Keep your list clean inside the platform you already use.
Connect any of 40 email platforms in one click. mailfloss then removes the addresses that bounce, drag down your sender score, and quietly inflate your bill — automatically, every day, right where your contacts already live.
A real integration — not a CSV round-trip.
Most verifiers make you export your list, run a check, then re-import the survivors — every single time. Miss a round and the dead addresses pile back up, your bounce rate climbs, and your campaigns start landing in spam. mailfloss connects straight into your platform and does the work where your contacts already live, so the cleanup just keeps happening without you.
Authorize over OAuth from your dashboard — no API keys to copy, no developer, no Zapier in the middle. Disconnect anytime.
Removals, tags, and typo fixes are written straight back to your platform. Nothing to re-upload, nothing to reconcile.
New signups are verified the moment they arrive; your existing list is re-checked on a schedule. Set it once per platform.
Delete invalids on one platform, tag them on another, keep Typo Fixer on exactly where you want it. Every connection has its own settings.
Common questions.
What's the Typo Fixer worth to you?
When [email protected] signs up, other verifiers mark it invalid and delete it. mailfloss fixes the typo and keeps the customer you already paid to acquire.
