Domain rotation is not a trick. It is a strategy to reduce risk, protect your primary domain, and keep stability over time.
1. Secondary domains with correct DNS
Configure SPF, DKIM, and DMARC on every secondary domain before sending. Without them, deliverability collapses.
2. Volume distribution by health
Do not send the same volume on every domain. Adjust based on replies, bounces, and spam reports.
3. Clear rotation rules
Set daily limits per domain and create alerts when inbox rate drops.
4. Protect the primary domain
Your brand domain should run at controlled volume. Its reputation is more valuable than raw volume.
