Problem

Unable to upload the ZIP file to the HTML template in the Email campaign, resulting in the following error message: Oh snap! Zip upload failed. Please contact our support team.

​
Prerequisites

Ensure the ZIP file meets the following requirements during the upload process:
  • Ensure that the file size is under 5 MB.
  • Use a file name without the *, /, , &, ~, or ” characters.
  • Include only one HTML file with inlined CSS.
  • Use JPG, JPEG, PNG, or GIF formats for images.
  • Ensure the image paths match the ZIP folder structure, including case sensitivity.

​
Explanation

  • HTML is a markup language where minor code issues do not usually impact rendering on the localhost or server.
  • The HTML editor accepts code without errors, so the uploaded code should be error-free.

​
Instructions

  • Ensure that both opening and closing tags exist because they are essential for proper functionality. For example, the correct code must look as follows: 
    <div><p> contents  </p></div>
  • Ensure that all created classes have a corresponding closing tag. For example, the correct code must look as follows: 
    .myclass{
color:"red"
}
.mysecondclass{
color:"blue"
}
You can perform checks on the utilized CSS.
