A library is a collection of reusable blocks — hero sections, text areas, product grids, footers, and more — that define the building pieces for your projects. This page covers the ways to create one.
Creating and editing libraries requires the Libraries permission on your team. If you don’t see Libraries in the sidebar, ask a team owner to grant it.

​
Create a new library

1

Open the Libraries section

Click Libraries in the sidebar.
2

Start a new library

Click the New library button and choose Create new.
3

Name it and pick a type

Enter a name and choose the Type — Email or Site (landing pages). The library starts unpublished, so it won’t be available for projects until you’re ready.
The new library opens in the library editor, where you build out its blocks. The New library dialog with the Type dropdown set to Email and a field for the library name

​
Build blocks with chat

The fastest way to fill a new library is to describe what you need in the library editor’s Chat tab. Denada builds blocks with appropriate parameters based on your description, and you can keep chatting to refine the design. Example prompt:
“Create blocks for our e-commerce brand. I need a hero block with a full-width image and headline, a two-column product feature block, a testimonial block, and a simple footer with social links. Use a clean, modern style.”
The more detail you provide about your brand (colors, fonts, tone), the closer the first draft will be to what you need.
You can also connect an external AI agent like Claude Code and have it build or edit the library from your own machine — see Working with AI agents.

​
Start from existing HTML

If you already have HTML — from an existing email, another tool, or a designer — you can bring it into a library you’ve created:
  • In the library editor’s Edit tab, click New and choose New empty block…, then paste your HTML into the block’s HTML editor.
  • Or open the library menu and choose Edit combined HTML to work on all of the library’s block HTML in a single document.
The quality of the result depends on the structure of the source HTML. Well-organized, semantic HTML is the best starting point, and you’ll typically follow up by defining parameters so the content becomes editable.

​
Import a .library file

Libraries can be exported to a portable .library file (open any library’s menu and choose Export library) and imported into another team.
  1. Click Libraries in the sidebar.
  2. Click the New library button and choose Import library.
  3. Select the .library file. Denada recreates the library with all of its blocks and parameters.

​
Work with the Denada team

For fully custom libraries — especially when you need pixel-perfect brand compliance or complex layouts — the Denada team can build a library tailored to your specifications.
  • Send your existing designs. Provide your current emails or pages and the team will recreate them as a Denada library with full parameterization.
  • Start from a brief. Share your brand guidelines, example designs, and requirements. The team designs and builds the library from scratch.
To get started, reach out to support@heydenada.com or talk to your account manager.

​
After creating a library

Once your library is ready, you can:
  • Continue refining blocks and parameters in the library editor.
  • Turn on Published in the library editor’s Options tab so your team can build with it.
  • Use it in any new project — see Using libraries in projects.
