This morning our sendgrid account (with 4 years of good standing paying $x,000 a year) is showing as suspended. No change in spam or bounce rates (both tiny). No communication from them.<p>Their support page is showing as 'email only' due to 'volume'.<p>We have customers with events today that are severely impacted by this. I hate to use HN as a support channel but they don't provide a lot of choices.
Fortunately their support was able to get back within a couple of hours (much faster than the 3-5 days listed on the page) and reactivated the account.<p>Looks like a mis-fire of the automated suspension system which seems to be a huge problem of these types of systems when you are on the receiving end.
I'm afraid HN can't help on that.<p>But it does recall me a concern we had when we moved our email service to SendGrid. If there's something wrong with the third party, we're doomed... :/
