Hi there @Jakub ,
Thanks for sharing with the Community.
If there is no symbol next to a person’s contact information, it means they have neither consented nor opted out. These profiles can still receive emails (e.g., an abandoned cart flow email), but exercise caution when contacting them. Also there are certain methods of adding a subscriber that will result in no consent status. For example, subscribers added through certain third-party integrations won’t have a green checkmark next to their email addresses under Channels.
If you are concerned about identifying customers that have expressly opted in, I would suggest to use our Custom Properties, for example, you could create a hidden field on your form that will be passed into Klaviyo, something like “consented”.
I would double check your integration and make sure that consent is being applied in your form’s steps.
Thanks,
Alex
