The Strategic Partnership Between Pipl.ai & Stimuli

Strengthening Cold Outreach Automation – The Strategic Partnership Between Pipl.ai & Stimuli

Building a More Scalable and Data-Driven Outreach Platform Together

Cold outreach agencies rely on Pipl.ai’s automation platform to execute large-scale, highly personalized email campaigns. As the demand for better automation, analytics, and workflow efficiency grew, Pipl.ai needed to enhance its API, optimize campaign reporting, and improve its infrastructure to help agencies scale more effectively.

This is where our partnership began.


As an operational partner, Stimuli collaborated closely with Pipl.ai’s development team, helping to enhance automation capabilities, expand API functionalities, and improve campaign tracking. However, this was not a one-sided effort—Pipl.ai played a crucial role in shaping and executing these enhancements, ensuring that agencies could fully benefit from the system improvements.


Through tight collaboration, continuous feedback loops, and shared expertise, we worked together to refine key platform functionalities, making Pipl.ai more powerful, scalable, and agency-friendly.

Challenges in Scaling Pipl.ai for Outreach Agencies

As agencies expanded their outreach operations, several key challenges surfaced that required both technical improvements and strategic automation upgrades:

🔹 API limitations – Agencies needed more automation-friendly API functionalities to track campaign performance, inbox health, and lead engagement in real time.
🔹 Inbox-level performance insights – Without clear inbox health tracking, agencies struggled to identify burned inboxes, deliverability issues, and low-performing accounts before problems escalated.
🔹 Data inconsistencies – Variations in lead tracking and reporting discrepancies across multiple campaigns created operational inefficiencies.
🔹 Manual reporting processes – Agencies had to manually extract, analyze, and consolidate campaign data, making reporting time-consuming and inconsistent.
🔹 Decentralized webhook management – Lack of structured webhook tracking meant agencies had to track API events manually, leading to missed campaign insights.

These challenges weren’t just technical—they directly impacted agencies relying on Pipl.ai to manage and optimize their outreach campaigns.

Solutions Developed Through Our Partnership

1. Expanding Pipl.ai’s API Capabilities

One of the most critical enhancements was upgrading Pipl.ai’s API infrastructure to support seamless automation at scale. Together, we:

Developed new API endpoints for webhook automation, including GET & DELETE operations, improving tracking and management.
Enhanced campaign analytics APIs, ensuring real-time updates, better filtering, and improved data accuracy.
Enabled inbox-level performance tracking, allowing agencies to monitor open rates, reply rates, and deliverability per inbox.
Refined campaign status tracking, ensuring accurate updates when campaigns are paused, completed, or modified.
Implemented “Last Activity Timestamps” to allow agencies to better segment and manage active vs. inactive campaigns.

📌 The Result: A more powerful, developer-friendly API that gives agencies more control, visibility, and automation capabilities in their outreach workflows.

2. Optimizing Campaign & Lead Performance Tracking

To enhance tracking and improve how agencies measure campaign effectiveness, we worked alongside Pipl.ai to:

Implement real-time campaign performance logs, ensuring accurate sent, reply, and bounce rate tracking.
Design a structured data migration workflow, allowing agencies to consolidate and analyze historical campaign data without inconsistencies.
Improve campaign metadata retrieval, making it easier to categorize, compare, and analyze outreach performance across different client accounts.
Automate campaign reporting workflows, significantly reducing the time spent on manual data tracking.

📌 The Result: Agencies now have instant access to accurate campaign data, making their outreach more data-driven, scalable, and efficient.

3. Advanced Webhook Management & Automation

Webhook automation is a key component of scaling outreach operations, and together, we:

Implemented a centralized webhook management system, allowing agencies to track API events in real time.
Debugged webhook failures, improving automation stability and reducing data inconsistencies.
Refined webhook response structures, making integration seamless with third-party tools like Airtable, Slack, and Zapier.

📌 The Result: A fully automated event-tracking system, ensuring that agencies never miss crucial campaign updates.


4. Inbox Health & Performance Tracking

A healthy inbox is critical to maintaining high deliverability rates, and Pipl.ai needed standardized tracking across agencies. Together, we:

Defined key inbox health metrics, allowing agencies to monitor individual inbox performance over time.
Designed automated alerts for inbox failures, ensuring no campaigns are sent from flagged inboxes.
Developed custom API automation for inbox cycling, allowing agencies to dynamically rotate inboxes to protect sender reputation.

📌 The Result: Better inbox management, improved deliverability, and reduced risk of inbox burnout for agencies.

5. Campaign Reporting & Insights Dashboard

To make reporting easier and more actionable, we worked closely with Pipl.ai to:

Develop automated reporting workflows, significantly reducing the need for manual data extraction and analysis.
Implement bulk campaign stats export functionality, making it easier for agencies to analyze large-scale campaign performance.
Introduce inbox performance heatmaps, helping agencies detect inbox deliverability issues before they escalate.

📌 The Result: Agencies can now visualize and act on campaign performance data in real-time, making reporting a proactive, rather than reactive, process.
