Find what fits the way you work

Whatever you send, and whoever you send it to, here's how to check your email addresses first.

Agencies

Keep each client's lists separate, protect their domains, and share a report.

Clean your customer list yourself, with no developer and no subscription.

Upload a CSV, get every address back marked valid, invalid or risky. No code.

Export your audience, find the bad addresses, and remove them from Mailchimp.

Verify every prospect list before it hits the sequencer, so campaigns start clean.

Check purchased, scraped or enriched contacts before the first send.

Bulk verify your database quarterly so reps stop working dead addresses.

Catch bad addresses at checkout so confirmations, shipping updates and receipts actually arrive.

Verify candidate lists before outreach — response rates that reflect your message, not your data.

Block disposable and undeliverable addresses before they become rows in your users table.

One endpoint and one JSON response, integrated before lunch.

Connect the native MCP server and verification becomes a tool your agent can call mid-task.
