The Idea of Rasa.io is great and the first look is nice.
But when starting to work with it, there are so many annoying glitches:

1. There is no usefull way to switch between different newsletters. The onliest indication is the graphic shown as a logo, but if you don´t upload a logo (which is used in the newsletter!) there is only an empty space. Ad you can´t even change the newsletter through a dropdown, you have to navigate to "manage newsletter", then select the other newsletter and then you (hopefully) are in the correct newsletter.

2. The language-terms are terrible and can´t be changed. In June they sent out a newsletter with the line "Great news! rasa.io now supports more languages. Languages that rasa.io now supports are English, French, Spanish, German and Portuguese. ". Sadly it´s not true: The languages are not really translated, there is a lot of english wording in the german setting, the terms are terrible and you can´t change them.

3. Articles can´t really be customized. Most annoying: The link of an article can´t be updated. That´s sad, because this way you can´t use an Affiliate-Link for example for an Amazon-Link or anything else. Links ... just are not changable.

4. Switchy is named as an integration. So I tried it with Switchy. I inserted about 10 articles, but only one shows up in switchy. Why that? No Idea. It seems like the Switchy-Integrations works in about one time out of ten.

5. The promised "AI" is not really intelligent. The onliest thing it does is: Tracking how much a subscriber clicked on an article with a certan tag and then sent him more articles with the same tag. That´s it. In my opinion, this is not really "Intelligence" but just some kind of "measuring" and "adjusting".

6. There is nearly no control about which articles are used for a newsletter. I can mark an article as "boost" so the article is forced to be sent to EVERY subscriber, but besides that I don´t even understand how old is an article allowed to be to be sent out.

7. There is only minimal modifications possible at the layout of the newsletter. There are three templates that you can use, on those templates you can define the number of articles, you can sort them differently, you can change colors and logo or add an own HTML-Block. But that´s pretty all you can do.

So while the first look is nice, the usability is really limited. But still ... when all this stuff would be adressed and the AI would more "intelligent" and not only a "tag-measuring-system" it would definitely get great.

However, I keep it. I don´t expect that much from the AI, it´s more like an "article-carusell" then a real AI. And don´t expect too much in the customizations. What I do will be: I set different newsletters up and start them on autopilot, so I can watch an audience growing while waiting and hoping for the ongoing developement. ;)
