We enjoy having amazing clean email data every day and a fantastic sender reputation. No blacklists, all time low email bounce rate. We have tried other email verifiers. But nothing comes close to mailfloss.

This used to be a very tedious and time consuming process that I did manually. With no troubleshooting and very easy configuration, I have literally saved myself hours of work every single week.

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.

In short

How much does it cost to verify 10,000 emails?

On mailfloss, 10,000 credits a month is the Lite plan at $29/month, and a credit is one address verified. That buys continuous cleanup, not a single pass: your connected list is re-checked daily and decayed addresses are removed under your own rules. Typo Fixer starts on Business at $59/month for 25,000 credits. If you only need one cleanup, prepaid credits do it without a subscription and never expire.
