Yes and no.
We have an 'email' scheduled task (cron) plugin, which can do that.
The tricky part is getting it to run at the right time. The problem being that J! doesn't have a scheduler, as "real" scheduling is an OS dependent task. We fake it, by having our "Fabrik Schedules Task" system plugin run on every (front end) page load, as the last thing J! runs ("onAfterRender"). We then check in our fabrik_cron table to see if there's any tasks to run. But of course, that relies on your site being loaded by someone. If nobody hits your front end till (say) 11am, then the task won't run till then.
The best way round this is to set up your own 'cron' task in your OS. So in Linux, a 'cron' job. Which you can either do by hand on a command line, or if you have CPanel, there's usually a way of setting up a scheduled task there. Or there are third party web sites that let you set up tasks. And your task should be a "wget
http://your.site/index.php?fabrik_cron=YOURSECRET". The wget commad is a UN*X command line to fetch a web page.
Then in your email cron plugin, one of the option is "query string secret", which you should set to "YOURSECRET" (well, not literally, but you know what I mean ... just pick a random secret word). What that does is says "only bother running this task if the page load contains this secret word.
