Hey @Adorn Jewellery
Thanks for reaching out for help with your subscriber list. Thanks @Bobi N. for jumping in to help.
While Bobi is correct, you will need to update their consent status in order to meet Klaviyo’s terms of use, as we don’t allow marketing to be sent without consent. Sending to a lot of profiles without consent can send a red flag to our compliance team and could negatively impact your account. I would recommend uploading consent status with a CSV file to all the profiles that have given their consent. This will make sure your account stays compliant and that you are only sending messages to those customers who want to hear from your brand.
Hope this helps!
