Customer email-domain auto-mapping for feedback identity
Map incoming support requests to the right customer record by email domain so product sees account context without a cleanup pass.
Why this can grow a startup
Feedback gets weaker every time a team has to re-attach the company behind it. Automatic domain mapping keeps the request connected to the buyer from the first handoff, which means product, success, and support can judge the request with the right account context already in view. That shortens triage time and makes it easier to act on feedback before the moment cools off.
Company example
Linear's Customer Requests docs say customers created through integrations are mapped using the customer's email domain when the first request is created.

When to use it
Use this when Support, Product, Customer Success is relevant to feedback loop, identity mapping, b2b and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
