Here is how you can send emails being collected from Justuno to two different email lists within your email marketing application
Step 1: Create a email collection using a form builder within your email marketing application from list "A". Here is a document on how to add in a form.
Step 2: Finish editing the design and skip to step 3: Integrations. Click on the integration you are using and find the second list you would like to send an email to. Here is a link to our integrations list page.
Step 3: Hit save and publish. Now the emails from List A are being pushed from the form integration, and at the same time are being sent to List B from the integrations (step 3) set up!
