To manage your contact base effectively, you need to know which data points you can control and which ones are handled automatically by the system.
Think of a contact profile as a mix of flexible details and hard facts. Some information, like a phone number or a custom tag, is fluid and can be updated by you or your team at any time. Other information, like the “IP address” or the "Last Seen" timestamp, acts as a system record that tracks contact behavior automatically. Understanding this distinction is key to setting up accurate automation and maintaining clean data.
Below you will find the list of standard attributes that can or cannot be updated using the methods described in the "How to Update an Attribute" article.
