Bought this for a cold outbound push. ROAS improved roughly 30% versus the lookalike audience we ran before. Bought it as part of a wider pediatric dentist doctor expansion into India. One column I'd add next refresh: secondary email.
Replaced an older vendor with this. Bounce rate stayed under 4% on a 1,000-contact email send. Bought it to scope a India territory in the pediatric dentist doctor segment. Sales team is happy.
