Allegrow
B2B email verification and placement monitoring for teams working with catch-all and gateway-protected domains.
Allegrow validates addresses that other tools return as unknown, including catch-all domains and mailboxes behind secure email gateways such as Proofpoint and Mimecast. It flags spam traps, disposable addresses, and dead inboxes, and distinguishes primary mailboxes from aliases. The product also monitors email placement and domain health, with an API and integrations for Outreach, Salesloft, and HubSpot.
