An algorithm that determins the efficientcy of an email sent by one person to one or more recipients with no body text but just a subject line. AN efficient email will be no higher than 1000. This calculation is as follows

EMEF = ((SU + (REC*SU)) * .75)

Email Efficiency = Subject line count + (Number of recipients * subject line count)/ the percentage of people that read the email
EMEF (Email Efficiency Quotient) = ((SU + (REC*SU)) * .75)

So for your subject line of approximately 50 characters sent to 33 recipients would be (50 + (33*50)) * .75 = 1275.
