Mailmo

What is Mailmo

Mailmo helps professionals locate and verify B2B email addresses in real time. It uses proprietary algorithms to check catch-all domains and reduce bounce rates. The tool fits into existing go-to-market stacks as a focused data enrichment layer.

Overview

Mailmo is an email finder and verifier built for B2B prospecting workflows. It locates contact email addresses and validates them instantly, including catch-all domains that most verifiers flag as uncertain. A Chrome extension lets users pull verified emails straight from LinkedIn profiles without switching tabs. The platform processes requests in real time, so there is no waiting for batch jobs to complete. Teams can export results as CSV files for import into CRM or outreach tools. Mailmo does not send emails or replace a CRM. It sits upstream, making sure the addresses that enter those systems are accurate and safe to reach.

How to use Mailmo

Create an account and install the Chrome extension. Navigate to a LinkedIn profile and click the extension to reveal and verify the contact email. For larger lists, upload a CSV to run bulk verification, then export the cleaned results into your outreach or CRM platform.
