Thanks for the detail here, it helps us answer properly.

Verification confirms that an address exists and accepts mail at the moment it's checked. It's a point-in-time result, not a permanent guarantee, and there are a couple of well-known reasons a confirmed address can still bounce later.

The first is a gap between checking and sending. Addresses go dead as people abandon them, and forum lists in particular tend to age, so an address that was live when we checked it can stop existing by the time you send.

The second is receiving servers that accept at check time and bounce later. Some servers confirm an address during the SMTP check, then reject the actual message for reputation or filtering reasons, and the bounce text can read as "address doesn't exist" even when that isn't the real cause.

It's also worth knowing we don't mark uncertain addresses as valid. Catch-all and accept-all domains, where the server confirms everything, are flagged unknown rather than valid, specifically so they stay out of your good list.

The fair way to settle this is the data itself. Send us the bounced addresses and we'll show you exactly what each destination server returns when we check them. We recently followed up through Trustpilot's request-for-information button to do this and didn't hear back, but the offer is open any time at support@bulkemailchecker.com.

Thanks for laying this out. This was our payment fraud review, and it's worth explaining how it actually works.

Every payment we take runs through a third-party payment processor that screens each transaction for fraud. We don't make that call ourselves and we can't override it. A large first purchase from a brand-new account is one of the most common triggers, because it's also the exact pattern of a stolen card, so the screen flags it to protect both us and the real cardholder.

Sending a matching ID is one signal we can submit to try to clear the flag, but it isn't a master key. The processor weighs a range of risk factors, and if it won't clear the transaction, we're unable to accept the payment at all. When we can't accept the payment, we can't provide the service, and you shouldn't be left paying for something you never received. If a charge actually went through, support can confirm and refund it.

On the data worry: because the account never became active, no list was ever processed.

This review is from 2019. If you're still owed a refund or want us to look at what happened, email support@bulkemailchecker.com. We also followed up through Trustpilot's request-for-information button and didn't hear back.

Thanks for the feedback. A 50,000 list taking a week long to process is definitely unexpected. Also, it's worth explaining what drives our time estimate and actual final processing times.

Processing speed depends on how quickly each destination mail server responds, and that varies a lot from list to list. The time estimate is based on average response times, so a list weighted toward slow or rate-limiting mail servers can run well past the estimate. That's the kind of thing we'd want to look at on your specific job.

On support: we're a cloud-based, self-serve platform, so we don't maintain a phone support line. Everything goes through our ticket system, which usually responds within a few hours on business days. If you saw a phone number on a receipt, it was not a staffed support line.

On the speed boost: standard processing always completes on its own at no extra cost. The faster option is optional and never required to finish a job.

If you want us to look at what slowed that list, reach us at support@bulkemailchecker.com. We also followed up through Trustpilot's request-for-information button and didn't hear back.
