Helot

Sending personal emails to LOTS of people should not be a pain in the ass. Helot lets you send an email to a CSV list of recipients, based on a Markdown template.

This project was developed entirely in my browser using SourceLair.

Installation

To install Helot just run npm install -g helot.

Usage

Command Line Interface

To send an email to a CSV list of recipients with Helot, run the following command in your terminal:

helot --template=/path/to/template.md --recipients=/path/to/recipients.csv

Command Line Options

The Command Line Interface of Helot can be configured using the following options:

template

The path to the front-matter enabled Markdown template that Helot should parse and render with each recipient's data.

Template example

---
subject: Party next week
---

Hello {{ name }},

Next week we are throwing a party at **Awesome Place**. What about leaving {{ address }} and coming over?

It would be awesome to meet there and have fun.

Looking forward to seeing you.

Cheers,
Paris
