Ask HN: Is your email inbox also filled with Zendesk reply spam?

This is happening to me too.

I suspect the recipient email address they're using (which I don't share widely) might have been exposed in one of Discord's recent support breaches, because I can't work out where else they could've got it from.

I'm using Proton Mail, so I set up a Sieve filter [1]. I'm doing this because this email address isn't used for anything even remotely related to Zendesk. I mostly use a separate custom domain address for everything.

I'm on Gmail and getting flooded with it... About half of it is going to the Spam folder, which makes me wonder how it decides which of them are likely spam, since they're all very similar content-wise.

Yes, sadly they are legitimate emails so its hard to block them. The problem seems to be on zendesk side where they are accepting any email as the source of the ticket and simply replying to that email with the contents of the ticket.

Apparently they are well aware of this problem since at least last year:

https://support.zendesk.com/hc/en-us/articles/9833274501786-...

Currently I'm getting a new “request received” or other new-support-ticket email every minute or two, from all sorts of different ZenDesk customers. It seems like I'm not the only one, and it's not limited to one particular email provider: someone I know using Gmail is getting this, whereas I'm using a well-known commercial email host with a custom domain.

Yes, about 30 emails so far in the past 20 minutes.

EDIT: After checking spam, it's more like 150

Yes. At this point zendesk is a spam-as-a-service platform.
