The HTML custom code editor allows you to upload your own HTML file to design fully customized emails. It’s ideal if you already have an email coded by an agency, built outside of Brevo.  

Before you start

• Some email clients do not support all HTML content as email HTML isn't as developed as web HTML. To avoid issues with your code in the HTML editor and block, check our dedicated article Limitations when using HTML for your email designs.
• We recommend adding images using the <img src= [...] > attribute rather than embedding them directly in your email.
  💡 Good to know

  If you do need to embed an image, insert it first and then enable the dedicated option in your campaign’s Additional settings. Keep in mind that embedded content counts toward your email size limit and can only use up to 1 MB of the 5 MB maximum.

🧑‍💻 Access the HTML custom code editor 

To start designing with the HTML editor:

1. Create an email campaign or email template and set it up. 
2. Click Start designing or Add content to open the editor selection menu.
3. Click Start from scratch > Simple editor.
   

The HTML editor opens, where you can upload your own HTML file to design your email! Next time, you will be able to select your previously created emails from the Your emails category. Use your emails designed with the HTML email editor in your email campaigns, automations, and conversations! 

</> Upload an HTML file 

Once you have opened the HTML editor: 

1. Open the HTML file to view the code. You can either: 
   • Open the file in a text editor if you have one, or
   • Open the file in your browser, click right on the page and select View Page Source. 
     
2. Select the entire code and copy it.
3. From your email creation, access the HTML custom code editor.
4. Paste the code in the HTML custom code editor.
5. (Optional) Click Actions > Save as template to save your HTML design as a template and reuse it in future campaigns or automations. Name it to easily find and recognize it in your email templates list and click Save as template. 
   
   ❗️ Important

   Any changes you make to your design after saving it as a template will not be reflected in the template.
6. Click Save & quit.

You can now preview and test your email to see if it works!
