color text notifications

[RDMaroto]

Good morning
I'd like to know if it is possible to modify the color of the text of notifications by email of nagios.

For example a phrase appears red, or if it is a recovery in green.
Is possible?
Thank you
Regards

You might be able to wrap some HTML <span> tags around the words in question and style them however you like, but the rendering would depend on your email client. You can just alter the notify-*-by-email commands to add in the HTML, making sure to escape characters where needed.
