With Yesware's Contact Enrichment feature, you can see the latest information for the prospects and customers that you're reaching out to. Yesware automatically creates Contacts for people you're emailing with. Once the Contacts are created, clicking the enrich button will display more information on that person. Enrichment credits are an add-on to your existing Yesware plan. 

Enriching Contacts in the Yesware app site: 

Access your Contacts page in our app site to view all created Contacts. On the right side, click "Enrich Data" to display the additional information. When the button is clicked, we will use a credit and display both the current profile as well as the enriched. Selecting "save" will amend the existing Contact with that additional information.
