Here's a walkthrough of the service. After submitting your addresses, Respect begins verifying them. You have access to a page with progress updates:

Once verification has completed, results (i.e. invalid addresses that Respect found) are made available. (If you submitted less than 50,000 addresses under our standard pricing, then these are all made available without charge.)

Results are available in both a summary report (partially pictured below) as well as a CSV or Excel export.

At any time, you may permanently delete the job data. Respect is left with no record of which names or addresses you submitted.
