Hey Aerial, nice to meet you. This can be tricky to understand for sure, maybe I can help
To answer your question: Yes, profiles who subscribe from your embedded form or pop-up form will go to ‘List A’ as long as both of the forms are linked to ‘List A.’
If you’d like a better understanding of why there’s a difference in profiles in the segment you created, here’s a quick rundown of ‘Subscribed to List’ and ‘Accepts Marketing’.
Subscribed to List
The Subscribed to List metric is added to a Klaviyo profile if the profile subscribed to a list via a Klaviyo signup form, through QuickAdd, or with the V2 List API’s subscribe endpoint.
Accepts Marketing
“Accepts Marketing” is a separate, Shopify-specific property that is added to a Klaviyo profile when a customer checks, or does not check, the Accepts Marketing box at checkout.
Putting It Together
Seeing as the ‘Accepts Marketing’ property exists independently from ‘Subscribed to List’, the additional profiles you’re seeing in the segment could be subscribers that were gathered at checkout who did not complete any of the actions that would warrant the ‘Subscribed to List’ metric to be added to their Klaviyo profile.
Here are some recommendations moving forward:
Hope this helps!
All the best,

It’s also worth noting the following for future reference:
User A, subscribes via the Shopify Checkout and is added to the Newsletter List (via the standard process), their profile will be marked with the ‘Accepts Marketing = True’ custom property.
If User A goes on to unsubcribe via a Klaviyo email, they will be removed from the Newsletter list but the ‘Accepts Marketing = True’ custom property will not be updated.
What we recommend for our all customers is that all data is added to a single list (regardless of source) and custom properties are used for segmentation. Then you build the segments whilst including this list. So for example if I wanted to find all customers who have purchased the blue shirt in the last 30 days and were contactable via email I would build the segment as follows:
Is in ‘Newsletter’
Is not supressed
Placed order where item = blue shirt in the last 30 days
