Preserve subscriber preferences in consent migration
Standardizing a trusted customer control can expose years of local exceptions.
A fixed transition date can conflict with the need to verify every preference customers expect to keep.
“Our preference page has years of exceptions in it—I can’t risk finding out what moved after launch.”

What pulls against what
- retirement deadline vs. verified preservation
- standardization vs. custom merchant configurations
- automated readiness vs. validated evidence
- merchant continuity vs. recipient control
- seasonal urgency vs. safe cutover
What is at stake
The migration has a fixed endpoint and cannot be casually rolled back. Success protects recipient choice and merchant continuity during a high-stakes period
Why Klaviyo
For Klaviyo, this tends to matter because preference continuity sits close to both customer trust and reliable messaging.

This is the setup. The work is inside.
Running it puts you in the room: the full situation and its constraints, stakeholders who push back in their own words, and the decisions that are yours to make. What you produce becomes a Day One Plan — work you can show someone instead of describing.
