About mailfloss

Built by people who got tired of cleaning email lists.

mailfloss was created to solve our own email deliverability problem. We needed an email verification tool that wasn’t a pain to use. Nothing was out there — so we built one. Today it cleans 5,000+ teams’ lists on autopilot.

The story

mailfloss started with Martin (our founder) and a Google Sheet. Every week the same job: export the list, run it through a verifier, re-import the clean version, repeat. The job was important. The job was tedious. The job kept getting forgotten.

So we built the tool we wanted: one that connects directly to the email platform, runs in the background, and never needs to be remembered. Typo Fixer came first — a single feature that recovered subscribers other verifiers were silently deleting. Then Instafloss, then Autofloss, then Decay Protection. Each one named after the work it does.

Years later, we’re still small — a team you could fit at one table — and still focused on the same thing. mailfloss does email list hygiene so well that you stop thinking about it. That’s the whole product. Hand-crafted, in Canada.

“We never wanted to build a dashboard people stare at. We wanted to build the one they forget about.”
— Martin, founder

What we believe

Three principles. They’re also why the price is what it is.

Accurate, always

An email verifier is only useful if it’s right. mailfloss runs every address through 20+ checks on a global infrastructure. We’ve been iterating on accuracy since 2017.

Affordable, on purpose

Our prices are some of the lowest in the industry — and we keep them that way deliberately. We’re customer-funded, so there are no VCs to satisfy with growth-at-all-costs targets. Lower overhead means lower prices for you.

Automated by default

The best email-hygiene tool is the one you forget you have. mailfloss connects in 60 seconds and runs in the background — we measure success by how rarely you have to think about us.

By the numbers
