# What is closing the loop on customer feedback? | Annsa

> Closing the loop means telling the customer who gave feedback what happened because of it: what you changed, what you shipped, or why you won't.

Glossary · Close the loop

Closing the loop means telling the customer who gave feedback what happened because of it: what you changed, what you shipped, or why you won't. The strongest version names their original words, so they know their feedback was read.

## In practice

In March a customer asks for CSV export of invoices. In June you ship it. You write to that customer: "In March you asked to export invoices to CSV. It's live under Billing, Export." That message [closes the loop](https://annsa.ai/customer-feedback-management/customer-feedback-loop).

This isn't the same as [release notes](https://annsa.ai/glossary/release-notes). Release notes announce to everyone. A closed loop speaks to the person who asked.

Bain splits it in two. The inner loop is following up with one customer. The outer loop is fixing the cause so the next customer doesn't hit it.

## How to do it

1. Keep who asked for what, in their words.
2. When work ships, find everyone linked to it.
3. [Write each person a short note](https://annsa.ai/customer-feedback-management/closing-the-feedback-loop): what they asked, what changed, where to find it.
4. Have a person check it's true, then send.
5. If you decide not to build it, say so and why. That closes the loop too.

## Common mistakes

- Sending a generic changelog email and calling it closed.
- Promising a fix in the follow-up that nobody has decided to build.
- Telling a customer something shipped when it only merged. A wrong notice is worse than none.

## What changes in AI-first products

Agents ship fast, and the people who asked rarely hear about it. Drafting the note is cheap now; knowing who asked and checking it's true still matters. When a job ships, Annsa's [Share Back drafts a note](https://annsa.ai/learn/share-back) to each person who asked, quoting their feedback. A person reviews and sends it; auto-send is off by default.

## Questions people ask.

### What is closed-loop feedback?

A practice where a company follows up with customers who shared feedback, acts on what they said, and tells them the result.

### Who should you follow up with first?

Bain names customers with an unresolved issue, customers who gave constructive ideas or questions, and customers angry enough that the relationship needs repair.

### How fast should you close the loop?

Bain says follow-up should happen quickly and warns that weeks of delay block learning. It gives no fixed number of hours.
