What every integration does

The core flow is the same regardless of platform: connect your account (OAuth or API key, depending on the platform), pick the list or audience you want to verify, kick off the task, and we return results. Each integration offers either Verify Only (results returned, your data untouched) or Clean List Automatically (results returned and applied back to the source platform — exact actions configurable per email type, see HubSpot for an example).

How to connect one

1. Open the dashboard and click Integrations in the sidebar (or use Bulk Upload → Connect Email Platform).
2. Find the platform you use and click Connect.
3. Authenticate — OAuth redirect for platforms that support it, or paste an API key for the rest.
4. Optionally name the connection (useful if you connect multiple accounts of the same platform).
5. Pick a list or audience from your connected platform.
6. Start a one-time verification or configure the automatic cleanup behavior.

Multiple accounts of the same platform

Most integrations support connecting multiple accounts. Useful for agencies managing several clients on the same ESP, or businesses with separate HubSpot portals per region or product line. Each connection appears separately in your Integrations page with the name you gave it.

What if your platform is not on the list?

Two options. First, use bulk verification — export a CSV from your platform, upload to us, download the cleaned file, re-import. Tedious for daily use, fine for occasional cleanups. Second, our REST API (which unlocks after your first credit purchase). If you have a developer or are one, the API gives you complete flexibility to wire verification into any platform that has an API of its own.
