Priced per plan, not per seat
Per-seat billing makes organisations ration email addresses. We would rather charge for the size of the plan and let you arrange it however you actually work.
Ruber is priced per plan, not per seat. Pro is €6.99 a month for 20 mailboxes and 5 domains, and adding somebody inside that limit does not move the bill.
Per-seat pricing is the default in this category and it has one honest justification — cost scales with usage — and one dishonest consequence, which is that it makes you ration addresses. Teams end up sharing logins to avoid a line item. Aliases get used where a mailbox belonged. The billing model quietly designs the mail setup, and it designs it badly.
We would rather charge for the shape of the thing
So the number that moves the price is the size of the plan, and inside a plan you can arrange mailboxes however the organisation actually works. A role address for every function costs nothing extra. Giving the new starter their own mailbox on day one is not a purchasing decision.
What we do count
Outgoing volume, per day, across the whole plan rather than per mailbox. Not because sending is precious, but because sustained automated sending is a different product with different infrastructure behind it, and a mailbox is the wrong place to put it — for the sender's delivery as much as for everyone else's.
Ordinary correspondence never comes near these numbers. They are published on every tier so you can check that against what you actually do, rather than discovering the limit by hitting it.
And the trial is the whole product
30 days, no card, and a domain of your own from the first one — 5 mailboxes and 10 GB, which was the Personal plan for a month. Not a sample, and not a demo account: the thing you are deciding about.
When it ends, sending stops and nothing else does. The mail stays readable, stays exportable and still arrives. An expiry that locked you out of your own correspondence would make the decision for you, which is not a decision.
