The challenge for Pearl Lemon Leads was to continuously test, validate, and refine cold email strategies internally to ensure every system delivered to clients was high-converting. This involved generating internal leads and outperforming industry norms for open and click rates in cold email outreach.
Pearl Lemon Leads utilized Lemlist for internal cold email outreach, running multiple ongoing sequences including newsletter-style follow-ups and job board funnel sequences. Their approach focused on strong deliverability through verified infrastructure, time zone sequencing, and zero spam trigger language. They also implemented a clear reason for outreach and conversational, relevance-driven messaging.
The internal campaigns achieved an 80% open rate and a 10% click rate, significantly exceeding industry averages of 30-45% open rates and 1-3% click rates. These campaigns resulted in dozens of positive replies, booked demos, and direct conversions into calls, even from completely cold audiences. They also maintained minimal churn with only 49 unsubscribes for the volume.
