The Cold Email Formula
Every high-converting cold investor email has 4 parts:
1. HOOK (1 sentence): Why you're emailing THIS investor 2. TRACTION (1-2 sentences): Proof you're worth meeting 3. ASK (1 sentence): Specific, low-commitment request 4. CLOSE (1 sentence): Easy next step Total: Under 100 words

Frequently Asked Questions
How many cold emails should I send?
20-50 highly personalized emails outperform 200 generic ones. Research each investor (5-10 min), personalize the hook, and track responses. At 10% response rate, 50 emails = 5 meetings. Quality over quantity always.
When should I send cold investor emails?
Tuesday-Thursday, 8-10am in investor's time zone. Monday inboxes are flooded from weekend backlog. Friday emails get buried before Monday. Morning timing catches investors starting their day.
Should I attach my deck?
No—use a trackable link (Docsend, Google Drive). Attachments can trigger spam filters and don't let you see if they opened it. Links let you track engagement and update the deck without resending.
How do I find investor emails?
LinkedIn, Crunchbase, fund websites, and email finding tools. Most VC emails follow firstname@fundname.com or first.last@fundname.com patterns. Tools like Hunter.io can verify. For angels, check their Twitter/LinkedIn bios.
What if they don't respond to my follow-up?
Move on—reach back out in 3-6 months with new traction. No response after one follow-up means not interested right now. Don't burn the relationship with excessive follow-ups. Significant new milestones justify a fresh outreach later.
Should I cold email partners or associates?
Both, but tailor your approach. Partners make final decisions but get more email. Associates are more responsive but need to champion you internally. For seed rounds, target partners directly. For Series A+, associates can be effective entry points.
