Hi,
However, in received email, the results are broken and displays as html elements like below:

Jenkins Version: 1.6.46
email-ext plugin: 1.40.5
Tried with below line in DEFAULT_CONTENT
${SCRIPT, template="with_results.groovy"}
Placed groovy file in {Jenkins installation folder}/email-templates/with_results.groovy
any suggestion will be highly helpful.
Thanks,
Guru
