Manus Adds Multi-Account Gmail and Calendar Integration

Manus, the AI-driven autonomous agent platform, has rolled out a major update allowing users to connect multiple Gmail and Google Calendar accounts to the system. This development, announced on June 8, 2026, aims to streamline workflows that require access to multiple accounts for tasks, scheduling, and project coordination.

Previously, users were limited to a single Google account per Manus workspace. Now, users can integrate various accounts—whether personal, work, client, or team-specific—and select which account Manus should act from on a task-by-task basis. For example, Manus can check availability across both a personal and work calendar, then draft a scheduling email from a work Gmail account. Similarly, it can pull context from a client inbox while ensuring responses are sent from the correct identity.

Why This Feature Matters

Managing multiple email and calendar accounts has become the norm for professionals juggling personal, work, and client-related commitments. However, switching between tabs, manually syncing schedules, and ensuring that the right email account is used for communication often lead to inefficiencies and errors.

With this new integration, Manus minimizes these pain points by enabling seamless cross-account workflows. This is particularly beneficial for freelancers, consultants, and project managers who regularly work across different clients and teams. Manus users can now automate recurring tasks, like weekly planning, that leverage multiple inboxes and calendars while maintaining control over which account executes final actions.

Use Cases Highlighted

The update introduces flexibility for a variety of real-world applications:

• Scheduling Across Calendars: Manus can consolidate availability from multiple calendars to prevent double-booking and draft scheduling replies from a specified Gmail account.
• Client-Specific Workflows: Users managing multiple client accounts can pull context from the appropriate inbox, draft summaries, and schedule follow-ups, all while maintaining distinct identities for each client.
• Recurring Workflows: Tasks like weekly reviews can now integrate data from multiple accounts, ensuring a holistic view of work and personal commitments.

Contextual Background on Manus

Manus is a subscription-based AI platform originally developed by Butterfly Effect (Monica.im). Launched in March 2025, the platform distinguishes itself from traditional chatbots by functioning as a general-purpose autonomous agent capable of executing complex, multi-step workflows. These capabilities include web browsing, running scripts, and integrating third-party tools like Gmail and Google Calendar.

Meta announced plans to acquire Manus in December 2025 in a deal reportedly exceeding $2 billion, aiming to incorporate its agent technology into Meta’s AI ecosystem. However, the acquisition faced hurdles, with China blocking the transaction in April 2026, citing national security concerns. Despite these challenges, Manus has continued to expand its feature set, including the recent multi-account upgrade.

The Bigger Picture

As AI tools like Manus grow in functionality, they’re bridging the gap between task automation and human productivity. By enabling multi-account Gmail and Google Calendar integration, Manus positions itself as an essential tool for professionals managing complex, multi-context workflows. This update not only improves efficiency but also highlights the platform’s focus on user-centric flexibility.

For Manus users, the ability to connect multiple accounts is a step toward reducing friction in daily operations. It enhances the platform’s appeal among freelancers, consultants, and organizations with diverse account needs—all without compromising control or context.
