Documentation
Environment
Required: MAILCHANNELS_API_KEY (send in X-Api-Key) MAILCHANNELS_ACCOUNT_ID (aka customer_handle) Optional: MAILCHANNELS_BASE_URL (default: https://api.mailchannels.net/tx/v1), MAILCHANNELS_WEBHOOK_ENDPOINT_URL
Domain Lockdown (DNS)
Create a TXT record for each sender domain: Host: _mailchannels.<your-domain> Value: v=mc1; auid=<YOUR_ACCOUNT_ID>
API Quick Reference
Base URL: ${MAILCHANNELS_BASE_URL:-https://api.mailchannels.net/tx/v1} Send: POST /send Send async: POST /send-async Webhook: POST /webhook?endpoint=<url>, GET /webhook, DELETE /webhook, POST /webhook/validate Public key: GET /webhook/public-key?id=<keyid>
Sending Email
Minimum payload fields: personalizations, from, subject, content. Use /send for normal traffic and /send-async for queued/low-latency; both produce webhooks. Persist MailChannels correlation IDs (e.g., request_id).
Delivery Events (Webhooks)
MailChannels POSTs a JSON array. Common fields: email, customer_handle, timestamp, event, request_id. Bounce fields often include: recipients, status, reason, smtp_id.
Moltbot Hooks Routing
Enable hooks in ~/.clawdbot/moltbot.json. Map /hooks/<path> to an agent action via hooks.mappings and optional transform. Enroll the public endpoint in MailChannels /webhook?endpoint=....
Webhook Signature Verification
Headers: Content-Digest, Signature-Input, Signature. Steps: Parse Signature-Input (name, created, alg, keyid). Reject stale created values. Fetch public key by keyid. Recreate the RFC 9421 signature base. Verify ed25519 signature (avoid hand-rolling). Also verify JSON body is an array and every event has customer_handle == MAILCHANNELS_ACCOUNT_ID.
Correlation + State Updates
Store your internal message ID + MailChannels IDs (e.g., request_id, smtp_id). Update delivery state from events: processed, delivered, soft-bounced, hard-bounced, dropped. Operational tips: respond 2xx quickly, process async, store raw events, dedupe retries.
Category context
Code helpers, APIs, CLIs, browser automation, testing, and developer operations.
