The Store Leads database does not include any personal information, so customers often use other data vendors to find contact information for the stores in our database.
Since this is such a common use case, we've started integrating with personal data vendors to make things easier. Our new Apollo.io integration lets you see Apollo.io contact data when using Store Leads. You can also manually create CRM contacts from Apollo.io data and we'll soon be adding the ability to automate creation of contacts using workflows. Stay tuned for more news here.
Apollo.io provides some contact data for free but you'll need to sign up for a paid plan on their site if you'd like to access a lot of data.
