Hi @brewcrew,
If you're looking to create a Signup for customers to enter your Klaviyo Account, the best method is to Create a Signup Form to directly port into your Klaviyo list on your specific website. That being said, creating a Form won't create a new website page. What I've seen in similar situations is that brands create a new page on their eCom provider, and insert only an Embedded Signup Form on the page.
What's particularly helpful about this is that our Signup Forms allow you to port emails to a specified List, so you can keep this group totally separated from your other Profiles and Segments.
Please note, Klaviyo Accounts only connect with one URL. If you want the emails directly into your account, I would recommend hosting the page on your Shopify, since it looks like the integration is successfully enabled. If hosted elsewhere, you may need to repeatedly manually upload a the list of entries into your account.
In case it's helpful, I also wanted to attach a few Help Center articles we have on giveaways and sweepstakes below:
Hope this helped!
