How to send API emails to Contact List


Hi! I'm trying to send emails to a contact list (a dynamic list) using any API method. Single-send looks like it only accetps one email address. SMTP could be, but I need to specify each email address, right? Or there is a way to indicate the contact list's name as the destination?

The use case is that I need to send an email with some content generated in my system (it can be an email created in Hubspot and filled with custom properties or I can generate the whole email on my side) and then use the contact list living in Hubspot to send the email. I want to trigger the send from my system.

Thanks in advance!
