Domain rotation planning
Plan domain count so rotation keeps per-domain volume inside caps.
At higher volumes, spreading sends across enough domains keeps each one under its daily cap and limits the blast radius when a domain needs replacement.

Model the send load.
Rotation here means capacity distribution and replacement coverage, not evading reputation. Each domain still needs DNS authentication, readiness checks, and launch-gate approval, and replacement workflows handle domains that degrade.

Monthly emails
30,000
10,000 prospects x 3 touches.
Daily send requirement

Spread across 5 send days/week.
Recommended inboxes

25 emails/inbox/day cap.
Recommended domains
19
3 inboxes/domain by default.
Infrastructure caps
- SMTP IP capacity
- 3
- Domain daily cap
- 100
- IP daily cap
- 3,000
- Warmup assumption
- 30 days
Per-IP utilization should stay below 80 percent before adding traffic. Scale horizontally with more IPs or domains before raising inbox caps.
Cost assumptions
Domain registration, taxes, discounts, support tiers, and real Microsoft/Google reseller SKUs can change the final quote.
Readiness notes
- Treat this as a planning estimate, not a quote or deliverability guarantee.
- Readiness gates, seed-placement evidence, and fresh SMTP/IMAP smoke tests still decide exportability.
- GTM-managed shared SMTP capacity; IP count is a planning signal, not a line item.
Common questions
Does rotating domains improve deliverability?
Not by itself. Rotation limits how much volume any one domain carries and makes replacement cheaper when a domain degrades. Placement still depends on authentication, content, targeting, and list quality.
How many spare domains should a rotation plan include?
Plan at least the calculated domain count plus replacement headroom. Registering a small buffer ahead of need avoids waiting on domain age and DNS propagation when a swap is required.
