While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Solid verifier. Only thing that's missing is an Affiliate program. Not super chuffed that they do not have one. As 90%+ SaaS companies have them and it helped us refer people. These guys want us to pr... See more

I use MillionVerifier to clean my prospecting lists before running cold email campaigns, and it's been reliable. I verify business emails I've collected and it accurately flags the good, risky, and bad ones so I only send to addresses that will actually land. The bulk credits are priced well — much cheaper than a lot of the competitors I looked at — and the credits don't expire, which is great since I verify in batches rather than all at once. The API is straightforward to work with too, so I could automate my verification instead of manually uploading files every time. Accuracy has been strong and I haven't had bounce problems on the addresses it marks as good. Recommended if you need to keep your lists clean.

MillionVerifier cut our bounce rate to a fraction of what it was. We use the popular (and expensive) B2B email finders, and the lists still come back with far too much bad data — which was quietly damaging our overall deliverability. MillionVerifier catches what they miss. Fast, cheap, and it paid for itself immediately in sender reputation alone.

Used you for a few weeks a year or two back. Million Verifier is one of 7 things that we do. All connected to the 23 year e-marketing grand plan. If we knew then what we know now? Yeah, except the technology was nil in that day of the week. Thanks.
