Command line Personalized Email Sending with Mailgun from CSV file

This simple program can handle CSV files for personalized email sending using Mailgun API. It uses template language Mustache for both HTML and Plain text templates.

The reason for this command line interface is fast preparation of Email Template Contents with exported CSV list.

Edit the config file under data/config.json, prepare domain name and api key from Mailgun, change subject and from.

{
	"domain_name": "domainname",
	"api_key": "appkey",
	"subject": "this is my subject",
	"from": "mymail <mymail@mymail.com>",
	"html_template":"templates/simple-template.html",
	"text_template":"templates/simple-template.txt",
	"test":true
}

Modify Exampl Excel file under data/example.csv.

• CSV file must have headers as first line
• There must be at least 1 field named: email in the headers
• Other header names are used as Mustache placeholders in the template

myemail@mymail.com,Ashley,3/12/18
myemail@mymail.com,igor2,3/12/18

Plain/Text template example

Hi {{name}},

Sometimes you just want to send a simple HTML email with a simple design and clear call to action. This is it.

This is a really simple email template. Its sole purpose is to get the recipient to click the button with no distractions.

Good luck! The date is {{date}}.
