Cold Email Lessons from Domain Outreach

Context

I’ve sent roughly 3,000 cold emails across 18 domains over the last few months. The results aren’t earth-shattering — a few replies, zero sales yet — but the learnings are valuable.

What I’ve learned

1. Named emails outperform generic by a wide margin

Sending to info@company.com is noise. The email gets opened at maybe half the rate of a named contact, and even when opened, nobody at info@ is empowered to spend $500–$5,000 on a domain.

Personal emails to founders and CEOs are the only contacts worth pursuing for domains in the $300–$2,500 range. The decision maker is the one who writes the check.

2. Dedup is non-negotiable

I contacted Cerebras 5 times about ChipWe.com over 3 months. Not intentional — I just kept generating new contact lists without checking the tracker.

A simple CSV-based dedup before every send would have prevented this. Now it’s a mandatory pipeline step.

3. Human reply rate is the only metric that matters

Delivery rate, open rate, click rate — none of those pay the bills. The number of humans who reply saying “tell me more” or “not interested” is the signal.

My rate is currently below 1%. That’s either a problem with targeting, messaging, or pricing. Probably all three.

4. One follow-up at day 5-7 is worth sending

A single follow-up to non-responders generates about 30% of total replies. Anything beyond one follow-up is noise.

5. BIN × 1.25 as the ask price

My current strategy: set the outbound ask at 1.25x the BIN price listed on marketplaces. This leaves room for negotiation while anchoring above the floor.

What I’d change

• Better targeting — score companies by fit before emailing, not after
• More research per contact — a personalized line about their business would outperform my current template
• Tighter pricing — $299 and $795 domains don’t justify the email; focus on $1,495+ names
• More patience — domain sales are a numbers game with long tails

The math

At my current volume (500 emails/month), at $795 average price, with a 0.5% conversion:

• Expected sales: 2.5/month
• Revenue: ~$2,000/month
• Cost: $0 (free email tiers)

The math works if I can reach 0.5% human-to-sale conversion. I’m not there yet, but I know the direction.

Tools I use

• Brevo / Resend / Mailgun — 500 free emails per day across all three
• Throttled rotary sender — custom CLI that rotates providers and enforces rate limits
• Domain outreach tracker — CSV + Neon DB for dedup and history
• MCP outreach tools — for contact management and status tracking

FAQs

Q: How many cold emails should I send per day?

A: Start at 20-30/day per domain. Scale up only when replies come in. Volume without personalization wastes good domains.

Q: What’s a good reply rate for domain cold email?

A: 1-3% is healthy. Above 5% means you’re doing something right. Below 1%, change your subject line or targeting.

Q: Should I follow up if no one replies?

A: Yes. One follow-up on day 5-7. If still nothing by day 30, route the domain to auction.
