ShareMail vs Missive
Missive is the best-liked product in this category and we are not going to pretend otherwise. It is also a different shape: a complete email client with team chat and several channels. If you want the Gmail you already have, plus collaboration, the maths changes.
What Missive does well
- Team chat built into the same app as the inbox, which people genuinely love
- Multi-channel: SMS, WhatsApp and social alongside email
- A polished, fast client with a long track record and SOC 2 Type II

| Channels | Email only, on purpose | Email, SMS, WhatsApp, social |
| Where your email lives | In your Gmail. ShareMail is a layer on top and never becomes the system of record | Synced into Missive, which becomes the client you work in |
| Mail delivery path | Untouched. Gmail sends and receives, we never sit in the path | Missive sends through its own infrastructure |
| If you leave | Disconnect. Your mail is already in Gmail; comments, tags and assignments export in full | Export what their plan allows, then migrate |
Missive column: their published pricing and documentation, read September 2026 (source). Pricing and packaging change, so verify current terms with Missive directly before you decide. ShareMail's column describes the product as it runs today plus the commitments in our pledge; anything not yet shipped says so. We like Missive. If the comparison you are running is "which is the better email client", buy Missive. Ours is "do you want to replace Gmail or add to it".
Choose Missive if…
You want team chat and several channels in one app, and you are happy replacing your mail client rather than adding to Gmail.
Choose ShareMail if…
Your team answers email out of Gmail, you want comments, assignments, shared drafts and rules on top of it, and you would rather not pay per seat for a platform, or for AI you did not ask for. The whole inbox is on every plan, from $6 a seat.
