Thanks for the feedback, and we'd like to clear this up, because the result you saw is the service working, not failing.
When you scrape contact emails off public e-shop pages, a higher than normal invalid rate is expected. Those pages are full of outdated addresses, role accounts, typos, and spam traps, so finding that half don't pass is exactly what a verifier is supposed to catch. The whole point is to flag the bad ones before you send, so you protect your sender reputation and don't burn sends on addresses that would bounce.
Here's what matters most: our system never guesses. For every address it connects to the destination mail server, and valid and invalid are both confirmed by that server directly. When the server won't give a clear answer, like a catch-all domain, we mark the address unknown instead of guessing. So the half that came back invalid weren't our estimate. They were the receiving servers rejecting those addresses. A verifier can't make a bad address good. It can only tell you which ones are real, and that is what it did.
We also followed up through Trustpilot's request-for-information button to walk you through your results, and didn't hear back. The offer still stands: send your job details to [email protected] and we'll go through the results with you line by line.
