Yes, it was in the panic mode. We kicked off the bulk mail Azure Communication Service. But some how the code got stuck and became unresponsive due to a temp outage on Azure, but it went into their queue. We waited until 20-30 mins but did not receive any blast emails thus panicked and tried to send it manually via our mail provider i.e. proton and picked the wrong send from address and CC'd. Shame on us! We will be more mindful of this, a big lesson learnt.
