Getting a lot of spam emails since yesterday (hundreds of em)

Hi everyone,

I need some help. Since yesterday, my inbox has been flooded with spam emails. Someone is spamming hundreds of emails into my inbox. It's making it really hard to use my email at all. I've tried everything I can think of—setting up filters, marking them as spam, creating rules to delete them automatically—but nothing is working. I'm getting really frustrated, can anyone help me with this one? Thanks!

Edit: It was sent from Bombitup app, I added my email to the protection list and no more spam emails.
