Email verification that runs on autopilot
mailfloss helps busy businesses verify email addresses, remove invalid contacts, fix common typos, and keep lists cleaner without recurring spreadsheet work or developer-heavy setup.
Why teams use mailfloss
Set up mailfloss once, choose your cleanup preferences, and keep email list hygiene running around the tools you already use.
What is email verification?
Email verification checks whether an email address is valid, reachable, risky, disposable, typoed, or likely to bounce. It helps businesses reduce bad addresses before they waste sends, distort reporting, or hurt deliverability.
- Verify new contacts before they become a bounce problem.
- Clean existing lists on a recurring schedule.
- Fix common email typos and sync changes with supported ESPs.
Fake and invalid emails are a quiet revenue leak
Bad addresses cost money to store and send to, create avoidable bounces, pollute reporting, and can make campaigns less effective for the real people on your list.
mailfloss keeps list hygiene simple: connect your email platform, set your rules, and let automated verification reduce the bad-address work that normally comes back every month.
- Remove, unsubscribe, tag, or review invalid addresses based on your preferences.
- Catch bad contacts as they enter your email platform.
- Clean older contacts so list decay does not quietly compound.
- Protect campaign performance with cleaner email data.

Manual list cleaning vs automated verification
“mailfloss is literally the only piece of software that I use every single month that I do not even have to think about and I love that, because it is totally set and forget it.”
