Importing Dirty Lists Kills Deliverability

You bought a list of 50,000 emails, but half are invalid. Importing them raw destroys your sender score. Beton validates every email via MillionVerifier before it touches your CRM.

Risky List Buys

Purchased lists are notoriously dirty, but you have no easy way to clean them at scale.

Manual Verification

Uploading CSVs to verification tools and re-downloading results is tedious.

Partial Imports

You import the whole list, hoping for the best, and pay the price with high bounce rates.

Why Use MillionVerifier with Beton

Beton handles the entire workflow. Upload your list, let Beton send it to MillionVerifier, and sync only the 'Deliverable' emails to your destination—zero manual steps.

Beton is an open-source Clay.com alternative that orchestrates 100+ enrichment providers in one flow, including MillionVerifier.

Instead of wiring MillionVerifier directly into dozens of forms and scripts, you plug it into Beton once, define rules, fallbacks, and mapping, and send clean data into your CRM or warehouse.

Run Beton in the cloud or self-host it as a Docker container under MIT license, keep your MillionVerifier usage compliant, and avoid vendor lock-in.

How Clearbit works with Beton

Lead enrichment with Clearbit using Beton

Clearbit is great at turning anonymous signups into rich profiles—but wiring it directly into every form and tool quickly creates duplicated logic and hard‑to‑debug automations. Beton centralises Clearbit usage so you can define enrichment once and reuse it everywhere.
