September 2025 Release Notes: Quality over Quantity

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

📈 September 2025 RevenueBase database stats:

• Business contacts: 323 million (Net Growth: -5 million)
• Companies: 63.8 million (Net growth: +1.3 million)
• Business emails: 59 million (Net growth: -0.3 million)
• Mobile numbers: 43 million (Net growth: -0.9 million)

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• 1 million cellphone numbers removed that are no longer valid.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.
• Quality enhancement initiative: retired contact records with no updates possible (i.e. private Linkedin profiles) in 12+ months
• Email matching improvements: Deployed new corporate email-pattern matching to increase discovery and coverage across the database.
• LAST_UPDATED_AT now reflects the most recent verification of job title/employer via trusted sources (typically LinkedIn), even if unchanged. Email verifications no longer update this field. Those are now exclusively tracked in EMAIL_UPDATED_AT.

🧩 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’s sometimes limits access to job-experience fields, or people delete their profiles. While we can re-verify emails anytime, we now age out contacts whose job experience hasn’t been re-verified within 12 months, even if their email was recently verified.

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!
