Two products. Each priced by what it actually uses.
Transactional email is priced by send volume. Marketing email is priced by audience size. Each is fully usable on its own — be free on one side and scale the other.
Transactional
Receipts, resets, alerts — priced by send volume alone.
3,000 sends every month, free — no card.
Then buy blocks of 25,000 sends. Rates drop as you grow; past your blocks it's just $0.4/1,000 — sending never stops.

Marketing
Campaigns, sequences & replies — priced by audience size.
Free up to 500 contacts — no card.
Your audience size sets the price; the plan turns it into monthly volume, a daily cap, and how many audiences you can run.

Add-ons — priced per one, no plan required
Take one whether or not you’re on a paid plan. Pick them at checkout (one bill) or buy them on their own — and buying more never re-bills what you already have.
Team seat
One more teammate who can sign in and work in rootmail.
$8/mo per seat
Workspace
One more workspace — a separate space per product or brand, each with its own sending, templates, and audiences.
$10/mo per workspace
Dedicated IP
A sending IP address only you send from, so your reputation is entirely your own (most senders share a warm pool — this isolates yours).
$30/mo per dedicated IP
Client sending domain
Send on behalf of a client from their own verified domain, with their reputation kept separate from yours and everyone else's (for agencies and platforms).
$2/mo per client domain
Contact pack
Room for 500 more contacts in your audiences without changing your plan — headroom when a signup wave hits. Raising your plan's contact size costs less per contact; this is the quick overflow valve.
$16/mo per pack of 500 contacts
Audience pack
Room for 5 more audiences (lists) without changing your plan — for when you want another segment, campaign list, or brand and you're at your plan's limit. Moving up a plan raises your audience allowance for less per audience; this is the quick add-a-few valve.
$12/mo per pack of 5 audiences
AI credits
100 more AI assistant actions per month — drafting, building, and diagnosing across both wings.
$5/mo per 100 credits/mo
Custom team roles
Define your own roles from the full permission set — decide exactly who can send, edit content, or touch billing.
$15/mo per custom roles
SAML SSO + SCIM
Sign in through Okta, Microsoft Entra, or Google Workspace; new teammates are provisioned on first login and leavers lose access automatically.
$40/mo per SSO + SCIM
Proof & compliance exports
Cryptographically signed, tamper-evident records of exactly what you sent, exportable over any date range.
$25/mo per proof exports
One bill. Never billed twice. Yearly = 2 months free.
Add-ons picked with a plan appear inside the same checkout. Changing plans carries everything you own over and credits your unused time automatically. Go past your transactional volume and sending never stops — overage is billed per 1,000, and the free tiers simply pause at their cap.
