Deliverability Technical Architecture

Domain Isolation

Utilize secondary domain handles dedicated exclusively to cold outreach to protect corporate primary domain reputation.

Authentication Protocols

Configure valid SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication) records across all sending domains.

Warmup & Sending Limits

Enforce a 3-4 week automated domain warmup ramp and limit daily sending volume per inbox (e.g., maximum 30–50 cold emails/day/inbox) to maintain high deliverability scores.
