Should you build or buy Shared Inbox?
Shared inbox software lets a team manage a common email address like support@ or sales@ together, with assignment, internal notes, and collision detection so two people do not reply to the same message. Small support and sales teams buy it to avoid stepping on each other in a shared mailbox.
If the team wants to stay inside Gmail, Hiver or Keeping remain the direct fit; if owning the support application and data matters, a self-hosted open-source helpdesk is a proven path. Building from scratch is not worth it; deploying an existing open-source product is.
Build it, buy it, or bridge?
When building makes sense
Standing up a self-hosted shared inbox is a realistic project rather than a stretch, because Chatwoot, an open-source, self-hosted customer support platform, has more than 25,000 GitHub stars, over 400 contributors, and SOC 2 Type II compliance for teams that care about that. It is explicitly positioned as an alternative to commercial helpdesk and inbox tools, and it covers the actual core of this category: shared address assignment, internal notes, and message ownership so two people do not answer the same email. Hosting it yourself means no per-seat licensing fee, and you keep the message data on infrastructure you control rather than a vendor's servers. What you give up is the vendor's Gmail-native workflow if that is how your team already works, plus the maintained mobile apps and integrations a commercial product ships out of the box. Building is worth it once someone on the team is comfortable owning that infrastructure and its updates.
When buying makes sense
Buying still makes sense for teams that want to stay inside Gmail's native interface rather than adopt a separate inbox application, the direct fit that Hiver or Keeping solve. Front runs $25 to $105 per seat a month depending on tier, and Missive runs $14 to $36 per seat a month billed yearly, both bundling mobile apps, automation, and maintained integrations a self-hosted deployment does not give you for free. The problem is that the core job, assignment, internal notes, collision detection, is genuinely a commodity, and Chatwoot's open-source platform, with more than 25,000 GitHub stars and SOC 2 Type II compliance, covers that same ground without a per-seat bill. Before renewing a large seat-based contract, price out what self-hosting an established open-source alternative would actually cost your team to run and maintain.

Frequently asked
Is a shared inbox subscription actually worth it for a small team?
It depends on how much you value staying inside your existing email workflow versus owning your data. Front and Missive bundle mobile apps and automation into their per-seat pricing, but the underlying job, assignment, notes, collision detection, is covered by Chatwoot, an open-source platform with over 25,000 GitHub stars, at no licensing cost if you are willing to self-host it.
What is the real difference between a shared inbox tool and a full helpdesk?
Mostly scope and integration depth. A shared inbox like Front or Missive focuses on collaborative email handling with Gmail-native workflows, while a broader helpdesk platform like Chatwoot adds live chat, ticketing, and multi-channel support on top of the same underlying assignment and collision-detection core.
How much does self-hosting an open-source shared inbox actually save?
Front's pricing runs $25 to $105 per seat a month and Missive's runs $14 to $36 per seat a month, both billed per user regardless of usage. Chatwoot's open-source version has no per-seat license fee at all, so the savings scale directly with headcount once you are past the effort of running it yourself.
What are the main shared inbox vendors?
