Contact Verification.

Upload your contact list. Get back verified, corrected data - at scale, in seconds per contact.

What gets verified

Every field that matters. Checked and corrected.

Filto doesn't just flag bad data - it returns corrected data. Each field in a contact record is independently verified and updated where inaccurate.

Email Address

Verified for deliverability and accuracy. Invalid or bouncing emails are flagged and corrected where possible.

Job Title

Checked against current role. Outdated titles are replaced with the contact's actual current position.

Company

Confirmed against the contact's current employer. Stale or incorrect company associations are corrected.

Location

City and country verified against the contact's current location - not where they worked two years ago.

How it works

Our sources

We verify against every source that matters.

We don't publish the list - that's by design. What we can tell you is that it works.

Filto cross-references each contact across a proprietary network of sources. The combination of breadth, recency, and human oversight is what makes the difference - not any single source.

Our sources are our trade secret. Our accuracy is our proof.
