The benefit of utilising a custom 'From address' for content notifications is that it greatly aids in overall adoption and engagement of your released content.

It achieves a positive reception from your end users. Having been presented with a course notification from a familiar domain, they will deem the notification to have come directly from your organisation. This has proven to greatly improve the overall adoption of released content, as end users are less likely to perceive the notification as suspicious.

With higher adoption rates for your released content, you will be in a better position to mitigate the risks posed to the organisation, further raise awareness among colleagues and improve the company's culture.
