Shared inbox cost calculator

How much does a shared inbox or help desk really cost in 2026? Entry prices run from free to $79 a seat across the 43 tools here, and the sticker is rarely the bill: seat caps, per-outcome AI fees, and expiring credits move the real number. Set your team size and AI volume and this page computes the same month across every tool, from each vendor’s own published pricing. For comparison throughout: Drag, our shared inbox for Gmail, costs $12 to $24 a seat with AI included from $18 and nothing metered.

Frequently asked questions

How much does a shared inbox cost?

It depends on your team size and AI usage. Per-seat tools run roughly $10 to $79 a seat; Drag, our shared inbox for Gmail, costs $12 to $24 with AI included from $18. Per-workspace tools like Crisp charge by bundle ($45 to $295 a month), and per-outcome AI agents like Fin add $0.99 per resolved conversation. Use the calculator above to model your exact bill.

Which shared inbox is cheapest?

Tawk.to is free with minimal AI, and Google Groups is free if you only need a basic collaborative inbox. Among paid tools the answer depends on team size: per-workspace bundles like Crisp win at some sizes, per-seat tools at others. For Gmail shared inboxes with AI included, Drag runs $12 to $24 a seat. Set your numbers above for the real answer.

How does AI pricing work for support tools?

AI pricing varies by model: included in the seat (Drag, from $18), per-resolution (Help Scout $0.75, Fin $0.99), per-session (Freshdesk about $0.49), or credit-based (Crisp). Per-outcome pricing scales with volume, so a busy month raises the bill; seat-included pricing stays flat.
