SalesIntel uses human verification. Why verify again?

SalesIntel's researchers re-verify contacts on a 90-day cycle. Between cycles, people change jobs and emails become invalid. Truelist provides a real-time check right before your campaign.

How much stale data accumulates between SalesIntel's verification cycles?

B2B contacts change at roughly 25-30% per year, or about 6-8% per quarter. A fresh Truelist check catches any contacts that churned since SalesIntel's last review.

Does SalesIntel's human verification guarantee deliverability?

Human researchers confirm that an email is associated with the right person, but they cannot guarantee the mailbox is still active. SMTP verification confirms the technical deliverability.

Can I verify only high-intent contacts?

Yes. Export a filtered list of high-intent contacts from SalesIntel and verify just those with Truelist, so your most time-sensitive outreach goes to confirmed addresses.

Free SalesIntel Email List Verifier

SalesIntel is a B2B data provider that combines human-verified contact data with intent signals and firmographics to fuel sales and marketing teams.

Why verify your SalesIntel email list

SalesIntel uses human researchers to verify its data on a 90-day cycle, but contacts can change jobs between verification windows. A human-verified email from 60 days ago may already be invalid if the contact switched companies. Real-time SMTP verification fills the gap between SalesIntel's periodic checks and your actual send date.

check Bridge the Verification Gap: SalesIntel re-verifies on 90-day cycles. Truelist checks deliverability right before you send, catching recent changes.
shield Protect Campaign Performance: Even human-verified data ages. A fresh verification ensures your campaign hits live inboxes, not abandoned mailboxes.
analytics Maximize Intent Data Value: SalesIntel's intent signals identify buyers in-market. Verified emails ensure you can reach them while the intent is still hot.
savings Reduce Wasted Outreach: Every email sent to an invalid address costs money in sending tools, sequence slots, and rep time. Verification eliminates this waste.
