I have many recent subscribers with the source -50. They are added to my subscriber list, but they do not enter my welcome flow becuase they do not sign up through my newsletter sign up. I think that these are not valid subscribers. How do they sign up and what is the best way to purge them from my subscriber list?
Profiles with Source -50

Hey
After further investigation, if a profile took any of these below actions, they could be synced with the -50 source value.
• If the profile placed an order through your website,
• If a customer was tracked via a Shopify form,
• If a customer started checkout, and ticked the checkbox on the checkout page for consenting to marketing - whether they opted in or not,
• If a customer submitted a Klaviyo form on Shopify that had no $source value assigned to it, they may come across with a value of -50 as well in some cases, or they may just have a blank source value. That could be a quiz, or any other app that collects emails!
How about you create a segment like this:

And review the profiles in it:
1. Where do they sign up? Is it at Checkout? Or after they land on your website?
2. Do they receive the Welcome emails?
Let me know if that helps,
🚨🚨🚨 Please do not move to multiple lists, as it’ll probably make your life more complicated. Stick to one main list please :)
