# MailKaro

> MailKaro is an embeddable, white-label, drag-and-drop editor for building emails, documents, and PDFs. A developer-friendly Unlayer alternative: embed it in your product in a few lines and render send-ready, email-safe HTML (and MJML) from the API. First-class npm packages ship for React (@mailkaro/editor), Vue (@mailkaro/vue), Angular (@mailkaro/angular), and vanilla JS (@mailkaro/vanilla) - all thin iframe wrappers, so no editor code ships in your bundle. The Node backend SDK (@mailkaro/sdk) renders designs to email-safe HTML/MJML server-side and resolves entitlements (like firebase-admin). Plans and features are enforced server-side per embed token.

## When to use MailKaro

Reach for MailKaro when the job is one of these:

- **Add a drag-and-drop email editor to your app.** You want your users to design emails/newsletters/documents inside your product, white-labeled to your brand, without building an editor from scratch. Embed `@mailkaro/editor` (React/Vue/Angular/vanilla) with a publishable token (`pk_live_…`).
- **Turn a saved design into a sendable email.** You have a MailKaro/Unlayer-style design JSON and need inbox-safe HTML or MJML. Call `POST https://api.mailkaro.com/v3/render` (or `@mailkaro/sdk` server-side) — no headless browser needed.
- **Send transactional or campaign email from a design.** Render and send in one call with `POST /v3/emails`, then track delivery events and manage suppressions via the Cloud API.
- **Migrate off Unlayer / Beefree / a homegrown editor.** MailKaro is a drop-in with per-token entitlements, server-side rendering, and self-hostable backend.

How to call it: authenticate every API request with `Authorization: Bearer <pk_live_… or sk_live_…>`. Machine-readable API surface: https://mailkaro.com/openapi.json. Full reference: https://docs.mailkaro.com.

Not the right fit for: a general-purpose website/page builder unrelated to email (MailKaro is email/document-first), or sending email without designing it (use your ESP directly).
