Employees come and go. What they know shouldn’t.

Years of decisions, commitments and business relationships live in your employees’ inboxes. When they leave, that knowledge often leaves with them. HandoverMail securely stores important emails, preserves the knowledge behind them and automatically creates clear, practical handover notes for anyone who needs them. Every claim links back to the message it came from.

Product

Two workflows. One archive.

Choose how you want to archive email. Archive a mailbox when someone leaves, or keep your entire team continuously archived. Every mailbox can be managed individually and updated whenever your needs change.

When an employee leaves, someone simply starts the archive. HandoverMail securely captures the mailbox, creates a complete handover, shares it with the right people and locks the archive when everything is finished.

HandoverMail can automatically archive mailboxes on a schedule you choose. It captures only what’s changed since the last archive, updates the existing record and logs every run in a complete audit trail.

Confirming the two-week extension from CBN. The revised filing is now due Feb 28, 2026. Please make sure the annexure A revisions land in the pack before we send.

Also — the auditors flagged the classification note; I’ll draft a reply and cc you both before the end of the week.

Two attachments below: the revised annexure and the classification worksheet Rita’s team just finalised.

Audit log

Every state change, written down.

Each transition on every mailbox is an append-only row: timestamp, actor, prior state, next state, reason. The log itself is signed. If a regulator asks who paused what and why, the answer is one query away.

Platform

What it does

HandoverMail helps organisations preserve the knowledge locked away in employee inboxes. Archive email, search years of conversations, generate AI powered handovers and securely export data from a single platform. Whether you use our cloud service or run it on your own infrastructure, the experience is the same.

How it works

Mailbox in, handover out

From mailbox to handover in four simple steps. Each stage works independently, so if one step needs attention, the archive continues safely without starting over.

01

Connect & import

Connect your email provider, choose the mailboxes and date range, then start the import.

02

Archive & organise

Emails are securely archived, grouped into conversations and indexed so they’re easy to search later.

03

Extract knowledge

AI identifies important decisions, commitments, action items and open questions. Every insight links back to the original email for verification.

04

Create the handover

Generate a handover from real email conversations, review the supporting evidence, approve it and share it with the people who need it.

Built on evidence, not assumptions. Every insight is backed by the original email. If it can’t be traced to a source message, it isn’t included in the handover.

Editions

Same product. You choose where it runs.

Choose our fully managed cloud service or deploy HandoverMail on your own infrastructure. Every feature is available in both editions, so you are choosing where it runs, not what you get.

Cloud

Get started in minutes while we manage the infrastructure for you.

  • Connect your email provider and start archiving in just a few steps
  • Keep your data in the region that best meets your compliance and residency requirements
  • Choose the level of isolation that suits your organisation, including dedicated deployments
  • We take care of updates, backups, monitoring and disaster recovery
  • Your archive is never locked away. If your subscription ends, it becomes read-only and you can still export your data at any time.

Architecture

How everything fits together.

Your email flows in from the systems you already use, becomes a secure archive and comes out as knowledge people can act on. Select any part of the diagram to see what it does.

What you get out

Data residency

Your data stays where you choose.

Choose your preferred data region during setup. Your emails, attachments, AI knowledge, backups and audit logs are all stored there. If any service ever needs to process data outside your chosen region, we will tell you exactly what, why and where, before you enable it.

Need even greater control? Dedicated deployments give you stricter data isolation, while self-hosted deployments keep everything entirely within your own infrastructure.

Be ready before your next handover.

Book a session with our engineers. We will import a mailbox, search the archive, and generate a handover from real email conversations so you can see exactly how it works. Every insight is backed by the original emails.
