Microsoft Flow works great for automating communications, primarily providing the ability to standardize messaging and reduce human error or quality issues.
I leverage my Office 365 skills that are used in an enterprise environment and apply them to my self-proprietorship hobby. I use Microsoft Flow to communicate with my clients (e.g. to confirm payment received) to make things easier for me and provide them with good communication with information specific to them.
One challenge some may experience is the dynamic content for DATE.TIME is not presented to the email receiver in an easy to read format.
An out of the box method without using any code use a Convert Time Zone Action and specify the layout (date.time format).
The outgoing email then needs to be updated to replace the current DATE.TIME (in this case the Ceremony Date) to the Convert Time Zone value.
The end result is an easy to Date.TIME value.
