Email verification questions, answered

What is email verification?

Email verification checks whether an email address can receive mail before you send to it. It tests the format, the domain, the mail server and, where possible, the mailbox itself, so you can remove invalid addresses and avoid bounces.

How does Mailbite verify an address without sending an email?

Mailbite checks the syntax, confirms the domain and its MX records, flags disposable providers and asks the recipient mail server whether the mailbox exists. The conversation stops before any message is sent, so the recipient never receives anything.

How much does email verification cost?

Monthly plans start at $19.90 a month for 25,000 verifications, and every account gets 100 free verifications each month. See the pricing page for all plans.

Is there a free plan?

Yes. Every account includes 100 free verifications per month, and you can check a single address on the home page without signing up.

Can I verify a whole list at once?

Yes. Upload your list file in the web app, watch results appear while it is processed, and download the cleaned results by status.

How long are my uploaded files kept?

Uploaded lists, result files and the bulk itself are deleted from your panel 14 days after they are created, so download your results within that time. Your credit usage stays in your account.

Is there an API?

Yes. An API for verifying addresses is available from the account area, for example to check addresses at sign-up.
