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

Horrible

Horrible. Payment has only worked once in two months. I know it's not my card b/c I'm using it for everything else, I've called my bank and they've said they're not getting an investigation, and I've asked MULTIPLE friends to try - all of which couldn't.

Customer support has been a nightmare. Doesn't even feel like they're there - like I'm talking to a ghost. I've contacted them about this on probably 10+ separate occasions and have been hit with the "we're actively investigating this problem" every single time. I'm trying to believe it's a human on the other side, but with how similar and unresponsive each message is, it really just seems like AI.

No number. Nothing to call. The single most infuriating service I've ever dealt with.

Sad part is, I WANT to buy the service. It's still the cheapest verification on the market. But I guess that's why they're customer support is laughably terrible.

Definitely Recommend

Fantastic tool! Easy to use, affordably priced, and very clean UI. Reports are clean and easy to manipulate into whatever format you need. Highly recommend.

Great Service but WORST performance in…

Great Service but WORST performance in the backend.

Frontpage is loading but backend is a CATASTRPOHY. Loading time multiple minutes. Files are lagging downloading with we kbs.

I use no VPN have a updated Mac, in Frankfurt Germany. Every other page is loading as well as 4k movies. So please fix that!

You'll probably all know these small errors over the day which make you look nerves and 100x the time that it used to be. Thank you MillionVerifier to be that for me.....

Responsive support team

Support was responsive when the bulk API was not working. Everything seems to be working correctly now. I've only been using the service for a few days, will update this review again when I can share more about the results and stability. Thank you!

Million Verifier is a MUST HAVE tool

Million Verifier is an excellent program I use to keep my email list fresh! The process is quick and delivers a report in 3-categories (good), (risky), and (bad). Download the email(s) you want to keep. The cost is very economical (insignificant really) for the peace of mind of having a list of real deliverable emails.
