Converting email templates

Purpose

Automatically convert email templates from other email service providers into Mailtrap-compatible Handlebars syntax. Handles both deterministic pattern conversions (via a Python script) and complex edge cases (via LLM intelligence).

Related skills: using-email-templates (Handlebars syntax, API template send), sending-emails (stream bases and auth), authorizing-api-requests (tokens, env vars, account_id resolution — needed when creating templates or sending via the Templates API after conversion).

Input

• Source provider (required): sendgrid, mailgun, mandrill-handlebars, mandrill-mergetags, postmark, brevo, or ses
• Input: a single template file path, a directory of .html template files, or raw HTML pasted inline
• Output directory (optional): defaults to a /converted/ subdirectory next to the input

If the user does not specify the source provider, ask before proceeding. If the user provides template HTML inline (pasted in chat), save it to a temporary .html file first.
