The scrub time for a list of 100k seemed pretty long, but it's cheaper than ZeroBounce and very easy to use. Pros I liked how easy it was to set up with Iterable. Very clear demo videos made setup super simple. I think it took me maybe 3 minutes to get everything in place. Cons The only negative thing I could define was they didn't have live chat support. They have an AI chatbot which is pretty good, but otherwise you have to email their support team. Switched from [ZeroBounce](https://www.capterra.com/p/169340/ZeroBounce/) It was cheaper than ZeroBounce and easier to integrate Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

Recommend strongly" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 4.0 4.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 August 27, 2024 \[sensitive content hidden\] and his team were extremely responsive to requests, including some feature adjustments with real quick turnaround. Impressed! The solution works flawlessly and was a breath to set-up for our daily cleaning, and we were able to efficiently process our historical 100K email base in a few hours. Finally, cost is competitive with other solutions on the market. Pros Simple automation as well as full-on API access, intuitive interface and documentation, make for an easy set-up, autonomous for non-tech teams as well as more cpx technical integrations. Cons So far, none, running smoothly on our intercom integration since a few months, Alternatives considered [MailBoxValidator](https://www.capterra.com/p/152461/MailBoxValidator/) [Emailable](https://www.capterra.com/p/176754/Emailable/) Reasons for choosing mailfloss cost, ease of set-up and use, quality of validations Review source Incentivized review: software users are invited to submit an honest review and offered a nominal incentive for their time and effort.

Marketing Director Marketing and Advertising ### "Don't just clean your list - Floss it" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 4.0 4.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 September 27, 2023 It's an almost perfect solution for what it does and at this price point! We use it to clean up and review email lists from our clients to ensure they are safe to send - for us and for the client. So far so good! Pros quickly (depending on list size) verify and floss lists to weed out spam emails, invalid errors, and more. Customer service is super responsive. Highly affordable as well. We use the pay as you go version with credits. Cons There's no detection of malformatted emails in the credits only version. We don't use one of the major ESPs so it can't integrate with our systems. More features available in the monthly plans. Review source Incentivized review: software users are invited to submit an honest review and offered a nominal incentive for their time and effort.

Daily reports via email. Cons I first had to get used to the UI and the way things get setup. But after I wen trough the first integration the process became more intuitive and logic (I guess because by doing it the first time I then understood it;-)) Alternatives considered [NeverBounce](https://www.capterra.com/p/175437/NeverBounce/) Review source Incentivized review: software users are invited to submit an honest review and offered a nominal incentive for their time and effort.

AU Anonymous User Community Manager Arts and Crafts ### "Easy to setup and use" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 June 5, 2023 It's easy to use and there's a help page where I usually find answers if I have a question. I started using the manual mode to know better about how the service works and what to do with invalid addresses, and then got some help from the support team to set up an automatic option. Pros There's an option for buying prepaid credits in case we can't pay for the monthly subscription for a while. Cons I can't think about anything at the moment, since I've never experienced an error and I even think it has been getting better during my experience. There's a message every time they're experiencing a high amount of verifications so you can know that your process will take some time.

" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 July 12, 2022 Mailfloss hums along seamlessly in the background to keep our high-volume email database clean and tidy and deliverability woes at bay. The most remarkable thing about mailfloss, though, is that we've used it with 3-different high-powered email platforms and every time we migrate, their founder personally sees to it that the new integration is set up properly and we are in good shape for a massive contact transfer and extra flossing that comes with that. We are in such capable hands with mailfloss!
