How to Upload an HTML Email Template

Email messages are great for delivering content to the user on their terms. They are also wonderful tools to re-engage users who may have even uninstalled your app. The Braze dashboard has an email template editor that allows you to create custom-tailored, eye-catching emails and save them for later use in campaigns. You can also create an Email Template using our editor.

Step 1: Navigate to the Email Template Editor

Click on the Templates & Media tab under Engagement in the navigation bar. This will open to the Email Template Gallery.

Step 2: Open the Uploader

Click on the Upload option in the Basic Email Templates box.

Step 3: Upload your Template

Navigate to and upload your template from your computer.

HTML Uploader

Upload Requirements:

Within a single .zip file, you should limit your upload to:

  • A single HTML file (the body of your email),
  • A folder of images that are referenced in the HTML file, and
  • Less than 50 image files.

Generally, the uploaded file must be:

  • Under 5MB and
  • Zipped in a single file.

Solve Upload Email Template Errors

There are several email error messages you can receive when uploading an HTML file for email. You will receive a specific error message describing each of these. Here are a few samples with their recommended fixes:

Error Fix
.zip over 5MB Reduce your file size and try uploading again.
.zip corrupt Inspect your file and try uploading again.
Missing HTML Add HTML file to your .zip file and try uploading again.
Multiple HTML Remove one of the HTML files and try uploading again.
Images over 5MB Reduce the number of images and try uploading again.
Extra Images You may have additional images in your file that are not referenced in your HTML file. This will not cause a fail error, but those extra images will be discarded. If those images were supposed to be referenced in the HTML file, please check its contents, correct any errors, and then try uploading again.
Missing Images If there are images referenced in your HTML file, but those images are not included in the image folder of the .zip file, you will receive a file error. Inspect your file and correct any errors (like misspellings), or add the missing images to your .zip file and try uploading again.

Step 4: Finish and Save Your Template

Click “Save Template” in the bottom right corner of the editor. You can now use this template in any campaign you choose!

Edits made to an existing template will not be reflected in campaigns created using previous versions of that template.

Using Your Templates in API Campaigns

To use your email for an API campaign, you need an email_template_id, which can be found at the bottom of any Email Template created in Braze.
