1. Create a new smart list in Marketo
This will hold your contacts that pass through the Enrich skill in Drift Email.
2. Add "Data Value Changed" filters
Add two "Data Value Changed" filters to your smart list. One will track the attribute "Job Title" and the other will track the attribute "Phone Number".
If you've set up your Enrich skill in Drift Email to write to any secondary fields in Marketo, you can add filters for those attributes as well.
You can change the Date of Activity to whatever date limit you feel is relevant. If you've just turned on Enrich, you may want to stick with the past 30 days.
3. Add Source constraints
Specify the Source as "Web service API." Make sure to do this for each attribute you're tracking.
Note: if you have multiple integrations that are writing to these fields using the API, you may not be able to distinguish which contacts are being enriched by Drift Email compared to your other services.
4. Set the rule logic to "Use Any Filters"
Make sure that you have the "Use Any Filters" logic applied to your smart list. This will ensure that the list pulls a contact if any attribute on your smart list is changed (otherwise, a contact will need to have all those attributes changed in order to be added to your list.
