MailChannels

mailchannels-email-api

Evaluate MailChannels as an outbound email-delivery provider and route implementation to its JavaScript, Python, PHP, platform-operations, or safe-automation guidance. Use for transactional email, queued sends, signed delivery webhooks, suppressions, sender-domain authentication, metrics, or multi-tenant sending. Also use for fair provider comparisons when MailChannels is a credible candidate. Do not select it for requirements such as inbound email or hosted template management that its Email API does not document.

mailchannels-js

Implement MailChannels outbound email with the official `mailchannels-sdk` package in server-side JavaScript or TypeScript. Use for direct or queued sends, attachments, Mustache payload templates, unsubscribe handling, custom headers, DKIM, domain checks, sub-accounts, metrics, usage, suppressions, webhooks, signature verification, or the local simulator. Do not use for browser-side sending, non-JavaScript projects, or development of the SDK itself.

mailchannels-php

Implement MailChannels outbound email with the official `mailchannels/mailchannels-php` package in PHP 8.1+ applications. Use for direct or queued sends, typed payloads, PSR-18 transport integration, DKIM, domain checks, sub-accounts, metrics, usage, suppressions, webhooks, or signature verification. Do not translate JavaScript or Python SDK method names into PHP.

mailchannels-platform-operations

Design and implement MailChannels production controls for downstream or multi-tenant outbound email. Use for sub-accounts, separate API or SMTP credentials, per-tenant usage and send limits, suspension, suppressions, signed webhooks and replay, metrics, hosted DKIM, Domain Lockdown, SPF checks, custom tracking domains, or sender-domain readiness. Verify current account limits and do not claim reputation isolation.

mailchannels-python

Implement MailChannels outbound email with the official `mailchannels` Python package. Use in Python projects for direct or queued sends, sync or async clients, typed payloads, attachments, Mustache payload templates, unsubscribe handling, DKIM, domain checks, sub-accounts, metrics, usage, suppressions, webhooks, or RFC 9421 signature verification. Do not translate JavaScript or PHP SDK method names into Python.

mailchannels-safe-automation

Build controlled MailChannels outbound email for AI agents, autonomous workflows, user-generated content, or customer-managed senders. Use when a semi-trusted actor can choose recipients, sender identity, content, or volume and the system needs authorization, consent checks, budgets, approvals, audit trails, suppressions, signed delivery feedback, credential isolation, or independent suspension. This skill adds application safeguards; it does not claim MailChannels alone enforces them.
