Unfoldmail

UnfoldMail is a free, open-source team email application from Web Network Solutions. It gives your organization webmail, administration and optional AI features, and it runs entirely inside your own Cloudflare account. The software is MIT licensed, so there is no per-seat license fee: you pay Cloudflare and any optional AI providers for what you actually use.

What's included:

• Webmail with folders, search, attachments, contacts, and calendar • Organization administration, user management, and activity reports • Optional AI assistant with administrator-controlled configuration • Guided Email setup wizard: paste a scoped Cloudflare API token and it enables Email Sending, configures mail DNS, and applies Worker routing rules • Per-user mailbox storage on Durable Objects, D1 for central records, R2 for message content, and queues for background processing • Device-password and mail-protocol APIs, with the optional UnfoldMail Connect gateway for IMAP/SMTP access

Grow your team. Keep email costs in your control.
