inbox.help

Welcome to inbox.help, a set of tools to clean up your mail list and reach the inbox.

Domain validator

This tool lets you upload a list of domains, or a list of email addresses, and we extract the domains from them. We then check if the domains have MX-records published, if they don't have MX-records, we can guaranee that they don't recieve emails, and you should add these domains to your blocklist.
