Uspeedo Email Sending Channel

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.

Obtaining environment variables (ACCESSKEY_ID / ACCESSKEY_SECRET): Go to Email API Key management to create or view API keys, and set them in .env or your system environment. If both environment variables and user-provided keys are present, environment variables take precedence. Keys are for authenticating the current request only; do not cache or persist them, and do not commit .env to version control.

Usage Restrictions (Mandatory)

• Do not cache or persist user-provided sensitive information: ACCESSKEY_ID and ACCESSKEY_SECRET are for authenticating the current request only. They must not be written to session memory, knowledge base, cache, logs, code, or any storage that can be read later; after the call completes they are considered consumed and must not be retained or referenced.
• No hidden sending: Never send email automatically. Always require an explicit user confirmation in the current turn for sender, recipients, subject, and final content.
• No credential echoing: Never print, log, or repeat Authorization header, ACCESSKEY_SECRET, or full raw request/response payloads.
• Fail closed on missing credentials: If environment variables are unavailable and user does not provide valid keys, stop and ask for required setup instead of attempting partial calls.

Mandatory Safety Gates Before Sending

Run these checks before every send request:

1. Parameter confirmation gate (required):
   • Resolve SendEmail first (see "Get Sender List and SendEmail resolution" below), then confirm SendEmail, all TargetEmailAddress, Subject, and Content with the user in the same turn.
   • If any required field is missing/ambiguous, stop and ask for correction.
2. Recipient format gate (required):
   • Reject obviously invalid emails (missing @, missing domain, empty items, non-string entries).
   • De-duplicate recipients before sending.
3. HTML safety gate (required for HTML content):
   • If content is HTML, warn the user that active content is not allowed.
   • Reject or require user rewrite when HTML contains risky patterns such as <script, <iframe, <object, <embed, <form, inline event handlers like onload=, or javascript: URLs.
   • Prefer plain text when possible.
4. Scope gate (required):
   • This skill is for user-requested transactional/notification sending via uSpeedo API only.
   • If the user asks for deceptive, phishing, credential-harvesting, or policy-violating email, refuse to send.

When to Use

• When the user asks the Agent to "send email" or "send an email"
• When the user provides recipients, email content, and is willing to provide uSpeedo platform keys

When asking the user to provide or confirm any send parameters (recipients, sender, subject, content, credentials), always show the guidance in "Notes for Users" (ACCESSKEY_ID/ACCESSKEY_SECRET obtain link and deliverability/domain link).

Prerequisites

1. Registration: The user has registered an account at uSpeedo.
2. Obtain keys (environment variables): Get API keys from Email API Key management and set them as ACCESSKEY_ID and ACCESSKEY_SECRET (e.g. in .env).

Before calling the send API, confirm with the user that these steps are done; if not, direct them to register and obtain keys at the link above.

Information the User Must Provide

Get Sender List and SendEmail resolution

Official API reference: GetSenderList.

When to call: After credentials are available and before SendEmail, unless the user has already given a definitive SendEmail for this send (then you may skip the list call).

Endpoint: GET https://api.uspeedo.com/api/v1/email/GetSenderList

Headers:

• Accept: application/json
• Authorization: Basic <base64(ACCESSKEY_ID:ACCESSKEY_SECRET)>

Query string (common defaults; all parameters are query-based per docs):

• Page=0 (page index starts at 0)
• NumPerPage=20 (max 200)
• OrderBy=create_time or update_time
• OrderType=desc

Optional filters: Email, Domain, SenderType, FuzzySearch — use when the user wants a specific sender.

Response (user-safe handling):

• On success, RetCode is 0. Read Data (array of sender objects).
• Each item includes at least: Email, Status (e.g. 1 enabled, 0 disabled), Alias, etc.

Default resolution for SendEmail (if user did not specify):

1. If Data is empty or missing: stop; tell the user to add/enable a sender in the Email console / domain & sender settings, or provide SendEmail explicitly.
2. Prefer the first item in Data where Status === 1 (enabled). If none, fall back to the first item in Data and warn that it may be disabled.
3. Set SendEmail to that item’s Email string.
4. User override: If the user supplies SendEmail, use it (after format validation). Optionally call GetSenderList with Email filter to verify it exists when helpful.

Confirmation: Present the resolved SendEmail (and optionally Alias / domain from the same row) to the user with recipients, subject, and content before calling SendEmail.

How to Call SendEmail

Endpoint: POST https://api.uspeedo.com/api/v1/email/SendEmail

Headers:

• Content-Type: application/json
• Authorization: Basic <base64(ACCESSKEY_ID:ACCESSKEY_SECRET)>

Request body (JSON):

{
  "SendEmail": "sender@example.com",
  "TargetEmailAddress": ["recipient1@example.com", "recipient2@example.com"],
  "Subject": "Email subject",
  "Content": "<html><body>...</body></html>",
  "FromName": "Sender display name"
}

• Content: Plain text or HTML. Use the user’s content as-is for plain text; use directly for HTML.
• Content safety: For HTML, pass content only after the "HTML safety gate" above is satisfied.
• TargetEmailAddress: Array with at least one recipient email.

Example (JavaScript/Node)

Credentials are read from environment variables first; params is used as fallback. Resolve SendEmail via GetSenderList when sendEmail is omitted.

function basicAuthHeader(accessKeyId, accessKeySecret) {
  const token = Buffer.from(`${accessKeyId}:${accessKeySecret}`).toString('base64');
  return `Basic ${token}`;
}

/** GET GetSenderList — see https://uspeedo.com/docs/products/email/api/GetSenderList */
async function getSenderList(accessKeyId, accessKeySecret, query = {}) {
  const qs = new URLSearchParams({
    Page: '0',
    NumPerPage: '20',
    OrderBy: 'create_time',
    OrderType: 'desc',
    ...query
  });
  const url = `https://api.uspeedo.com/api/v1/email/GetSenderList?${qs}`;
  const res = await fetch(url, {
    method: 'GET',
    headers: {
      Accept: 'application/json',
      Authorization: basicAuthHeader(accessKeyId, accessKeySecret)
    }
  });
  return res.json();
}

function pickDefaultSendEmail(listResponse) {
  const rows = listResponse?.Data;
  if (!Array.isArray(rows) || rows.length === 0) return null;
  const enabled = rows.find((r) => r && r.Status === 1 && r.Email);
  const first = rows.find((r) => r && r.Email);
  return (enabled || first)?.Email ?? null;
}

async function sendEmailViaUSpeedo(params = {}) {
  const accessKeyId = process.env.ACCESSKEY_ID || params.accessKeyId;
  const accessKeySecret = process.env.ACCESSKEY_SECRET || params.accessKeySecret;
  const {
    sendEmail: userSendEmail,
    targetEmails,
    subject,
    content,
    fromName = ''
  } = params;

  let sendEmail = userSendEmail;
  if (!sendEmail) {
    const listJson = await getSenderList(accessKeyId, accessKeySecret);
    if (listJson?.RetCode !== 0) {
      return { error: 'GetSenderList failed', detail: listJson };
    }
    sendEmail = pickDefaultSendEmail(listJson);
    if (!sendEmail) {
      return { error: 'No sender in GetSenderList; add a sender in console or pass sendEmail' };
    }
  }

  const auth = Buffer.from(`${accessKeyId}:${accessKeySecret}`).toString('base64');
  const res = await fetch('https://api.uspeedo.com/api/v1/email/SendEmail', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      Authorization: `Basic ${auth}`
    },
    body: JSON.stringify({
      SendEmail: sendEmail,
      TargetEmailAddress: Array.isArray(targetEmails) ? targetEmails : [targetEmails],
      Subject: subject,
      Content: content,
      ...(fromName && { FromName: fromName })
    })
  });
  return res.json();
}

Example (curl)

Use environment variables ACCESSKEY_ID and ACCESSKEY_SECRET (e.g. from .env or export). If unset, replace with your keys for testing only.

List senders (before send) — GetSenderList:

curl -s -X GET "https://api.uspeedo.com/api/v1/email/GetSenderList?Page=0&NumPerPage=20&OrderBy=create_time&OrderType=desc" \
  -H "Accept: application/json" \
  -H "Authorization: Basic $(echo -n "${ACCESSKEY_ID}:${ACCESSKEY_SECRET}" | base64)"

Parse Data[0].Email (or first Status-enabled row) for SendEmail, unless the user sets SendEmail manually.

Send email:

curl -X POST "https://api.uspeedo.com/api/v1/email/SendEmail" \
  -H "Content-Type: application/json" \
  -H "Authorization: Basic $(echo -n "${ACCESSKEY_ID}:${ACCESSKEY_SECRET}" | base64)" \
  -d '{
    "SendEmail": "sender@example.com",
    "TargetEmailAddress": ["recipient1@example.com", "recipient2@example.com"],
    "Subject": "Welcome to USpeedo Email Service",
    "Content": "<html><body><h1>Welcome</h1><p>This is a test email.</p></body></html>",
    "FromName": "USpeedo"
  }'

Security Notes

• Prefer environment variables (ACCESSKEY_ID, ACCESSKEY_SECRET) over user-provided credentials whenever possible. Get keys: Email API Key management
• Do not log or display ACCESSKEY_SECRET in plain text in frontends or logs.
• The Agent reads keys from environment variables or user input for the current request only; do not persist them to code, docs, or any cache.
• Do not store ACCESSKEY_ID or ACCESSKEY_SECRET in session context or reuse them in later turns.
• Do not include credentials in examples that are rendered to end users except placeholder names.

Reporting API Response to the User

• Report only user-safe outcome: success or failure, and non-sensitive fields such as RetCode, Message, RequestUuid, SuccessCount.
• Do not echo raw response bodies that might contain tokens, internal IDs, or other sensitive data. Do not log full API responses that include credentials or secrets.

Brief Workflow

1. Confirm the user has registered on uSpeedo and obtained keys. Environment variables / key management: Email API Key management.
2. Resolve credentials: use ACCESSKEY_ID and ACCESSKEY_SECRET from environment (or .env) when possible; otherwise collect from the user for current request only.
3. Resolve SendEmail: If the user provided a sender address, validate format and use it. If not, call GET .../GetSenderList, apply the default resolution (first enabled sender’s Email, else first row), or stop if the list is empty.
4. Collect or confirm: recipients, subject, content (text/HTML), FromName (optional). Always confirm the final SendEmail with the user if it came from the list.
5. Run all "Mandatory Safety Gates Before Sending" checks (confirmation, recipient format, HTML safety, scope).
6. Call POST https://api.uspeedo.com/api/v1/email/SendEmail with Basic authentication.
7. Report only the user-safe outcome to the user (see "Reporting API Response to the User" above); do not echo raw response bodies that may contain sensitive data.

When prompting the user to provide or confirm send parameters, always include the guidance below (see "Notes for Users"). Show these hints every time you ask for recipient, sender, subject, content, or credentials.

Notes for Users

• ACCESSKEY_ID and ACCESSKEY_SECRET: Obtain from Email API Key management.
• Sender address (SendEmail): If you do not specify a sender, the skill uses GetSenderList to pick a default (first enabled sender). You can always set SendEmail yourself.
• Deliverability: For better sending results, configure your own sending domain: Domain setting.
