Hi there,

I would like to request that you can implement the feature to allow Alerting Period/Window for Email and Slack alerts too.

In our case, we are IT support company, and we provide monitoring services for our clients. many of our clients only hired us to monitor their servers overnight; while during the daytime they have their own staff to handle this. In this case it's especially helpful and required so we only receive alerts during time periods we're responsible for.
