Switch clients,
not contexts.
A workspace switcher in the dashboard plus a hotkey. Each workspace owns its keys, domains, suppression list, billing, and people. Nothing leaks across the wall.
Isolated per workspace
Keys, domains, logs, suppression — all scoped. Audit logs prove the wall.
Hotkey switch
⌘ ⇧ W from anywhere in the dashboard. No round-trips through a settings page.
Cross-workspace search
Find an email by recipient across every workspace you have access to (admins only).
Invite without leaking
Invite a client to their workspace; they can't see anything else.

Their domain,
their reputation.
Every client sends from their own sub-domain — DKIM signed by their key, DMARC reports route to their inbox. Pro Max gets per-client dedicated IPs.
Per-client DKIM keys
Each domain gets its own DKIM selector. Reputations never bleed.
Per-client DMARC routing
Aggregate reports forwarded to the client's configured RUA/RUF.
Custom click-tracking domain
links.<client>.com so open + click URLs wear their brand, not yours.
Co-branded dashboard
Logo + accent color per workspace on Pro Max. Or hand the dashboard to the client wholesale.

Bill them,
bill us, or both.
Three modes: (1) you pay, mark up, invoice the client. (2) Client pays direct, you keep dashboard access. (3) Hybrid — we split the invoice and you each get a line item.
Per-workspace invoices
Client gets their own invoice from VoltMail; you stay outside the billing relationship.
Markup mode
You pay us, we expose a line-item to the client. Markup % visible only to you.
Volume rollup
Aggregate sends across all client workspaces toward your contract — bigger discount tier.
Tax-inclusive lines
Per-region tax handled. Stripe Tax wired in.
