Mailmo Review

Mailmo is an email finding and verification tool for B2B prospecting. It locates verified business email addresses and checks deliverability instantly, with catch-all verification included — a notable inclusion, since catch-all domains are where most email finders return risky, unverifiable addresses that inflate bounce rates. A Chrome extension surfaces emails directly from LinkedIn profiles, which is where most B2B prospecting starts, and the focus on verified addresses helps reduce bounces that damage domain reputation. A free monthly allowance of verified emails is available, and paid plans start at $9 per user per month, with Professional at $39 and a high-volume tier at $349 for teams.

Who It's For

Mailmo is aimed at sales, marketing, recruiting, and business development professionals who need accurate contact data before launching outreach. It particularly suits teams that have been burned by bounce rates from unverified email finders, since catch-all verification addresses the hardest category of addresses to validate. The low entry price and free monthly credits make it easy to test against your current data provider.
