For service trialing purposes we offer only default newsletter template. It doesn't allow for customization. Also, we've built our whole service around machine learning and smart content recommendation engine. While it may sound weird and complicated, it actually aimed at simplicity — it takes the guesswork out of your process of content selection. Makes your day easier and frees us space for other important things.
By monitoring your audience behavior our system knows what article will be the most relevant and interesting to each of your readers.
If you want to influence the content selection process, you can set up your CMS to feed particular stories to RSS that you've provided to Newzmate upon integration and our system will use them to build personalized newsletters.
