Gmail email triage software.
Sorted before you sit down.
Gmail email triage built for teams and operators. Connect Google Workspace for automatic labeling, SLA tracking, thread summaries, and review-ready reply drafts without replacing your Gmail client. Consumer Gmail connects through the browser extension or forwarding.
// GOOGLE OAUTH · KEYLESS DELEGATION · NO PASSWORDS
Choose the Google connection that fits
Workspace teams get two native connection modes. Browser extension and forwarding paths remain available for consumer Gmail and Workspace accounts.
Tenant-owned Google OAuth
Your Google Workspace organization owns the OAuth configuration and authorization. Mailtwine synchronizes explicitly connected mailboxes through scoped Gmail access.
Keyless domain delegation
Workspace administrators can delegate selected mailboxes through a service account without uploading or storing JSON service-account keys.
Inside Gmail in Chrome
The Mailtwine extension adds triage, summaries, and drafting beside the Gmail thread already open in your browser.
Into the command center
Set up auto-forwarding in Gmail's own settings and incoming mail lands in Mailtwine's queue: classified, prioritized, summarized, and ready to work.
From connection to controlled workflow
Choose a connection
Use Workspace OAuth, keyless service-account delegation, the Chrome extension, or forwarding.
Authorize access
A Workspace administrator completes tenant-owned OAuth or explicitly configures domain-wide delegation.
Select mailboxes
Connect only the Workspace mailboxes that should participate, then let Mailtwine synchronize supported Gmail state.
Set action controls
Keep drafts and actions approval-gated by default, then allow only the automations your team trusts.
No passwords. No downloadable service-account keys.
Tenant-owned OAuth remains under your organization’s control and can be revoked. The keyless service-account mode uses explicit mailbox delegation instead of stored JSON keys. Native synchronization uses the Gmail modify scope.

Mailtwine is the underdog working behind the accounts you already use. No new address. No migration. No swapping one inbox for another. It sorts, drafts, routes, and follows up in the background, then asks for attention only when a decision still needs you.
Connect Google Workspace through tenant-owned Google OAuth or keyless service-account domain-wide delegation, Outlook.com and Microsoft 365 through Microsoft OAuth, Fastmail through JMAP, Helpmonks through its native API, or any standard IMAP mailbox with SMTP for sending. MCP-compatible clients connect over OAuth for mail search, summaries, draft suggestions, routing, and approval review.
