Now, this concept is nothing new. Existing Reverse ETL solutions already provide this capability, but the problem is that the feature is available only in their expensive "enterprise" package. This makes it difficult for an average marketer or product manager to leverage this capability.
Today, we are excited to announce that we are making our Audience Builder available as a standalone product - Castled Audiences. With Audiences, you can create custom user segments in your warehouse and send them to a destination of your choice. Also, this feature is available in our Starter package - no hidden conditions applicable. The cost is the same if you are sending it to 1 destination or 20. Here is a demo:

Feel free to email me at [email protected], if you want to give it a try. If you do not find the destination you are looking for - Let us know and we will get it added within a day or two.
