After purchasing you can login to your DataValidation account and access the Lists page. "View List Details" for any list that has been uploaded or is in a linked account.
Click the "Download" button inside your list details and you'll be directed to a page where you have the option to "Upload Results" back to your MailChimp account.
*Please Note: If you have linked a MailChimp account to DataValidation you will need to "Upload Results" to get your cleaned list re-imported to MailChimp. This is very important.
If you are an Email Assurance customer, you will need to "Upload Results" to get your cleaned list back into MailChimp. This only needs to be done for your very first validation and then your MailChimp lists will be updated on a regular occurrence without any assistance from you.
Right now, only customers who have a MailChimp account can link an account to DataValidation and be eligible for Email Assurance. Want to request that we add your ESP? Email firstname.lastname@example.org.
