Hi I am trying to import a mailing list, at first it was around 1200 subscribers, I tried uploading then it says its failed "This list has addresses that may cause high bounce rates and spam reports. Remove any fake, invalid, and improperly formatted addresses, and ensure you have consent to mail everyone on your list." then I user Bouncer, to remove all undeliverable, risky or spam emails. I uploaded the new CSV and its still the same.
Please help i do not want to manually add one each but I will if I have to.
