I started a thread a few years ago and wanted to get back to it - it's something that I think needs to be remedied within the SolarWinds Orion Alerting Engine. I'm placing it in NPM because SolarWinds Orion Core (Alerting, Reporting, Syslogs/Traps, Event Log, etc.) doesn't have a specific Feature Request section.
This is the crux of it:
Feature Request: Please include just a checkbox or something in the Configure Action: Send an Email/Page to allow me to enable/disable the auto-replacement of a end of line characters with a <br />.
