I’ve done Paper.li newsletters for clients. I always tell them to get the paid version so they can customize their paper with their own banner, ads, and content, as well as the curated content and images that Paper.li pulls in for you. It takes a bit of time to train the software to curate the right articles for you, or you can only content you’ve curated. It makes a really professional looking paper that can be sent out through your email service.
