What it does

The plugin pairs an 11-tool async IMAP and SMTP MCP server called yandex-mail with three skills. check-inbox reads unread mail and sorts it into categories like business, financial or notifications with an urgency priority. compose-email drafts a new business email with an HTML signature, a logo and inline images, and shows the draft for confirmation before sending. reply-to-email finds the original email and replies with a quote, preserving the thread via Re, In-Reply-To and References headers. It supports Yandex Mail, including Yandex 360 for Business with custom domains. An email is actually sent only after the user confirms the shown draft with a word like yes.

Who it is for. For people who handle business email on Yandex Mail and want Claude to sort the inbox and draft signed replies.

Good fit when

  • You want a quick unread-mail triage by urgency and category
  • You want replies and new emails with a consistent HTML signature and logo
  • You are fine with an email only going out after explicitly confirming the draft

Not a fit when

  • You are on Windows without WSL or MSYS: the platform was not tested
  • You do not want to give the plugin send access even with confirmation

Example request

Check my mail and show which emails need a reply today

Limitations

You need a Yandex app password rather than the regular account password, and IMAP access enabled in Yandex Mail settings. It is tested on macOS and Linux; Windows was not tested and the author says it should work via WSL or MSYS. Setting up the signature requires company details and a path to a logo.

How to disable. Remove the plugin with claude plugin remove claude-yandex-mail, or delete the .plugin file from Cowork.

FAQ

Does the email send as soon as Claude drafts it?

No, Claude shows the draft and sends it only after the user explicitly confirms.

Will a regular Yandex Mail password work?

No, you need a separate Mail-type app password from id.yandex.ru security settings.

How is the Yandex Mail plugin for Claude different from other mail MCP servers?

The plugin connects the yandex-mail MCP server with 11 asynchronous IMAP and SMTP tools to three skills. check-inbox reads unread mail and sorts it into categories, the others prepare drafts with an HTML signature and replies with quoting.

Is the email sent right after composing and will my regular mail password work?

Check the draft before sending: sending goes through SMTP and the outcome should be confirmed by hand. For IMAP and SMTP Yandex requires an app password, the regular account password will not work. Install by cloning the repository. It works in Claude Code and Claude Desktop. Risk is high.
