⚙️ Pillar #1: Technical Infrastructure

Step-by-Step DNS Setup (Using Spaceship)

  1. Buy your domain

    💰 \[Pro Tip] Always buy additional secondary domains for cold email to protect your primary (sacred) domain from reputation damage.

  2. Set DNS Records (Critical for Inboxing)

  3. DNS Setup Example

Record Type Host/Name Value
Verification TXT @ Provided by ESP (Google Workspace, etc.)
MX Records MX @ Provided by ESP (multiple records with priorities)
DKIM TXT google._domainkey Provided by ESP
SPF TXT @ v=spf1 include:_spf.google.com ~all
DMARC TXT _dmarc v=DMARC1; p=quarantine; rua=mailto:[email protected]
