Greetings user_tmvi2
Appreciate you reaching out. Thank you so much for looping us in on this issue. The user might have flagged the account for spam. But you are easily able to reach out to our security team about this situation. I would advise touching base with the user outside a blast based email marketing process to loop them in, and ask if they accidentally flagged the email. I included the contact for our security team here below.
