Helpful for some of the use case, not all. Email population was patchier than I expected from the listing. Bought it as the seed list for a speedliner locations outbound push in United States. Asked support how to flag the closed-storefront rows.
Sorry the file didn't fully land for you, we'd like to dig into the specific rows that failed and refund or re-export them for you. Please file a Support ticket (Help menu in your dashboard) with the failing row IDs — we'll either refresh the export or credit the bad rows the same day.
