Best Use Cases
Ehsan's Growth Take
Instantly solved the infrastructure bottleneck of cold email: domain rotation and warmup. A 3-person SDR team using 30 domains with proper warmup outperforms a 10-person team on a single domain. The math is not close. But this is a volume tool, not a precision tool — pair it with Clay for personalization.
