The closest product in shape, and the one Missive publishes a dedicated migration guide for. Front charges $0.05 per conversation on top of the seat; Missive meters nothing and starts at $14 per user per month billed yearly.
Same shared-inbox buyer at a higher entry price, and it bills $0.75 per AI resolution where Missive expects a bring-your-own-key setup. Help Scout also documents no export path for its workflows; Missive exports rules as CSV.
Shared inbox with a help centre attached, which Missive does not have. Helply, formerly Groove, drops per-user pricing for $1 per ticket, so a small team with heavy volume can pay more than it would on seats.
Runs the shared inbox inside Gmail rather than as a separate client. A different working surface rather than a like-for-like replacement.
