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.
