Primary Outcomes
Primary Outcomes (end points)
The response rate, response time, and cordiality of responses, by political party.
Primary Outcomes (explanation)
The response rate will be the proportion of emails that are answered. Response time will be average time to response, conditional on response. Cordiality is a dummy indicator for whether the response includes a salutation such as "Dear... ".

Secondary Outcomes (explanation)
Experimental Design
Experimental Design
Each recipient is randomised to receive a different treatment or control condition.
Experimental Design Details
Each local politician is randomly assigned to receive an email from one of 6 treatment names (3 religions, 2 sexes) and one of two email scripts. In effect the Jewish and Muslim -sounding names are treatments and a Christian-sounding name is the control group. One of the email scripts in non-descript, whereas the other explicitly mentions the emailer's religion.
Randomization Method
In office by computer
Randomization Unit
Individual politician
Was the treatment clustered?
