# Quartz-Mailer

[![Build Status](https://travis-ci.org/amberframework/quartz-mailer.svg?branch=master)](https://travis-ci.org/amberframework/quartz-mailer)

A library to send emails from your Crystal application.

## Installation

Add this to your application's `shard.yml`:

```yaml
dependencies:
  quartz_mailer:
    github: amberframework/quartz-mailer
```

## Usage

```crystal
require "quartz_mailer"
```

The mailer has the ability to set the `from`, `to`, `cc`, `bcc`, and `subject` as well as both `text` and `html` body formats. You can also add custom headers using `header` method.

A `render` helper provides friendly markup rendering with [jeromegn/kilt](https://github.com/jeromegn/kilt).

```crystal
class WelcomeMailer < Quartz::Composer
  def sender
    address email: "info@amberframework.org", name: "Amber"
  end

  def initialize(name : String, email : String)
    to name: name, email: email # Can be called multiple times to add more recipients
    subject "Welcome to Amber"
    header "X-Custom-Header", "value" # Can be called multiple times to add more custom headers
    text render("mailers/welcome_mailer.text.ecr")
    html render("mailers/welcome_mailer.html.slang", "mailer-layout.html.slang")
  end
end
```

To deliver a new email:
```crystal
WelcomeMailer.new(name, email).deliver
```

To remove a recipient:
```crystal
remove_to_recipient email: "to@foobar.com"
remove_cc_recipient email: "cc@foobar.com"
remove_bcc_recipient email: "bcc@foobar.com"
```

## Multiple Recipient Example:

```crystal
class MultipleRecipientMailer < Quartz::Composer
  def sender
    address email: "info@amberframework.org", name: "Amber"
  end

  def initialize(to_emails : Array(String), cc_emails = [] of String, bcc_emails = [] of String, headers = {} of String => String)
    to_emails.each do |email|
      to email
    end

    cc_emails.each do |email|
      cc email
    end

    bcc_emails.each do |email|
      bcc email
    end

    headers.each do |name, value|
      header name, value
    end

    subject "Welcome to Amber"
    text render("mailers/welcome_mailer.text.ecr")
    html render("mailers/welcome_mailer.html.slang", "mailer-layout.html.slang")
  end
end

MultipleRecipientMailer.new(email_addrs, cc_email_addrs, bcc_email_addrs).deliver
```
