Hi Sally,

Here is the Source value reference for all $source numbers.

It seems that -50 for the property $source equals Shopify.

It’d be great to understand where this -50 is being implemented. Is it during the checkout process, or perhaps through a different sign-up mechanism, separate from your usual pop-up, like the footer?

Additionally, I have a couple of queries regarding your subscriber management:

1. Do you consolidate all subscribers into a single list (default called Newsletter), or do you maintain multiple lists segmented by different sign-up forms?
2. Is there a filtering system in place that excludes customers who have completed a purchase from receiving the Welcome flow? My concern is that if the -50 tag is applied post-consent in the Checkout process, those customers might not be the intended recipients of the Welcome flow.

:)

Thanks so much. I do consolidate all subscribers into a single list so sound like I might want to create a second list. Yes, clients that have completed a purchase do not receive my welcome flow. And, I have verified that -50 tag is not applied during checkout. This is such a mystery as I cannot figure out where in shopify the sign up is occuring. Thank you for your help.

Hey @sally,

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 :)
