Pricing

Simple per-mailbox pricing.

Every tier is priced per active mailbox per month with a 25-mailbox minimum — $25 a month gets you started. There is no monthly floor beyond that and no service plan to buy alongside it.

Questions

Is there a minimum?: Yes — 25 mailboxes, on every tier. On Garnet that is $25 a month. A floor this low covers the fixed cost of running a tenant properly without pricing small organizations out; there is no $350-a-month minimum and no separate service plan.
What counts as a mailbox?: A mailbox that sent stamped mail during the month. Your first invoice is based on your own estimate; after that, billing follows observed use, and any increase is notified 30 days before it applies. Shared mailboxes and service accounts that never send through RubySig are not billed.
How do I pay?: By card or bank transfer, invoiced monthly. Crown accounts can be invoiced on their own terms.
Can I change tiers?: Any time. The new rate applies from the next invoice, and nothing about your setup changes — the connectors, rules and DNS records are the same on every tier.
What does support look like?: Email support from the people who built it, on every tier, usually within one business day. Ruby and Crown are answered first. We do not advertise 24/7 phone support, because we cannot staff it honestly.
How do I get started?: Request access. We approve your organization, issue your connection values, and one administrator connects your platform in about twenty minutes by following the setup guide.
