How LakeB2B Empowered a Leading Pharmaceutical Brand to Roll out a High-Engagement HCP Email Outreach Program

Executive Summary

A US pharmaceutical brand approached LakeB2B with a clear objective: engage a targeted audience of US healthcare professionals (HCPs) to promote awareness of a specific oral medication dosage, drive traffic to patient resources, and validate whether digital email outreach could deliver meaningful engagement within this prescriber segment. To de-risk investment and build the case for scale, the brand identified several areas for growth, which included:

• Engagement Precision: Clinicians receive high volumes of promotional content, making it difficult to surpass high engagement thresholds and connect with high-intent prescribers.
• Speed to Market: Launching a structured proof-of-concept program to deliver data-driven evidence quickly, while maintaining flawless data hygiene standards.
• Audience Identification: Success depended on locating and engaging verified, high-intent healthcare professionals at scale, without experiencing audience fatigue across repeated deployments.

The Solution Data-Driven Market Expansion

The pharmaceutical provider partnered with LakeB2B to access a stable, high-quality US HCP database. Using this information, the team launched a comprehensive initiative focused on three core pillars:

1. Strategic Audience Segmentation The team utilized verified prescriber data to move beyond generic outreach. They segmented audiences based on:

• Prescription Relevance: Isolating specific healthcare professionals within the exact therapeutic category relevant to the medication.
• Behavioral Engagement: Evaluating interaction patterns to match clinical content with clinician interests, such as safety and regulatory updates.
• Propensity Segmentation: Introducing a decile-based targeting framework at scale to separate audiences into higher-propensity and standard-propensity segments.

2. Multi-Channel Execution The marketing team activated the data across carefully structured deployment phases to reach prospective prescribers effectively:

• Pilot Campaigns: Deploying a three-part email proof-of-concept phase to build a shared evidence base and test channel responsiveness.
• Scale Deployment: Expanding the outreach program into a full-scale multi-segment email rollout following successful validation.

3. Value-Based Messaging: Increasing the relevance of each interaction through a clinical communication strategy that emphasized clinical utility, regulatory and safety resources, and patient cost tools over standard product claims.

Results and Key Outcomes

By utilizing targeted and intent-driven HCP data, the company successfully positioned itself for a long-term strategic rollout. Additionally, the client was able to achieve:

• Expanded Reach: Scaled outreach safely from an average of ~32,000 HCPs per pilot deployment to over 52,000 recipients simultaneously in the scale phase without diluting quality.
• Improved Engagement: Secured an average open rate of 23.78% and a 3.36% CTR during the pilot, with open rates consistently remaining above 22.5% at double the volume during scale.
• Enhanced Visibility: Gained strong momentum in the therapeutic segment, capturing an extended engagement window where HCPs revisited clinical email content 48 to 72 hours post-send.
• High-Value Conversion: Optimized conversions by maintaining a flawless 0% bounce rate across all 52,903 sends, preserving sender reputation and converting a trial engagement into a 52-campaign contract.

Conclusion

With LakeB2B’s verified US HCP database, the client reached the right individuals using relevant data, which not only boosted channel confidence but also maximized campaign performance, leading to a sustainable framework for future growth across a full-year contract partnership.
