What is law firm email management software?

Law firm email management software helps attorneys and staff organize firm communication by client, matter, lead, mailbox, and workflow. Legasus Mail connects Gmail, Outlook, and Microsoft 365 to your matters, intake records, files, tasks, and AI-assisted summaries.

Can Legasus connect to Gmail and Outlook?

Yes. Legasus Mail is designed to connect with Gmail, Google Workspace, Outlook, and Microsoft 365 so firms can keep using their existing email providers while working inside Legasus.

Do I have to stop using my regular inbox?

No. Your team can continue using Gmail or Outlook while Legasus keeps email synced with the firm's matters, intake records, and communication history.

Can emails be linked to matters?

Yes. Email threads can be linked to matters so attorneys and staff can view related communication, attachments, activity, and AI summaries from the case record.

Can incoming emails become intake records?

Yes. New lead emails can be surfaced for intake review so the firm can assign follow-up, connect the conversation to a lead or matter, and keep the original communication history organized.

Does Legasus Mail include AI?

Yes. Legasus Mail includes Mail AI, which can summarize threads, suggest next steps, recommend matter links, classify senders, and prepare replies for approval. For a deeper look at the AI workflow, visit the Mail AI page.

Does AI send emails automatically?

No. Mail AI can prepare drafts and recommendations, but emails require user approval before they are sent.

Can Legasus save email attachments to matter storage?

Yes. Attachments from relevant emails can be saved to firm storage and associated with the right matter, helping reduce manual downloading, renaming, and re-uploading.

Can shared inboxes like intake@firm.com be managed?

Yes. Admins can manage shared firm mailboxes and control which users can view, draft, reply, or send from those addresses.

Can ethical walls restrict email access?

Yes. Legasus enforces access controls so sensitive matter communication is only visible to users with the appropriate permissions.

What happens if an email is deleted?

Deletion behavior follows the firm's configured policies. Legal holds and retention controls can help prevent protected communication from being removed when preservation is required.

Can Mail AI learn my writing style?

Legasus Mail can learn user communication preferences over time to suggest drafts that better match tone, structure, and response style. The user still reviews, edits, and approves messages before sending.

Is this only for large law firms?

No. Legasus Mail is useful for solo attorneys, growing firms, intake-heavy practices, and multi-user teams that need better visibility across email, matters, leads, and documents.

THE PROBLEM

Law firms run on email. But email was never built for case management.

Leads arrive in one inbox. Court notices land in another. Attachments get downloaded, renamed, and re-uploaded. Important conversations stay buried in personal mailboxes instead of living with the matter they belong to.

Missed intake leads

New case opportunities can sit unnoticed in crowded inboxes.

Lost matter history

Important conversations stay disconnected from the case record.

Manual filing work

Staff waste time saving attachments, copying notes, and logging updates.

SYNC

Use Gmail and Outlook. Work inside Legasus.

Connect Gmail, Google Workspace, Outlook, or Microsoft 365. Your team can send and receive email inside Legasus while still using their native inbox when needed. Threads stay synced, conversations stay searchable, and mail can be connected directly to matters, intake records, tasks, and firm storage.

INTAKE

Turn new emails into organized intake opportunities.

When a new lead emails your firm, Legasus can identify the sender, summarize the request, flag the message as a potential intake, and surface it inside your Intake page for review. Your team can confirm the lead, assign it, start the intake workflow, and keep the original conversation attached from day one.

MATTERS

Every important conversation belongs with the case.

Link an email thread to a matter once, and future replies can stay connected. Attorneys and staff can open a matter and see related emails, attachments, notes, activity, and AI summaries in one place.
