Yes - a bad email as the button link is totally unrelated to b4xcode.com. The sort of link you should never click...
So, maybe it's genuine, maybe not. I'm not clicking it!
Hi. They don't seem to be back. It looks like another company (sellix.io) trying to sell us their products again. No information, no updates, no... Doesn't really seem like something too positive, especially for those of us who have previously purchased their products.
Edit: Well, it looks like they are indeed back. Let's hope that this time all doubts will be dispelled.
