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.

There's an option for buying prepaid credits in case we can't pay for the monthly subscription for a while.

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.

This used to a very tedious and time consuming process that I did manually. With virtually no troubleshooting and very easy configuration, I have literally saved myself hours of work every single week, and it even does a better job than I did before on my own. When I have questions or issues come up, it is very easy to reach out and get quick help. Most of all, I appreciate not having to think about email deliverability and just focus on the emails I'm sending.

I really appreciated how easy it was to deploy and how effective it really is at flossing our database. It's also very accurate now and it's constantly improving based on feedback!

Occasionally there's glitches that need to get fixed, and its accuracy is really great but not perfect (though I think that's unattainable for email deliverability anyway).

Very positive experience! Mailfloss provided easy instructions to integrate with my email service provider to clean my contacts, and cleaning went off without a hitch. When I had questions, [SENSITIVE CONTENT HIDDEN] was quick to respond. He was very helpful through the whole process. Excellent customer service!

Mailfloss was easy to set up and integrate with my email service provider. Just a few clicks and then I could let it run in the background and forget about it. I especially like how Mailfloss breaks down what it catches by what contacts have full inboxes, are duplicates, are fake, misspelled, etc.

The after-cleaning reports can be confusing. It takes some digging to figure out exactly how many contacts passed a cleaning and how many were blacklisted. This could probably be remedied with a simpler UI. Allowing free trial users to clean more than 500 contacts (like 1k) would be great too.

I'm using Mailfloss in a high-growth email program at scale and would highly recommend it as an automated solution for keeping your email database clean.

Lower cost than other alternatives I considered with more customizable features. Mailfloss has found the one thing they can do well, and they do it very well. My integration is with Hubspot and I appreciated the custom properties for list segment and suppression control, the automated list cleaning, and the consistent release of new, valuable features like typo fix.

Mailfloss was a newer software tool on the market, so it was a little untested, but I was excited to give it a try and it has delivered on expectations.

I've been very happy with Mailfloss. Its functionality, ease-of-use and pricing are all terrific.

Mailfloss has great Infusionsoft integration, with flexible options including unsubscribing and/or tagging bad contacts, and daily cleaning of new contacts. No 3rd party service like Zapier required.

It would be great if there was some alerting mechanism if the number of cleaned contacts changed substantially week-to-week.
