New Shopify design themes do not support Action URLs. We suggest integrating your footer signup form manually.
Soundest, as an Email Marketing and Ecommerce platform, uses an embedded HTML form to collect email signups for your newsletter campaigns. Many Shopify themes provide the same structure that Soundest uses (except the new themes, they do not have the option to add the action url), and you only need to enter your unique Landing Page Link to enable your customers to submit their email addresses. You can do this on the Customize theme page of your Shopify admin. But first you will need your Soundest Landing Page Link.
Where can I get my Soundest Landing Page Link?
Please go to Subscribers > Forms > CREATE FORM > Landing page
Now, please go to your Shopify Admin and follow the instructions:
1. Click on Online Store - Themes - Customize Theme:
2. Select Sections - Footer:
3. Paste Soundest Landing page Link in the field marked as MailChimp form action URL:
4. Click SAVE
Your Signup form in the footer of your Shopify Theme is now integrated with Soundest!
