gmt 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 Go and used mainly on linux systems like Arch Linux, Fedora and Ubuntu.
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.
$ go build
$ ./gmt -sample-config > /tmp/sc.ini
$ ./gmt -sample-template > /tmp/st.eml
$ ./gmt -dry-run -config-path /tmp/sc.ini -template-path /tmp/st.eml
