The Challenges Developers Face with Email & Page Builders

Limitations of traditional WYSIWYG builders

Many developers find that traditional WYSIWYG editors lack precision. Because they often generate inconsistent or unpredictable output, making it hard to maintain brand consistency or control the final rendering. 

Common pain points

• Rigid templates: Pre-built templates are often too restrictive. Developers and designers want the flexibility to create custom components or modify layouts freely without being locked into rigid structures. 

• Lack of customization: Many builders limit developers’ ability to inject custom HTML, CSS, JavaScript, and dynamic content. 

• Cross-client compatibility: Developers worry about email rendering issues across Outlook, Gmail, Apple Mail, and other Email Service Providers (ESPs).

• Performance concerns: Some builders generate slow-loading emails or pages due to excessive styling and scripts.

The need for a developer-friendly low-code solution

Given these challenges, developers need a white-label solution that pairs the intuitive experience of a WYSIWYG editor with the flexibility to build custom tools, enforce brand consistency, and integrate seamlessly into their existing stack. 

Here are some key components that form the core of a developer-friendly builder:

• Complete customization options without restrictive templates.

• Optimized, clean code output to prevent performance issues.

• Seamless integrations with existing tools and workflows.

• Cross-platform compatibility to ensure consistent rendering across all devices and email clients.

How to Get Started With Unlayer’s No-Code Builder?

Integrating Unlayer is quick and efficient. Follow these steps to embed the no-code email/page builder into your application.

1️⃣ Add JavaScript library (2-3 minutes)

• Include Unlayer’s script in your web app:

• For React, Angular, or Vue, install the respective npm package.

2️⃣ Add editor container (1-2 minutes)

• The Unlayer editor needs a container element on your page. Insert a blank <div> where the editor will be displayed:

• Recommended size for the container: 1024px wide, 700px high.

3️⃣ Initialize the editor (3-5 minutes)

• Initialize the editor inside the container you just created by passing its id and configuration options.

• Retrieve the Project ID from the Developer Console under Project > Settings.

4️⃣ Customize configuration (5-10 minutes)

Configure settings such as:

• Locale (language support)

• Appearance (branding & themes)

• User Info (id, name, email through merge tags)

• Custom Tools, Blocks, Fonts, CSS & JS

5️⃣ Enable multiple instances (Optional) (3-7 minutes)

• If using multiple builders on a single page:

6️⃣ Deploy to production (5 minutes)

To enable premium features and secure your builder in production:

• Log in to the Developer Console and navigate to your project.

• Retrieve the Project ID from Project > Settings and pass it in unlayer.init().

• Add Allowed Domains to ensure the builder works only on specified domains:

  • Go to Project > Settings > Deployment.

  • Add your allowed domains under the “Allowed Domain(s)” section.

7️⃣ Connect the API (5-10 minutes)

Unlayer’s builder provides APIs to load, save, and even auto-save designs in your host application. Learn more about this here.

Load & save designs

• Use unlayer.loadDesign() to preload saved templates:
