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. Lite covers continuous cleanup rather than a single pass: it cleans your connected list daily, removes addresses that decay over time, applies your own keep and remove rules, and includes the real-time API. Typo Fixer, webhooks, and real-time bounce prevention start on Business at $59/month for 25,000 credits — worth checking against the plan table above before you compare on price alone.

Compare it on what you actually spend in a year, not the sticker price of one bulk run. A one-off verifier charges you again every time the list needs checking, and a list decays continuously, so the honest comparison for a recurring sender is one bulk run per quarter against a subscription that never stops running. If you genuinely only need a single cleanup, prepaid credits do that without a subscription and they never expire.

Questions

Frequently asked.

Yes — every subscription plan starts with a 7-day free trial. Subscription plans require a supported email service provider; if yours isn’t supported, buy prepaid credits instead.

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 mailfloss cost?

mailfloss is priced by how many contacts you verify, not by seats. Subscriptions run automated cleanup continuously across your connected email platform, while prepaid credits cover one-off bulk CSV checks with no subscription. A free trial lets you clean your list before you pay, and plans scale up as your list grows — so you only pay for the verification volume you actually use.
