Product / Bulk verification

Clean the list you already have

Turn a raw email file into a campaign-ready dataset.

Upload a CSV or plain-text list, choose the evidence depth, and let verification run in the background. Download a clean deliverable set plus a complete, enriched audit file.

  • CSV + TXT up to 10 MB
  • Background processing
  • Verified + all-results exports

A large list hides expensive mistakes

Do not discover bad addresses after the campaign launches.

Old exports, purchased data, merged CRMs, and event lists accumulate typos, dead domains, disposable accounts, role addresses, and unreachable mailboxes. One send can turn that debt into bounces and damaged trust.

01

Reduce avoidable bounce risk

Separate valid or deliverable records from invalid, risky, undeliverable, and unknown outcomes before they reach the send queue.

02

Preserve the data you started with

CSV exports keep every original input column in order, then append verification and enrichment fields.

03

Make list decisions explainable

Download the clean subset for action and the full result set for review, segmentation, or audit.

Made for bounded datasets

Use bulk verification before a list becomes an audience.

The workflow is designed for finite files that need one consistent verification policy.

Campaign preparation

Clean a marketing or outbound list before upload to your sending platform.

CRM migrations

Assess legacy contacts before moving them into a new source of truth or automation system.

Event and webinar lists

Check registrant exports before reminders, follow-ups, and sales handoffs begin.

Agency list hygiene

Process separate client files with visible job status and downloadable results.

Data enrichment pipelines

Preserve source columns while adding classification, role, person, provider, and verification fields.

Dormant-list reactivation

Reassess an older audience before risking sender reputation on stale addresses.

From file to usable audience

Upload once. Let the job run. Download the decision.

Large files move directly to secure object storage and process outside the browser.
