Blocks help you reuse email sections instead of rebuilding them from scratch, saving time and keeping your emails consistent.

Whether it's a header, CTA, or footer, you can turn any section into a reusable building block.

What are Blocks?

Blocks are reusable content sections that you can save and insert into any email.

Typical examples:

Logo/header sections
CTA buttons
Product sections
Signatures
Social media footers
Legal / unsubscribe sections

Instead of recreating these every time, just save them once and reuse them anywhere.

Types of Blocks (Important)

Chamaileon now supports multiple block types depending on where and how you want to reuse them:

1. Project Blocks

Saved inside a specific project
Only available within that project
Great for campaign-specific reuse
Design-only - the content is not updating other block occurencies

Use when:
You’re working on a single campaign or email series

2. Master Blocks

Shared reusable blocks across projects
Both content and design updates
Designed for consistency across emails
Can be updated centrally (if using synced versions)

Use when:
You want the same header/footer across multiple emails or campaigns

3. Design System Blocks

Part of your structured email design system
Organized into categories (e.g. Header, Footer, Content)
Built for scalable, consistent email production

Use when:
You’re working with a design system or managing emails at scale.

💡 Tip:
If you're not sure which one to use:

Go with Project Blocks for flexibility
Use Master Blocks for shared elements
Use Design System Blocks for fully standardized workflows

How to save a Block

Select the section (block) you want to reuse
Click “Save Block”
Choose where to save it:
- Project
- Master Blocks
- Design System
Click Save

Best practices

Keep naming clear (e.g. Footer – Legal v2)
Avoid duplicating similar blocks across categories
Use Master Blocks for anything reused often
Build a Design System if your team creates emails regularly

Where your Blocks are stored

When saving, you’ll see options like:

[Project]: Marketing
[Master Blocks]: Chamaileon
[Design System]: Footer / Content / etc.

This helps you organize and quickly find your blocks later.

How to use a Block

Open the Blocks panel in the editor
Select the category (Project, Master, Design System)
Find your saved block
Drag & drop it into your email

Here is how to use blocks step-by-step with screenshots:

Select the block that you want to reuse

2. Click ''Save Block''

2. Choose where you want to save it. You can save them in your Email's blocks (so you will see those blocks only in the current email), your Folder's blocks (you will be able to access those blocks only from the Folder where you saved them) or your Workspace which means you can access them when creating any email in the given Workspace.

3. When you are creating a new email (or your colleague from the same Workspace) you can reuse those blocks by clicking on Blocks.

You can see your saved sections in your Blocks next to the main elements on the left side of your editor. Choose where you saved your block. If you saved it under a specific folder previously, you can access that block only when creating an email from that folder and then by clicking Blocks, and choosing the folders' blocks.

If you saved the block under ''Workspace blocks'' you will access that block when creating any email in any folder in the Workspace and then choosing ''Workpace blocks''

4. Drag and drop the block into the ''New block''.

Block examples

Company logo block:

→ Every email has to have a company logo; that's how your subscribers recognize who the email is from.

Call to action (CTA buttons)

→ Probably you use just one or two call to action buttons in your email, and using saved blocks will save you the time of recreating them over and over again.
