I had a large email list added a while back from some giveaway. I had spent the past few months really cleaning up the list and had deleted a load of spammy account and just other unengaged profiles. Yesterday i noticed all these profiles added back into my Klaviyo. I am not sure how their data can be recovered as i had deleted them, not just suppressed them. I tried creating a list based on people not in my other engaged lists etc, however it did not register any profiles? I am really unsure how i am supposed to get rid of these profiles and do not want to pay for a load of profiles i have already deleted.
Please help
