Hi Prashant, Looking at the email implementation in Alertmanager, "to" should be treated exactly as "cc" internally (just optionally supplied through a dedicated YAML field). It's just another header: https://github.com/prometheus/alertmanager/blob/f59460bfd4bf883ca66f4391e7094c0c1794d158/notify/email/email.go#L53-L70
So I would be surprised if the problem is in Alertmanager itself, rather than something in the email pipeline after it. Kind regards, Julius On Fri, Jan 20, 2023 at 1:38 PM Prashant Singh <prashantnit...@gmail.com> wrote: > Dear team, > > prometheus alertmanager CC is not working even as add TO_ and CC_ . > > TO: it is working > CC: it is not working. > > > - name: 'MoniDashboard' > email_configs: > - send_resolved: true > to: 'vinoth.sundaram > headers: > cc: 'PrashantKumar.Singh1' > require_tls: no > > thanks > Prashant > > -- > You received this message because you are subscribed to the Google Groups > "Prometheus Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to prometheus-users+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/prometheus-users/9987573c-ed69-4fb2-94aa-4c37870c540dn%40googlegroups.com > <https://groups.google.com/d/msgid/prometheus-users/9987573c-ed69-4fb2-94aa-4c37870c540dn%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- Julius Volz PromLabs - promlabs.com -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
