Mail Halo

Find out which of your Bison inboxes are working

Connect your Bison workspace and we'll tell you which inboxes are working, which need replacing, and how your last 7, 30 and 60 days compare. Free, no account needed.

We save your report under this address so we can follow up on it.

Copy it from your browser's address bar in Bison. Just the domain is fine; we ignore https:// and anything after it.

Bison has no read-only key, so this one can send and delete mail on your behalf. We use it once, to generate this report, and never store it.

Where do I find this?

In Bison, open Settings, then Developer API, and create a key. Use a workspace key; agency keys are refused.
