Using Base64 images in HTML email templates

To hardcode an image into an email template written in HTML, use Base64. Converting an image to Base64 makes the image into a long string of text.

  1. Use an image converting tool (such as this one by Atatus) to convert your image to Base64.
  2. Using image <img> and alt text alt tags, copy and paste the Base64 string into your template like this:

<img alt="ALT TEXT HERE" src="PASTE HERE"/>


The alt text is optional, but it is recommended in case your image doesn't load for any reason.
