[Koha] Where can we find e-mail notices ready to be sent

[vanda koha]

Hi everybody,

I have properly set the circulation rules, the item circulation alerts,
defined e-mail notices and set notice/status triggers for overdue items.
But now I have a doubt: where can I find the list of all notices (specially
overdue notices, but also renewals, holds ready to be picked up, etc) that
are ready to be sent to our users? I know some users have overdues, but I
don't know where to look for the notices. Can anyone help me, please?
Many thanks,

Vanda
