I receive a newsletter 4 times a year from an organisation that I am subscribed to that organises, assesses and maintains my qualifications. I can’t spot anything in particular that sticks out as AI, but something about the colouring and the art style seems similar to other AI images ive seen.
The text in the image seems to closely match the font of the rest of the newsletter, but I can’t tell.
It would be extremely disappointing if it was, because this particular organisation promotes environmental sustainability.
