What percentage of households are reached via email?

I was recently asked, “What percentage of households can be reached by the district when we send out an email?”

Answer:  91.97%

Q1.  How is this calculated?
A1.  We query Infinite Campus and look at each individual student – do they have at least one guardian who has an email address in the system?  If a student has at least one guardian with an email address, then it is counted as a yes, we can reach the household for that child via email.

Q2.  How does the data compare across our schools?
A2.
