I · The arithmetic of multiple domains
Workspace bills per user, so yes — you can park every domain on a single $7 seat as secondary domains. That path is real, and if it works for you, take it. What it costs is separation: one inbox identity, one sending reputation, and DKIM you configure by hand per domain. Break the entities apart to get that back and the bill becomes one seat per entity, which is the path the table below prices. Folio's answer is the third one — $2.99/month covers three domains with their own DKIM keys and one inbox to read them in, which is less than the single seat you were about to compromise on.
| 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.
