Rebuilding Deliverability on a New Sending Domain
An eight-week case study from a real Klaviyo account: after a domain migration, we cut standard sends from 68K to 36K recipients, opens went from 27% to 38%, and revenue per recipient held flat. The layered core audience (engaged OR recent buyer OR recent browser), the provider-scoped exclusion that lifted Gmail opens 7 points at zero revenue cost, and the from-address mistake that bounced 24% of one send's Gmail volume.
