HI,
does your user wants to send out newsletter as one image or do you need to create the layout of the newsletter content to look similar to the layout seen in the images?
If you need the first, then I guess you will have to create that image in some other application and ad it in the image block in AcyMailing
If you need the second then you can use it by clever arrangement of content blocks, using content columns blocks
Regards,
Igor
