Send Email via uSpeedo Sending Channel

Before You Use (Installation Considerations)

1. Platform key handling: Confirm how your AI platform handles credentials and conversation history. Do not paste long-lived keys into chat unless the platform provides a temporary or secret input mechanism.
2. Key practice: Prefer short-lived or least-privilege API keys for testing; rotate keys after testing if they were exposed.
3. Credentials in metadata (OpenClaw): Frontmatter declares metadata.openclaw.requires.env (ACCESSKEY_ID, ACCESSKEY_SECRET) and metadata.openclaw.primaryEnv (ACCESSKEY_SECRET). Integrations and registries should surface these so users know key requirements before use.
4. Email content: The skill sends the user’s raw plain text or HTML. Avoid sending sensitive content or unvalidated HTML to prevent abuse or leakage.
5. If in doubt: If you cannot verify how the platform stores keys or how uSpeedo is used, treat credentials as highly sensitive and use one-time or test credentials only.

Platform persistence: This skill instructs the agent not to persist keys, but conversation context or platform logs may still retain user input. Prefer platforms that support ephemeral or secure credential input.

Credentials and Environment Variables

Prefer environment variables over user-provided credentials whenever possible.
