Free diagnosis
Paste one EmailBison workspace key and get a report on every inbox in it. Free, and no account needed.
Doctor
It checks every inbox and domain, explains what changed and why, and lines up the fixes for your approval.
Inbox rotation
Judge every inbox by your rules, rest the ones that slip, and bring them back when they recover. Sending volume follows evidence.
Auto-reserve & replenish
Keep warm reserve inboxes on standby, replace burned ones automatically if you switch it on, and keep domain stock topped up.
Launches
A report on each launch batch through its first 30 days of warmup, with a verdict per batch and when any blocklisting hit.
Deliverability tools
SPF, DKIM, DMARC, MX, BIMI, MTA-STS and TLS-RPT lookups, blocklist checks, an email verifier, and a full report you can share.
Build better inventory
Bring your own inboxes
Connect your EmailBison workspace and Mail Halo reads every inbox already in it. Nothing has to move.
Google inboxes
Order inboxes in five steps. Mail Halo creates the Workspace tenant, sets up DNS and two-step verification, and connects every inbox to EmailBison.
Pre-warmed inboxes
Every new inbox warms first, then ramps to its daily limit on a schedule. Warmup keeps running alongside cold sending.
Stealth domains
Buy brand-neutral sending domains on your own registrar account, at a steady daily pace, inside a budget you set. Keep client names out of sending domains.
Aged domains
Hold each new domain for an aging period before its inboxes go live, with a record of how it got there.
Landing Factory
Give each domain its own landing page on your Cloudflare account, with business details and a contact path.
