SEDNA is a group email solution for enterprise organizations that are looking to significantly reduce their volume of email messages and attachments. Knowing who's read an email, what plan of action is being taken, when that action was taken, and how the team responded is a cumbersome and often inefficient experience with most email clients. SEDNA is not like other email solutions. SEDNA makes managing team email a collaborative, transparent and efficient experience. Instead of forwarding or copying team members on a critical message, and then following a long chain of separate replies, SEDNA allows your team to work from the original copy, with every attachment, tag, and comment visible to everyone on your team.

- Stay organized by tagging messages with: Reference IDs, People, and Taxonomy.

- Get involved by contributing to inline discussion thread of every message. No more cc's!

- Keep up on what's going on with Read Messages and Activity Logs.

- Automatically tag messages upon ingestion based on third party data.

- Easily link your workflow documents for sharing with your team or customers.

- Integrate with your back office system to automatically filter new messages to the appropriate users.

- Populate external data directly into an email based on a reference ID.

- Use SEDNA's search API to integrate external systems directly into the application.

- Prioritize your task list and that of your team's with To-Do tags.

- Permanently and securely store terabytes of email messages.

- Work independently from your standard email services.

- Whether you already use O365, Outlook, Gmail, Lotus Notes, or your own mail server, SEDNA just works.

- Rest easy knowing that SEDNA can handle high volumes of incoming mail without impacting service or performance.
