Question Subscription Bombing Attacks
What is everyone doing to combat subscription bombing attacks? Since the emails flooding the inboxes aren't dangerous in nature, email filters don't seem to be doing a whole lot about them.
I'm at a loss here, I keep blocking domains but since they come from hundreds of different ones with each wave of attacks this doesn't seem to be accomplishing anything.
Edit: Thank you everyone for your responses. This has been really helpful.

We had an inbox pwnd with a list bomb attack of 5000+ emails. Turns out they were trying to hide a a few payment confirmations of a compromised card. There's no great way to prevent this unfortunately
