MailHub – Unified Email

Bring work, personal and subscription email together. MailHub connects your existing accounts with a unified inbox, conversation view, a message composer and attachments.

YOUR ACCOUNTS, IN ONE PLACE
Connect QQ Mail, 163 Mail, personal Outlook / Hotmail or compatible IMAP/SMTP accounts. Browse all inboxes together or focus on an account and folder.

READ AND REPLY
Follow conversations, reply to everyone or forward a message. Insert photos into your email or add file attachments. Keep drafts on your device and return to them later.

LOCAL MODE
Connect directly to providers. Credentials use system secure storage; messages are cached on your device. Read downloaded bodies and attachments offline. MailHub checks for new messages in the foreground and supports pull to refresh.

OPTIONAL PERSONAL SERVER
Deploy your own MailHub server and connect your phone by QR code or connection link. Share server mailboxes or explicitly copy selected account settings and saved provider app passwords in either direction. Original accounts are retained; other accounts are not uploaded automatically. Message caches, drafts and pending-send queues are not copied. OAuth accounts require authorization on the destination. Shared server mode requires internet access. Your server stores and processes the selected credentials and mail cache, accessible to its administrator. MailHub offers no hosted mail cloud.

ACCOUNT REQUIREMENTS
QQ and 163 require IMAP/SMTP and a provider app password. Setup instructions are available in the app. Personal Outlook / Hotmail accounts authorize through Microsoft and connect directly to Microsoft Graph on the device, without IMAP/SMTP or forwarding. Gmail is limited to approved accounts. Background checks depend on the operating system, network and permissions; immediate notifications are not guaranteed.

PRIVACY NOTES
External images load automatically by default and can reveal your IP address to the image source. Disable automatic loading in reading settings if preferred. Local mail caches do not yet have application-level database encryption. Protect access to your device.
