Although when setting sucuriscan_prettify_mails to disabled the UI reflects the change.
This is because of changeset 1193679 [1] (line 11049).
I tied the core integrity checks alerts with the HTML version of the notifications because one part of the content is a table, I did not have time to implement the text/plain version of that report so I decided to enable the HTML alerts if the user wants to receive core integrity checks alerts.
PS. I may fix that in the future, but will keep it like that for now.

Just writing in the same moment.
Actually the HTML content need html/head/title/body tags also to be valid code.
Please consider adding these.
HTML tags like “html”, “head”, “title”, and even “body” are removed by most webmail render engines because they are irrelevant and (in rare cases) may be used to include unwanted code in the webview. Some people have experienced issues including those tags [1] and others agree with the idea that they are not necessary [2] since most email clients remove them before display the content.
I could include the “html” and “head” tags but they will be filter out before the message is shown in the inbox, the “body” tag will be replaced by a “div”, and the “title” will be ignored.
