What this skill does
Sending emails (Mailtrap) Overview Mailtrap sends live email over Email API (REST) or SMTP. Two streams apply for API/SMTP: Transactional (non-promotional, app-generated) and Bulk (promotional / marketing volume). Batch is not a third stream: it is how you submit many messages in one request on whichever stream matches the content. Campaigns are a separate product path for promotional mail to Mailtrap contacts. Pair this sheet with the Transactional / Bulk developer pages when building or debugging integrations (including with AI-assisted coding). How to integrate (preference order) Preferred order: 1. Plugin or integration for the user's platform (no-code or minimal-config) where available 2. Official SDK for your language when one exists (maintained clients, typed helpers, less room for URL/auth mistakes). 3. HTTP Email API when there is no SDK or the SDK does not fit (direct POST to /api/send or /api/batch with JSON). 4. SMTP only when you really need it (legacy stack, host/platform that only speaks SMTP, or hard constraints that rule out HTTP).
