How do you create a subscription popup to send the data to Salesforce

Hello,

I’m trying to create a popup with a newsletter subscription, but need to add the email/subscriber in Saelsforce. What’s the best way to do this? Is there an app I could install or will it need to be done outside of Wix with an automation tool?

I’m on Wix studio and don’t have the enterprise version.

Any help much appreciated!
