I'm experiencing an ongoing issue with a company that bombards us with spam emails. They've been using numerous domains—over 100 unique ones so far—and I've already blocked at least 40 of them. While I can report individual spam instances to the relevant authority, I'm not sure how to convey the full scale of this problem. Has anyone tackled a similar situation and found effective ways to get it under control?

You might want to consider calling them out on LinkedIn! Tag their CEO and head of marketing; it's a bold move but it could draw some attention to their spam tactics.
If the email content is fairly consistent, setting up a transport rule in your mail filter could help. Just make sure it won't catch legitimate emails too!
Have you looked into where these emails are originating from? If they’re using a service like SendGrid or something similar, reporting that could help. It's a good idea to dig into the server details.
Buying a proper mail filter might seem expensive, but it's a proactive way to handle the issue rather than just putting out fires. A specialized tool could save you a lot of hassle in the long run.
Try using Newly Registered Domain (NRD) blocklists. They can help filter out fresh spam domains, although you might encounter some false positives. It's worth checking out options like Spamhaus Zen too; they were super effective for me in the past.
