mmt is a simple utility that allows the automated sending of emails using a configuration file and a template for the email body.
It was written in Elixir and used mainly on linux systems like Arch Linux, Fedora and Ubuntu.
Running mmt requires a running mail transfer agent (MTA) e.g. postfix and the GNU mailutils software (Arch Linux: pacman -S mailutils, Ubuntu: apt-get install mailutils). For Fedora etc. you are all set since mailx is installed by default.
The easiest way to use the tool is to generate a sample configuration (--sample-config) and a template file (--sample-template) and take it from there.
$ ./mmt --help
Send emails in bulk based on a template and a config file containing
the email body and recipient names/addresses respectively.
--help print this help
--config-path path to the config file
--dry-run print commands that would be executed, but do not
execute them
--subject email subject
--template-path path to the template file
--sample-config prints a sample config file to stdout
--sample-template prints a sample template file to stdout
