Your RevenueBase August 2025 release is here wherever you get your RevenueBase data.

📈 September 2025 RevenueBase database stats:

As part of a targeted quality-enhancement initiative, we performed more extensive cleanup this month (details below).

⭐ Data Quality Metrics:

Email re-verification rate: 98.18% verified within the last 60 days.
Contact data freshness: 84.27% of job experiences verified on LinkedIn within the last 90 days.
Company data accuracy: 89.11% of company information verified by trusted sources in the last 90 days.

🔧 Data Improvements:

9.2 million contacts removed – keeps your lists clean by removing people who recently left their job.
2.1 million email addresses removed that no longer pass our deliverability checks, keeping your email sends above 95% deliverability.
1 million cellphone numbers removed that are no longer valid.
Email coverage expanded by adding contact emails to additional companies.
Data quality enhancement initiative: Implemented automated logic to retire records with no updates for 12+ months, improving overall dataset quality. We plan to progressively shorten this deprecation window in upcoming releases to maintain fresher data.
Email matching improvements: Deployed new corporate email-pattern matching to increase discovery and coverage across the database.

🧩 Technical notes:

The contact-volume reduction reflects our commitment to data quality over quantity.
The enhanced email-matching patterns are already showing improved results and will be reflected in subsequent releases.
LinkedIn has instituted additional anti-scraping protections on public profiles, which can intermittently limit access to job-experience fields for extended periods. While we can re-verify emails at any time, we have chosen to “age out” contacts whose job experience hasn’t been re-verified within the past 12 months—even if their email was recently re-verified. We will consider adjusting the 12-month cutoff based on customer feedback.

What’s coming up:

We will officially be launching our email verification SaaS app. You can get beta access today by creating a free account here. If you’re already an email verification customer, don’t create a new account. You can simply just reset your password here.

October’s release: direct data feed subscribers will automatically get the link to people’s linkedin profile pics added to their deliveries.

Thank you for choosing RevenueBase! Stay tuned for more updates!
