Best what you can do is send a new subscriber to your email marketing product and include variables that you need for sending personalized emails. Sometimes it is just a name, but in our case we send about 30 different fields that tell a complete story about that user. When one or more of those fields get updated, we update the user in our email marketing as well.

In our email marketing product we have all kinds of automations. This means that “heavy” data operations happen outside of Bubble.
