Manage your tuta.com account

Send, read, and manage emails via Tuta (formerly Tutanota) encrypted email service. Use when user asks to send emails, check inbox, read mail, or do any email operations through their Tuta account. Triggers on phrases like email, send email, check inbox, Tuta, Tutanota, mail, read email, compose email.

Tuta Mail

Interact with Tuta (Tutanota) encrypted email via the undocumented REST API at https://app.tuta.com/rest/. All content is E2E encrypted — the client handles crypto locally.

Prerequisites

Python 3 with: requests, pycryptodome, bcrypt, argon2-cffi.

Install if missing:

bash

python3 -m pip install --break-system-packages requests pycryptodome bcrypt argon2-cffi

Credentials

Store in openclaw.json under skills.entries.tuta-mail.env:

• TUTA_EMAIL — Tuta email address
• TUTA_PASSWORD — account password

Usage

All commands via scripts/tuta_client.py (resolve path relative to this skill directory).

Login (always do first)

bash

python3 scripts/tuta_client.py login \
  --email "$TUTA_EMAIL" --password "$TUTA_PASSWORD" \
  --session-file /tmp/tuta_session.json

Saves session (access token + decrypted keys) to the session file. Reuse until it expires.

List Inbox

bash

python3 scripts/tuta_client.py inbox \
  --session-file /tmp/tuta_session.json --count 20

Returns JSON array with id, subject, sender, date, unread for each mail.

Read Email

bash

python3 scripts/tuta_client.py read \
  --mail-id "listId/elementId" \
  --session-file /tmp/tuta_session.json

Use the id from inbox listing. Returns decrypted subject, sender, date, body.

Send Email (External Recipients)

bash

python3 scripts/tuta_client.py send \
  --to "[e-mail]" \
  --subject "Subject line" \
  --body "Email body text" \
  --sender-name "Display Name" \
  --session-file /tmp/tuta_session.json

Sends non-confidential email to external (non-Tuta) recipients. Creates draft then sends.

Workflow

1. Login once per session → cache /tmp/tuta_session.json
2. If any command returns auth error (401/403), re-login
3. For inbox checks: login → inbox → optionally read specific mails
4. For sending: login → send

Limitations

• Tuta-to-Tuta emails: Sending to other Tuta users requires public key exchange (not yet implemented). Reading Tuta-to-Tuta received mail works.
• Attachments: Not yet supported for sending.
• API versioning: The v header is set to 84; may need updating if Tuta changes their API version.
• Newer accounts: Argon2id key derivation is supported but less tested than bcrypt (legacy).
