Integrate with SendInBlue

Hello! I use SendInBlue for my newsletter and would like to use your plugin with it since my theme, Novelty by Restored316, utilizes it. Restored316 provides setup instructions for services like MailChimp, but not SendInBlue. Can I just follow the steps for MailChimp (finding the embed code and copying the form’s action URL into the field in the widget) and it will work? I wasn’t sure if your plugin only works with specific Newsletter services. Please advise. SendInBlue isn’t offering any support.
