MX Check Hub

Email address verification & deliverability checking

Service operational

What this service does

MX Check Hub is a private email-verification service. It performs DNS / MX record lookups and standard SMTP mailbox checks to confirm whether an email address is able to receive mail. This keeps contact lists accurate and reduces the number of messages that would otherwise bounce.

How it is used

Validating our own business contact lists before manual outreach.
Removing dead or mistyped addresses so we never send to invalid mailboxes.
Low-volume, non-marketing verification requests only.

This is not a bulk-email or marketing-mail sending platform.
