The Problem
The PR agency needed massive-scale lead generation in a very short window. This required sending millions of emails while maintaining deliverability, reply rates, and positive sentiment.
What We Did
Hyperke ran hundreds of unique tests using daily feedback to adapt and adjust three broad variables: offer, angle, and audiences. The campaign was backed by a reliable email delivery engine leveraging Google, Microsoft, and SMTP inboxes with 24/7 health monitoring, 1:1 redundancy, aged domains, and tens of thousands of email inboxes each sending 10-30 emails per day.
The Results
In just 2 weeks, the campaign generated 3,513 leads from 2.6 million cold emails sent. The campaign achieved a 3.21% overall reply rate and a 7.28% positive reply rate at scale, demonstrating that high-volume outreach can maintain quality with meticulous planning and infrastructure.
Common Questions
Hyperke sends 8M-15M cold emails every month, sending 100,000 emails for a few clients and millions of emails for others. Our systems can support whichever level of scale you require.
