We have an existing thirty- or forty-thousand addresses that we'd like to have cleaned up and then verify any new ones as we receive them. How can we do this with the API?
Cleanse your existing addresses.
Cleanse any new, incoming addresses. Use the API at your system's point-of-entry to capture addresses as they come in. This way you can save the valid addresses without ever having to worry about invalid data in your organization.
If you have further questions, we can probably help. Feel free to contact us about which product will meet your needs the best.
