First of all, you need to upload an image and host it on a virtual server.
Then, in the 3rd step of creating your campaign, you can use the HTML editor. To insert an image, simply click on “Image” and then choose one of the options:
- Drag an image from your computer into the system, select the image path inside your computer,
- Insert a link to access this image (if it is already hosted on a virtual server).
