- Their pitch: Use the API to verify emails in your sign-up forms, apps, and scripts — one address at a time or in big batches.

## Data

- Freshness: live
- What it checks: format, mail servers, disposable domains, role addresses, mailbox
- Keep data: no limit
- Use data: Acceptable use: You will not use CleanMyList to enumerate email addresses you do not have a legitimate basis to verify, to harvest contacts, or to harass recipients. Verification requires a legitimate sender relationship — your own list, a customer list, or a list you are processing under a Data Processing Addendum. No bulk verification of scraped data without a clear lawful basis. No verification of lists for the purpose of credential stuffing or account takeover. No bypassing of our rate limits or sharing of API keys across organizations.
