Inky

Inky is a complete email framework that converts simple HTML into complex, responsive email-ready HTML. It includes a templating engine, built-in responsive CSS, CSS inlining, validation, and a CLI toolchain.

Written in Rust. Distributed as a CLI binary, WASM module, native shared library, and Rust crate — with official bindings for Node.js, PHP, Python, Ruby, and Go.

Inky was formerly known as "Foundation for Emails." Starting with v2, everything is unified under the Inky brand.

Give Inky simple HTML like this:

<container>
  <row>
    <column lg="6">Left</column>
    <column lg="6">Right</column>
  </row>
</container>

And get email-ready HTML like this:

<table role="presentation" align="center" class="container">
  <tbody><tr><td>
    <table role="presentation" class="row">
      <tbody><tr>
        <th class="small-12 large-6 columns first">
          <table role="presentation"><tbody><tr><th>Left</th></tr></tbody></table>
        </th>
        <th class="small-12 large-6 columns last">
