Description

Every marketing system depends on accurate consent data. When someone subscribes, every relevant attribute and list needs to update immediately. When someone unsubscribes, the same applies in the other direction. Without automation, these updates rely on manual processes, integrations, or scheduled jobs that can fall out of sync. This use case puts it on autopilot. The moment any consent-related attribute changes, a set of cascading updates fires automatically: the unsubscribe flag is set, the newsletter list is adjusted, and the change is logged as an event for full traceability. Sender reputation, compliance, and data consistency are all protected in real time.

How it works in practice

A contact fills in a sign-up form and their Consent email attribute is set to TRUE. The automation fires immediately: Unsubscribed from emails is set to FALSE, the contact is added to the Newsletter list, and a Consent email change event is logged with the value TRUE. That contact can now receive emails. Three months later, they click an unsubscribe link. The Unsubscribed from emails attribute flips to TRUE. The system catches this change and updates Consent email to FALSE to keep both attributes in sync. A second automation detects the change to Consent email = FALSE, removes the contact from the Newsletter list, and logs both a Newsletter unsubscribe event and a Consent email change event. Every step is recorded. The data is consistent. No one receives an email they did not consent to.

1

When the contact gives email consent: When Consent email is set to TRUE, the system automatically sets Unsubscribed from emails to FALSE, adds the contact to the Newsletter list, and creates a Consent email change event with the value TRUE. This confirms the consent and activates the contact for email communication.

2

When the contact unsubscribes: When Unsubscribed from emails changes to TRUE, the system immediately updates Consent email to FALSE. This ensures both attributes stay consistent and that no further marketing emails are sent to this contact.

3

When email consent is revoked: When Consent email changes to FALSE, the system removes the contact from the Newsletter list and logs two events: Newsletter unsubscribe and Consent email change with the value FALSE. This ensures full traceability of the consent change and keeps records accurate.

Prerequisities

Set up the Double Opt-in or Double Opt-in with Discount Code use case before activating this flow. Subscription management depends on those opt-in flows to populate the Consent email attribute correctly.
Review the flow against your existing system setup and subscription management process before going live.

Recommended data structure

Contact Attributes

A contact attribute is a data field stored on the contact's profile, used for segmentation, personalization, reporting, and automation.

Attribute name

Lists

A list is a flexible group of contacts that can be managed independently of segment rules.
