Re: SVN server email notification function (SMTP) and How To configure it

Another suggestion: https://github.com/qazwart/SVN-Watcher-Hook

I've used a custom version of that (perl) hook script. It allows your
users to control their own "watch file" (in the svn repository
itself), which is a simple config file containing patterns etc. for
which they want to receive post-commit mails.

It's not a GUI, but it's great that users can edit their own watch
file (with a very simple syntax), so they don't have to bother a
sysadmin to customize their notifications.
