We have had the same problem with Microsoft where our marketing department is effectively DDoSing our service by sending out links to 50k+ users.

We would get spikes of thousands of requests per second from Microsoft IP addresses, which after some googling were linked to their threat detection.

Threat detection is becoming essential because of ransomware phishing and alikes, protection from click tracking is good too.

Just send email in tranches.

If the marketing department is sending too many e-mails for the web server to handle, then the volume is probably out of proportion to the company and what they are doing is probably just spam.

I agree, I'm not blaming Microsoft here, and it is our problem to solve (the service should handle the traffic, and/or the emails should be staggered over time)
