I · The arithmetic of multiple domains
If you run your businesses on Workspace, you can host every domain on one seat as secondary domains — but they share one inbox identity and one sending reputation. Many operators instead keep each entity in its own tenant for clean separation, and that's where the bill becomes one seat per entity. The table below shows that path.
| Domains | Workspace, a tenant each | Best-fit Folio annual | You keep |
|---|---|---|---|
| 1 | $7.00 | $2.99 | $4.01 |
| 3 | $21.00 | $2.99 | $18.01 |
| 5 | $35.00 | $12.00 | $23.00 |
| 10 | $70.00 | $12.00 | $58.00 |

II · Included with every plan
Every name you own arrives in one inbox — stable colour per domain, From auto-selected on reply. Paid plans price per operator, not per seat — Solo covers 3 domains, Studio 10, and Holding Co. lifts the cap entirely.
Per-domain DKIM, signed at send time with that domain's own key. Recipients verify the signature that belongs to the name on the envelope.
A one-time link to the address you already check. No password to remember, no password to leak. Single-use, fifteen-minute lifespan.
Letters moved to trash stay recoverable for a month. Attachments up to 15 MiB. Threading preserved on reply so Gmail and Outlook fold them into the original.
Dead addresses are marked before a second letter goes out. Your sender reputation doesn't drift because a contact's mailbox shut down six months ago.
Annual customers get one Stripe invoice at renewal. Bookkeeping is a single line item, not twelve.
Open the first letter
First 100 sends and one domain are free with no card. The 14-day card-required trial begins when you choose a plan to lift those caps; cancel inside the trial from the Stripe portal and nothing is billed. Questions about the price itself belong in the FAQ.
