In a recent LinkedIn post, Andrew Bolis discusses a critical pitfall in sales outreach that led to poor results despite using multiple data cleaning tools. Bolis shares his experience of facing a significant bounce rate, even after attempting to sanitize his lead lists.

He highlights the core issue: the distinction between data that appears “clean” and data that is truly “verified.” Bolis states:

I used 3 tools to clean my leads list and still got no replies to my outreach emails. After analyzing what went wrong, I found the problem: 22% bounce rate. From data that passed three validation checks. It turns out that “clean” isn’t the same as “verified.”

This experience, as detailed by Bolis, underscores the hidden costs associated with using subpar data. He points out the time lost in repetitive cleaning, tool switching, and re-verification processes, which he initially accepted as standard for outreach efforts.

The Hidden Costs of ‘Clean’ Data

Andrew Bolis argues that the common approach of using multiple tools for data preparation is inefficient and often ineffective. He elaborates on the frustration and wasted effort:

And the worst part? No one talks about the hidden costs bad data creates: Every “quick fix” costs hours, switching tools, cleaning CSVs, and verifying emails again. I thought this was just part of doing outreach…

Bolis’s perspective suggests that many sales professionals might be overlooking the true impact of data quality on their outreach campaigns, attributing poor performance to other factors like email copy or target audience.

Rebuilding the Workflow with Verified Data

The turning point for Bolis came when he overhauled his team’s workflow by adopting a single platform, Prospeo.io. He outlines the significant improvements achieved through this shift, emphasizing the benefits of real-time data refreshing and advanced verification checks.

Key Improvements with Verified Data

According to Andrew Bolis, the integration of Prospeo.io led to several key advantages:

• Data refreshed weekly, a substantial improvement over previous 60-day cycles.
• SMTP checks to confirm mailbox existence before sending emails.
• Automatic removal of risky catch-all addresses.
• Filtering of spam traps prior to data export.
• Identification of job changes before campaigns are launched.

Bolis emphasizes the direct impact of these features on campaign performance:

These features alone fixed most of our problems. ✓ Bounce rate dropped from 22% to under 2% ✓ Zero time cleaning CSVs or running lists through separate tools ✓ Higher email open rates and reply rates (more meetings booked)

He attributes the success solely to the change in data verification, noting that other elements like email copy, Ideal Customer Profile (ICP), and sending infrastructure remained constant.

A Unified Approach to Lead Generation

Andrew Bolis advocates for a consolidated approach to lead generation, contrasting it with the common practice of using disparate tools for searching, verifying, and sending. He explains his team’s current, more efficient process:

Instead of using multiple tools, we search once and send verified leads directly into our outreach. Most companies build lead lists from one database, verify them somewhere else, then send and hope. Prospeo combines search, verification, and deliverability protection in one place.

Bolis concludes his post by recommending that businesses still relying on multiple tools for their outbound efforts should consider testing a unified solution like Prospeo.io, suggesting it could significantly improve their outreach success rates.
