Email Service

Create simple but beautiful email templates and send email using REST. The idea is to keep things simple, without having to write complicated HTML or CSS files. A simple JSON object is all you need to define a new template! Integrates seamlessly with Mail Gun.

Features

RESTful
Responsive HTML
Dynamic Templates
Global Variables
Conditional Expressions
Internationalization
Fine-grained Permissions

Setup

A configuration file is required to let the service connect to the MongoDB database and the RailGun API. Create a file in the same folder as the .jar-file called application.properties with the following content:

# MongoDB Settings
spring.data.mongodb.database = emaildb
spring.data.mongodb.host     = localhost
spring.data.mongodb.port     = 27017

# MailChimp Settings
mailgun.apiKey =
mailgun.domain =

To set up the initial user (with all permissions set), run the jar file like this:

java -jar email-service.jar --init -u admin -p password

The user will be saved in the MongoDB database so it doesn't have to be created each time.

API Examples

Here are some examples on how to use the service. All commands require a valid API Key to be specified using Basic Authentication.

Set Option

Define global variables to be used in all templates:

POST /options/{name}

{
    "value" : "..."
}

Create a Template

Create a new template with support for two languages:

POST /templates

{
    "name"     : "registerConfirm",
    "sender"   : "Membaza",
    "email"    : "noreply@membaza.com",
    "replyTo"  : "info@membaza.com",
    "languages": {
        "en": {
            "_subject": "${firstname?Hi, {firstname}!|Hello!}!",
            "p1"      : "Welcome to ${sitename}!",
            "p2"      : "Did you get this by mistake?",
            "create"  : "Create Account",
            "report"  : "Let us know!"
        },
        "sv": {
            "_subject": "${firstname?Hej, {firstname}!|Hejsan!}!",
            "p1"      : "Välkommen till ${sitename}!",
            "p2"      : "Fick du detta av misstag?",
            "create"  : "Skapa Konto",
            "report"  : "Anmäl detta!"
        }
    },
    "content": [
        {"type": "title",  "value": "${subject}"},
        {"type": "text",   "value": "${p1}"},
        {"type": "button", "value": "${create}", "href": "${url.verify}"},
        {"type": "text",   "value": "${p2} <a href=\"${report}\">${url.cancel}</a>"},
    ]
}
