The client: A product analytics SaaS whose outbound had quietly stopped working.
The client assumed their messaging had gone stale. Open rates had fallen from 40% to 11% over four months while nothing about the copy or the list had changed.
When open rates decay steadily while everything else stays constant, the cause is almost never creative. It is reputation. The emails were being delivered — to the spam folder.
Secondary domains isolate reputation risk from your real business email.
p=none with no reports means you are flying blind on authentication failures.
List hygiene at send time keeps bounce rate under 2% and reputation intact.
The copy is the visible part. Underneath it sits the infrastructure that decides whether anyone ever sees it.
A steady decline in opens is an infrastructure symptom, not a copy problem.
Never send cold email from the domain your team uses for real business mail.
If you are not seed testing weekly, you will find out about a placement problem far too late.
Placement recovered to 90%+ and the same untouched sequence produced a 52% open rate — the campaign had never needed new copy.
