## Data

- Use data: You keep all rights to the data you submit and to the results we return to you. You may only submit email addresses that you have the right to process. [...] You must not use the service: to verify addresses you have harvested, scraped, purchased without a lawful basis, or otherwise have no right to process, to build or clean lists for unsolicited bulk email or any activity that breaches anti-spam law, to probe, overload or interfere with the service, to circumvent rate limits or the free tier, or to resell the service without our written agreement, in a way that damages the reputation of our verification infrastructure with mail providers.
