A real mail client, synced both ways
Read, reply, file and search as in Outlook or Gmail. Supported mail actions sync in both directions. Your case organization and internal collaboration stay in the workspace.

What it is
Your mailbox, a shared case file
Your mailbox, a shared case file
and a ticket system. In one.
Eleon is an open-source, self-hosted email case management tool for Outlook and Gmail. It syncs both ways with your mailbox, puts the related email threads of one matter into one case on a shared timeline, and runs your team's work like a ticket system, with owners, statuses, reply targets and automations.
Cases with every thread on one timeline
The customer, the supplier and your colleagues stay in their own conversations, side by side on one clock, with the gaps between them visible.

Case numbers, owners, statuses, groups, reply targets and automation rules. Customers simply keep replying by email.
How it works for a team
The point
Outlook sees threads.
Outlook sees threads.
Your work is cases.
One matter is never one thread. It is the customer, the supplier, a colleague, the lab, a forwarded PDF. Each lives in its own conversation, often in someone else's mailbox, and nobody sees the whole picture.

One case. Every conversation in order, the next step and who owns it. A teammate with access can pick it up.
Two-way sync
Do it here.
Do it here.
It's done in Outlook too.
Your Outlook or Gmail mailbox stays the source of truth. Supported email actions in Eleon sync with your mailbox, and mailbox changes are brought back here in the background. Cases, internal notes and checklists stay in the workspace. Exact capabilities depend on the mail provider.
- Microsoft push notifications can bring new mail in within seconds when configured; background sync also checks for changes.
- Keep using Outlook or Gmail on your phone alongside the workspace.
- Your actions and any automation rules you enable determine what changes in the mailbox.

Works like a ticket system
A helpdesk for every team.
A helpdesk for every team.

Owners & status
Separate Responsible and Handled by roles, custom statuses within Open, Waiting and Closed, and waiting cases that reopen when a customer replies.
Shared inboxes
info@ and support@ for the whole team: claim a conversation, see Mine, Unassigned and Others'.

Groups & templates

Inside a case
Everything about a matter.
Everything about a matter.
In one place.
When something becomes a matter, make it a case: the original threads stay as they are, and come together with the people, the files and the next step.
Parallel threads, one timeline
Conversations with different people, from different mailboxes, sit in their own columns on one shared clock, and you see how long each one waited for the other.
Next step and who you wait on
Every case says what happens next, who does it, and whether it waits on the customer, a supplier or a colleague. "Waiting on supplier" is a list, not a feeling.
Made for a team
Notes beside the emails, @mentions, checklists with dates, holiday cover and a handover when someone leaves.
Files open inside
PDF, Word, Excel, PowerPoint and DXF drawings open in the case. Search finds text in supported PDF and Office attachments, including Greek. Scanned images need a searchable text layer.
Follow-ups that remember
Reminders that stay quiet when the other side answers first, snooze, send later and undo send.
An assistant that reads the case for you
Ask "what did we agree with Anna about delivery?", get a summary, or a reply drafted in the customer's language. It retrieves material within your access, links to the emails it used, and leaves replies for you to review and send.
Agents in the background
Twelve configurable routines cover triage, promises, summaries, next steps, unanswered mail, follow-ups, reply targets, morning briefings, patterns, solutions memory, deals and prepared replies. Some use AI; others use rules.
Take the whole case with you
Export emails, files, notes and history together, or print the case to PDF.
