remind-email is a tool to send reminds produced by remind command via email.
First of all you need to setup SMTP and some other configurations using
configuration file. See remind-email.conf file in the current source
distribution as an example. remind-email expects the file is to be located at
~/.config/remind-email/remind-email.conf. This behavior can be changed using
-c command-line option.
Next step is to create reminder file(s) in ~/.config/remind-email/reminds
folder. Files location can be changed using -r command-line option. Multiple
files are supported.
Typical scenario is to use cron to call remind-email once per day (e.g. at
midnight) to send an email with reminds for the upcoming day.
Send a reminder email every midnight.
