Hi @AronMurch,
The green check mark consent status is only updated when someone signs up using a Klaviyo signup form, or when they use a Shopify form or accept marketing in checkout and the Accepts Marketing property is set to true. Third party forms use Klaviyo's API to subscribe profiles to lists, and those do not receive an updated consent status as you would see for profiles using Klaviyo forms. This is expected behavior with third party forms , and if they have signed up that can be interpreted as their consent to receive marketing. Generally you can use a few different pieces of information to determine if someone is a valid profile for you to email. If they signed up using one of your signup forms and are in your list, or if they have accepted marketing in checkout and have the Accepts Marketing property set to True, or if they're in your list, signed up using a Klaviyo form and have the green check mark I would feel confident that they've given appropriate consent. If they have the red X, they are suppressed and cannot be emailed. If they have no consent status, are not in any of your lists, or if they have the Accepts Marketing property set to False (and aren't in your list), I wouldn't recommend including them in a Newsletter campaign. Related doc: Profiles without a Consent Status
The consent status checkmark is there just to inform & indicate to the users in the account whether the profile has properly consented to email marketing but not having this checkmark will not cause any issues or have any negative impact on your account's deliverability or its standing with Klaviyo when it comes to sending them an email.
I will make a note to our docs team and make a request regarding that article to include more details.
Hope this made sense,
Alex
