You are right that there are many marketing automation systems for sending emails or push notifications. We are focused on product notifications specific to a user's workflow. The API reflects that and, so does the design of the inbox. For example, the API accepts a category for each notification and you can set preferences per category (one of the categories can be marketing). When adding MagicBell to your frontend, you can write a custom click handler and redirect your user to the specific action they need to take on a notification. A lot of the marketing automation tools also lack an in-app inbox that offers a workflow for these notifications (read/unread/delete).
