Did the job for our campaign. Cross-checked 50 entries against Google Maps and 47 matched cleanly. Bought it to underpin a United States popshelf store locations campaign. One column I'd add next refresh: secondary email.
Thanks for the detailed review, the points you raised are on the refresh checklist for the next pull. If you want the gaps fixed sooner than the next refresh, open a support ticket and we'll spin a one-off pull.
