OpenMailBot
Most email AI asks you to hand a vendor standing access to your mailbox. This one runs on your server instead.
Overview
For a law firm, a clinic, a bank or a government department, granting a third-party service read and write access to executive mail is not a trade-off to weigh. It is simply not available.
OpenMailBot inverts the arrangement. The server is yours, the data directory is yours, and the model credentials are yours. What the user sees is an add-in inside the mail client they already use — Gmail, Thunderbird or Outlook — so nothing about their day changes.
The useful part is context. A reply is rarely answerable from the thread in front of you; the relevant detail is in a different thread from four months ago, or in one your colleague is on. OpenMailBot retrieves that before it drafts.
Capabilities
What OpenMailBot does
Inside the client you already use
Add-ins for Gmail, Thunderbird and Outlook. No new inbox, no separate application, no migration.
Thread summarisation
Condenses long, forked correspondence into what was decided, what was promised, and what is still open.
Context from other threads
Retrieves related correspondence when you draft, so the reply reflects what was agreed elsewhere instead of only what is on screen.
Drafting, labelling and tone
Produces a draft for review, applies labels, and adjusts register — all as suggestions, never as autonomous sends.
Your server, your data
A self-hosted server holds per-user mail data on storage you own. There is no vendor-side copy.
Your choice of model
Runs against multiple model providers, or against a local model when nothing at all may leave the network.
Who it is for
Built for these situations
Regulated professionals
Legal, healthcare, finance and public sector teams whose correspondence cannot leave a controlled environment.
Security-conscious enterprises
Organisations that will not grant a third-party service standing access to executive mail.
High-volume correspondents
Founders, partners and operators managing hundreds of threads where context is expensive to reconstruct by hand.
Deployment
- Self-hosted server — your infrastructure, your data directory.
- Client add-ins for Gmail, Thunderbird and Outlook.
- Hosted or fully local models, depending on how strict the environment is.
- Deployment, integration and policy customisation are part of the engagement.
Questions
Frequently asked
Does it send mail on my behalf?
No. It produces drafts for review. Sending stays a deliberate human action.
Where is my mail stored?
On the server you deploy. There is no vendor-hosted component holding your correspondence.
Can it run with no internet connection?
Yes, when paired with a locally hosted model. That configuration has no external network dependency.
Which mail clients are supported?
Gmail, Thunderbird and Outlook. Other clients are possible but we scope them per engagement rather than claim them here.
