Identity resolution is only available on Business tier plans. You can use it with or without Customer Studio.
After Hightouch runs identity resolution (IDR) on your graph, Hightouch outputs tables into your warehouse so they can be used for any business need.
Your marketing team can use them for paid campaigns, your sales team for deduplicating outreach efforts, or data scientists for fraud dection.
The output of IDR can also helpful in constructing models or parent models in Hightouch.
Hightouch creates two output tables:
A resolved table consisting of every row from your input models (<your_output_table>_resolved)
This table has the columns: ht_id, model_pk, and model. The model_pk is the primary key from your model and the model is the model slug.
This table has a column for each identifier you have mapped in your project. If the model doesn't have a column for that identifier, the value is null.
If you need to select just one identifier from a user profile, the resolved output table provides every identifier for all users across all models, along with a HT_ID that can be used to identify which identities should be merged together.
This table gives you full control over how you choose which identifier to use on an identity, for example:
most frequent email
most recent user id
most recent device id
The resolved_identities table collapses all the merged users into a single row with multiple identifiers in an array (for example ['kevin.tran@gmail.com', 'kevin@hightouch.com'].)
This gives a unified view of all the user profiles and their associated identifiers.
