Not a trial, not a feature-limited tier, and not a card you have to remember to cancel. Every capability below is on for every workspace, because billing is not built yet and there is nothing to divide.
Written from the code rather than from a plan document. If something is listed here it is running in production right now.
Paid plans are the one genuinely open question here, and the honest answer is that the prices and the tier boundaries have not been chosen. Payment processing is not wired up, so there is no upgrade button to hide behind a “coming soon” badge.
What that means in practice: pacing today is governed by your mailbox caps, the sending window and the warmup ramp, all of which you control, rather than by a plan limit. When plans do land, the send limits will be part of them. Until then this page would rather be short than invent a table.
Which makes this the easy part: create a workspace and every capability above is already on. Nothing to compare, nothing to downgrade from later.
