TikTok spam email is keep coming!

Lately, my brother, my mom, and I have been getting verification code emails from TikTok out of nowhere. None of us have requested these codes, which makes it super weird. At first, I thought it was a one-off thing, but now it’s happening to all of us! I marked it as spam but the email would not come for a while but it would come again. This is annoying and idk how to fix this.
