Can't you just send an email?

I think our most frequent use case would be trying to keep our alerts in sync. For example, if we close something Siemplify we'd like to automatically dismiss it in PagerDuty

ok, my bad

i think you should still be able to do that by email though right? we have pagerduty and have only so far set up triggering a pagerduty alert but i think you can also reply to a pagerduty alert to close it?

Seems this can be done via email

Thanks guys! I'll take a closer look at how we can do this with email
