Why mailfloss? So you can focus on your marketing, instead of worrying about valid emails

If you aren’t doing any sort of list hygiene for your email lists, you should be. It is one of the single best ways to improve your email deliverability, which means more ROI for your email marketing.

The problem with list hygiene is that it is a slow, manual, painful process that most marketers don’t enjoy. That’s where mailfloss comes in - we take out the manual processing and removal of bad and invalid emails. Your email lists never go sour with mailfloss.

The bottom line is the hard work is done for you. It’s totally hands off. No more remembering to upload your csv files and paying exorbitant fees.

What our customers are saying

Wow, mailfloss is impressive. Setup was dead simple – I was able to connect ConvertKit in less than a minute and mailfloss handled the rest. It processed over 150,000 emails without any issues, and now I can rest assured that my list going forward is going to be squeaky clean. I love the set it and forget it approach that mailfloss takes.
