Our take
Pick Shortwave if people who will reconnect Gmail and pay $30/seat after the trial. Pick Spark Mail if teams who will stay on Free while they clear a first Focused Inbox — then Plus at US$10/user/mo (or US$99/yr) when they want Gatekeeper / extra productivity, not Missive Starter $14 first unless they want a shared inbox as the default, and not if they need PGP (that’s Canary’s Pro+ desk).
