Mailterlite connection to Teachable platform

Hello,
I'm looking for someone to support with setting up an API connection (potentially using Zapier) to link my mailing list software (Mailerlite) to my online courses platform (Teachable), so that when students complete the email sign up form embedded within a specific landing page in Teachable, it will automatically add them to my mailing list within Mailerlite but also grouped by the specific course that they have expressed an interest in. I am aiming to establish pre-sales interest from customers for courses that are still in development, therefore gathering email sign ups from people expressing an interest where it shows me exactly which course it is they are interested in is vital.
