🧱Cold Email Infrastructure Setup
Domain Strategy
Buy a separate domain or use a subdomain (e.g. tryb2bxclusive.com, get.b2bxclusive.com). This keeps your main brand domain safe from deliverability issues.
Domain Configuration Essentials
- SPF (Sender Policy Framework): authorizes your servers to send mail.
- DKIM (DomainKeys Identified Mail): ensures email integrity.
- DMARC (Domain-based Message Authentication): monitors spoofing.
Recommended Tools
- MxToolbox: for testing DNS configurations.
- Google Postmaster Tools: to monitor Gmail reputation.
- Microsoft SNDS: to monitor Outlook delivery.

Write Like a Human. Every line should push the conversation forward.
PASTOR Framework

- Offer: CTA to chat/learn more.
Core Email Rules
- Keep it under 5 lines.
- No attachments in the first touch.
- Use 1 clear CTA only.
📆Sequence Cadence
Example Sequence
| Day | Email Type | Intent |
|---|---|---|
| 1 | Short, benefit-led email | Hook curiosity |
| 3 | Social proof or 1-sentence case | Build trust |
| 6 | Question-based CTA email | Low-friction ask |
| 10 | Share a resource (video, guide) | Value first |
Multi-Channel Touches

- Bonus: Add a Loom video at Day 4–5.
📊Deliverability Optimization
DOs

Metrics & Target Ranges
| Metric | Target Range |

| Reply rate | 8–20% |

What to Test
