Overview
Sameer runs a cold email agency for B2B service companies that was struggling with email deliverability at scale. Before ListKit, his team faced a frustrating cycle: email accounts would burn out within 4 weeks, requiring constant warming of new accounts and disrupting campaign momentum. After implementing ListKit's infrastructure, his client went from booking 1-2 meetings per day to an impressive 5-7 meetings daily, with deliverability scores exceeding 98%.
The switch to ListKit not only improved performance dramatically but also streamlined operations. Sameer's team no longer needs to manage inbox setup and rotation, allowing them to focus on campaign strategy and business growth. The cost-effective pricing structure enabled them to double email volume without increasing expenses, creating a win-win situation for both the agency and its clients.
