First impression after the download: Dedup pass only flagged 1.2% — cleanest dataset I've worked with. Bought it as the seed list for a gym outbound push in Saudi Arabia. Money well spent.
Tried three vendors before this. ROAS improved roughly 30% versus the lookalike audience we ran before. Bought it to scope a Saudi Arabia territory in the gym segment. Will be the default vendor for us now.
Loaded the file the morning we got it. Encoded UTF-8 with no character-set surprises in Excel. Bought it as part of a wider gym expansion into Saudi Arabia. Saved us hours of manual cleanup.
