Email address validation for everyone. Stop wasting money on typos.

Your email list is precious. Make sure it’s clean and protected against invalid emails automatically with mailfloss

Fake emails suck. They’re a financial drain, lost opportunity, and hurt inbox deliverability

An invalid email means there isn’t a real person on the other end. This sucks on so many levels. First, there’s the cost of sending the email. Second, there’s the cost of storing the email in your email service provider. Then there’s the fact that sending too many invalid emails results in lower inbox deliverability. That means the emails you send become less effective because they aren’t reaching the real people on your list. That’s less profit and higher costs for no good reason. Not cool. But fear not, mailfloss has you covered. Accurate, fast, daily automated cleanup, and really easy to use.

You’re busy, we get it. Email verification shouldn’t be so hard.

With mailfloss, it’s easy. 60 second, one-time setup. No developers needed. All you need is a supported email service provider. With one of those, press a few buttons, pick your preferences, and voila, you’re all done. From that point on mailfloss will keep your email lists squeaky clean. It’s simple, but crazy powerful.

Fully automated with the most popular email providers

Our integrations are the best in the business, bar none. Not only do they automatically clean your email lists, they do this daily, without developers, and allow you to manually or automatically delete or unsubscribe invalid emails. Our integrations are only getting better. For example, many of our integrations have the ability to tag or update custom fields for failed contacts, as well as whitelist subscribers who contain certain tags and/or custom fields. This is advanced level configuration and not necessary if you don’t need it. It’s all completely optional and up to you.
