Hi Team.
As per which option used in Setup IFS connect ( for MAIL_SENDER1)

Email output generated from event action NOTIFY_CHECKLIST_RESP_EMPLOYEE will be changed as below;
Result 1 ( text/html )

Result 2 ( text/Plain)

As you can observe above, one option does not make Message_string work properly and other option does not make “Click Here” link work.
So Would there be anyway both could be worked as same time ?
( Line breakers option does not work on MESSAGE_STRING)
