Cold Email Case Study: 838 Sends and Reported Engagement
Overview
Pearl Lemon’s internal Lemlist campaign reports 838 sends, an 80% open rate, a 10% click rate, a 1% bounce rate and 49 unsubscribes.
Results and measurement
Open and click tracking can include automated activity. The unsubscribes should not be described as negligible; replies, qualified meetings and sales need separate reporting.
Source: Pearl Lemon’s published campaign account. The figures are reported results, not an independently audited dataset.
Measurement reference: Mailchimp explains how Apple Mail Privacy Protection affects open tracking. This explains a measurement limitation, not whether this campaign contained automated opens.

Campaign Overview
Tool used: Lemlist
Campaign type: Cold email outreach + job board funnel
Purpose: Generate internal leads, test new frameworks, and refine cold email strategies
Key Performance Metrics
Reported internal campaign metrics
- 838 emails sent
- 80% reported open rate
- 10% reported click rate
- 1% reported bounce rate
- 49 unsubscribes
- The account describes positive replies and demos, without a reconciled total.
If 838 sends is the applicable denominator, 49 unsubscribes would be about 5.85%. Unique-recipient and delivered-email counts are needed to confirm the correct unsubscribe rate. Open and click tracking may include automated activity; comparable benchmarks and closed-sales attribution are not supplied.
