Unlimited Scaling via 'Warmup Bundling': Instantly tacticaly disrupted the cold email market by attacking the 'Delivierability' bottleneck. Their growth engine was 'Unlimited AI Warmup'—including account warmups for an unlimited number of domains in a single subscription. This tactical move directly appealed to lead-generation agencies who previously had to pay 'Per Account'. By aligning their pricing with 'Infinite Scale', they became the default choice for the highest-volume senders, driving massive word-of-mouth growth within the performance marketing community.
