## In their words

- Their pitch: Find a person's address from name + company, or every role mailbox at a domain — then verify it.

## Data

- Keep data: no limit
- Use data: You agree not to: Upload lists you don't have a lawful basis to process, or verify addresses to facilitate spam, phishing, or harassment. Use verification results to target addresses in violation of CAN-SPAM, GDPR, CASL, or other applicable marketing laws. Resell, sublicense, or white-label raw verification capacity without a written reseller agreement. Probe, scrape, overload, or reverse-engineer the Service, or circumvent rate limits, credit metering, or security controls. Acceptable Use Policy, you must not use the Service to: Harvest or scrape email addresses you have no right to contact, or process lists bought from data brokers known to be non-consensual. Send spam — unsolicited bulk email, or any message that violates CAN-SPAM, GDPR/ePrivacy, CASL, or similar laws. Enable harassment, fraud, or phishing, or build lists targeting individuals to threaten, dox, or deceive them. Verify lists for malware, scams, or illegal goods distribution. Abuse the infrastructure — circumvent rate limits, probe for vulnerabilities, share credentials, or resell raw access without a reseller agreement. Process special-category data as the primary payload (e.g. lists defined by health, religion, or political affiliation) without a clear lawful basis.
