# Secure CFPB EcoLetter Delivery

> ABC Collections sends CFPB validation letters to a group of consumers.

## Real-World Example

ABC Collections sends CFPB validation letters to a group of consumers. The portal should generate secure EcoLetters, notify consumers, and later clean up temporary zip files used for download packages.

## How It Should Work

* It should create CFPB letter access only for the intended consumers.
* It should trigger the correct consumer communication after delivery.
* It should clean up temporary zip files after they are no longer needed.

## How It Should Not Work

* It should not expose secure letters across creditor boundaries.
* It should not leave temporary bulk download files around indefinitely.
* It should not mark letters delivered before the secure records exist.

## Developer Notes

* CFPB template setup is the user-facing setup page; secure delivery is the background behavior behind delivery.
* EcoMailbox and campaign tracking can be affected by letter delivery and reading behavior.
* Secure EcoLetter notifications use the same background email/SMS delivery and webhook tracking rules. See [Communication Delivery & Webhooks](/portals/creditor/background-processing/communication-delivery-and-webhooks).
