line 1: Specific reference to them.
         Something real: a recent announcement, a job posting, a hire,
         something they published, something their company just did.

Lines 2–3: Your pitch framed as their problem.
            What you do, positioned as the solution to what they're
            facing right now. Not features. Not capabilities. Their problem.

Line 4: One CTA. One question. One ask.
         "Worth a 20-minute call this week?"
         "Open to a quick demo Tuesday or Wednesday?"

Subject: Your Series B + the ops bottleneck

Saw Acme Corp closed the $42M Series B last week — congrats.

Most B2B teams at your stage hit the same wall right after a
raise: the manual ops work that ran fine at 50 people starts
breaking at 180. Fixing it without another ops hire is solvable.

Worth 20 minutes this week to see if it's relevant?
