Manus sends from your own Gmail or Outlook account, under your name, so its emails carry your signature. It reaches your mailbox two ways.
Email typed in the Gmail or Outlook compose window gets the signature saved in that mail app. Google says the Gmail signature is included in messages composed in Gmail on the web, and Outlook applies its signature to new messages and to replies and forwards when you tick those checkboxes.
A connector email skips the compose window. Manus hands the connector the recipients, subject and body, so Gmail's or Outlook's saved signature stays out of it, and Manus adds the signature itself. A Manus project keeps a master instruction that applies to every task in it, which makes it the place for your signature.
Manus connects to custom MCP servers under Settings, Integrations, Custom MCP Servers, with a server URL and an API key or bearer token. Signatoro runs an MCP server that hands an agent your current signature before each email, and it signs you in with OAuth.
Manus's documentation describes keys and bearer tokens for custom servers, so for now the project instruction above is the route for connector email. Signatoro will test the MCP connection with Manus and update this page with the result.
Yes. Manus sends from Gmail typed in its Cloud Browser or in your own browser through Browser Operator, or through its Gmail connector, where it asks you to confirm each send or save it as a draft.
Set your signature in Gmail or Outlook for email Manus writes in the browser. For email it sends through a connector, paste your signature as text into the master instruction of a Manus project and tell Manus to end every email with it.
The email most likely went through the Gmail or Outlook connector, which skips the compose window where the mail app adds its signature. Put your signature in the project's master instruction, then save one email as a draft and check it.
Yes. Manus has prebuilt MCP connectors such as Gmail and Notion, and you add your own server under Settings, Integrations, Custom MCP Servers, with its HTTPS URL and credentials.
