Hello,
I have a newsletter form already set up on my shopify shop and all I need to do is add a action URL, I would like the action URL to automatically add someones email address into my “new subscribers” list in my klaviyo which then will automatically send them a welcome email however I cannot find anywhere a URL and the URL i did find in subscribe and preferences pages takes me to an error page when I submit an email address
Any help would be appreciated ,
Thanks
