Ask HN: My sendgrid account sends spam. I can't stop it

3 pointstobltobs2 comments

I already removed all API keys, Blocked all IPs, changed passwords but still logs shows that there are still spam emails are send, lots of them. Can't reach support via email or twitter. What am I supposed to do? Does anybody have a contact to a sendgrid guy?

Is it possible they have broken your DKIM key? If so they can send email signed as coming from you without needing your Sendgrid credentials. Remove all your Sendgrid DNS records, and make sure you DKIM key is using 2048 bit modulus or higher.

They're part of Twilio, maybe the Twilio support has a fast track or can forward a request to a sendgrid guy or girl.
