Most teams already run a fleet before they find Mail Halo.

Google, Microsoft 365, Azure and SMTP inboxes in your workspace are each judged by their own provider’s rules from the first nightly scan. Domains you already own come in with a TXT proof.

  1. Connect the workspace

    Add your EmailBison workspace API key. Mail Halo reads the inboxes, campaigns and tags already there.

  2. Pick a sending profile

    Set the ramp curve and daily limits. Inboxes already ramping are retuned when you change the profile.

  3. Keep them healthy

    Every inbox is rescanned nightly and judged against your rules.

Everything you run today, in one fleet.
