The Update contact field action allows you to automatically modify the information stored in a contact’s profile, without the need for manual changes.

This is a very useful tool to keep your data always up to date and make your segmentations more precise. It helps you further personalize your automation flows and ensure that contacts receive truly relevant messages.
For example, at the end of an onboarding sequence, you can update the custom field “Onboarding” to “Completed”. This allows you to trigger other flows automatically, based on always up-to-date data.
