About mailfloss

mailfloss is a cloud-based solution that helps businesses of all sizes automatically scan and remove invalid and fake email addresses from email lists. It offers a decay protection module, which enables employees to prevent outdated email addresses, ensuring protection of domain reputation.

Features of mailfloss include syntax check, disposable email detection, tagging, reporting, mail server validation, single email verification, spam detection and more. The platform lets sales and marketing teams add various keywords in the blacklist segment to avoid inclusion in emails. Additionally, administrators can use the platform to automate workflows by setting verification preferences to unsubscribe or delete email addresses.

mailfloss provides an application programming interface (API) and Zapier integration, which lets businesses connect with several third-party platforms such as MailChimp, Constant Contact, Ontraport, Campaign Monitor, HubSpot and more. Pricing is available on monthly subscriptions and support is extended via phone, email and other online measures.

Pros:

Easy to setup. I like how email checking is put on autopilot after the initial setup.

Cons:

It's simple but there a lot of additional options, as well, that can be intimidating. Luckily there are lots of tooltips and their help widget has tutorials and video walk-thrus.

Thank you, Chris! I really appreciate your review.

Pros:

Took me a day to compare different providers, and about 10 minutes to test out Mailfloss with the free trial. Started the paid package next day, and its functioning well so far! Direct integration with our (several) ESP, and daily cleaning for 17€, pretty decent. The CS responds nearly immediately.

Cons:

Not too much to mention here, will circle again in a few months

Thanks, Tanya! Happy to read that you chose us so quickly after comparing providers and using our free trial. Appreciate it! - Martin

Auto-mazing software to keep your email marketing data sparkling clean

We enjoy having amazing clean email data every day. This means our email sending CRM has a fantastic email marketing reputation. No blacklists, all time low email bounce rate. Super High email deliverability, opens and clicks... and Earnings Per Click. We have tried other email verification services. But nothing has come close to MailFloss.

Functionality

Pros:

MailFloss is producing accurate results and is super easy to both set up and maintain. In fact unless we have to manually import a new list of prospects into our CRM from a third party everything is fully automated and emails me a confirmation message every day. Its stress free. :-)

Cons:

Like all new software, you need to give it the time to learn how to use it. It took perhaps 1-2 hours. The pain was well worth the reward later.

Reasons for choosing mailfloss

it was a false economy to go with anyone else. When you have found the right product, at the right price, that has the right customer service... what else could you possibly be still looking for? MailFloss ticked all the right boxes then... and it still does almost 12 months on. We've VERY happy.

Reasons for switching to mailfloss

the ease of the AutoFloss Automation with our CRM... and the amazing customer support.

Vendor Response

Awesome, Nick! I really appreciate your support and I'm glad everything is stress-free for you. That's exactly what we're going for. Martin

Works Seemlessly In The Background

Very Good. Response time when I have questions is fast and effective, which is always a good thing. It gives me a good feeling that the product is well supported and that customers are appreciated.

Functionality

Pros:

Once I configure the features, the app works seemlessly in the back ground to keep my email list nice and clean.

Cons:

Unless I missed it, it would be nice to have a preview button to see a list of emails that would get scrubbed/deleted before I actually commit to saying yes. I say this because I initially configured some setting too aggressively and ended up getting rid of some good subscribers that I recognized.

Vendor Response

Thanks, Doug! I'm really happy to read your review and to hear you are happy with the service. Apologies about the "preview". It's the first option "Manually decide action on invalid emails" but I think at the time you set up your account it wasn't so clear. We've since added tooltips and more documentation to make it more clear. With this option set you first review the emails and decide if you'd like to delete or unsubscribe or ignore them. This is generally a good idea at the beginning until you're comfortable with our results before turning on an auto action, such as auto-unsubscribe. Thanks again for the lovely review!

Can't say enough good things about mailfloss!

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!

Pros:

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.

Cons:

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

Vendor Response

Hey Christopher, I'm so happy to read this, what a way to start the day :) Thank you, I'm glad you like our Infusionsoft integration. We work really hard on them to ensure they are top of the class. We've got something special for our Infusionsoft integration soon so stay tuned. And cool idea about the alerting mechanism, I've added it to our feedback and ideas boards.

Customer service is King.

Excellent. Super responsive, helpful, professional company. Whatever you need there the to help. Not 48 hours later. You're not getting an automated response and a generic answer 3 days later. You're getting an extremely helpfull person right away ready to help you even if it's just to help you understanding something.

Pros:

Ease of use - we use manual cleaning for now and it's easy to upload files and get results. We love the way the results are stored and the ranking that mailfloss gives the email.

Cons:

The speed - it would be epic if you could make it faster! Drag and drop uploading files would be ideal. The rankings of the emails could be simpler.

Vendor Response

Thanks so much for the kind review, Alexander. I'm happy to hear we're helping you where other email verification services miss the mark. We hear you on the speed, it's something we're constantly improving without compromising quality. We've also made a ton of tweaks and UI improvements lately based on user feedback including a more intuitive dashboard and drag and drop file uploading. I have a huge smile on my face reading that we save you both time and money - what a combo! :)
