A Postmark adapter for the Bamboo email library.

Installation

The package can be installed by adding :bamboo_postmark to your list of dependencies in mix.exs:

def deps do
  # Get from hex
  [
    {:bamboo_postmark, "~> 1.0"}
  ]

  # Or use the latest from master
  [
    {:bamboo_postmark, github: "pablo-co/bamboo_postmark"}
  ]
end

Add your Postmark API key to your config. You can find this key as Server API token under the Credentials tab in each Postmark server.

# In your configuration file:
#  * General configuration: config/config.exs
#  * Recommended production only: config/prod.exs

config :my_app, MyApp.Mailer,
      adapter: Bamboo.PostmarkAdapter,
      api_key: "my_api_key"
      # Or if you want to use an ENV variable:
      # api_key: {:system, "POSTMARK_API_KEY"}

Follow Bamboo Getting Started Guide.

Using templates

The Postmark adapter provides a helper module for setting the template of an email.

defmodule MyApp.Mail do
  import Bamboo.PostmarkHelper

  def some_email do
    email
    |> template("id_of_template",
                %{name: "John Doe", confirm_link: "http://www.link.com"})
  end
end

Exception Warning

Postmark templates include a subject, HTML body and text body and thus these shouldn't be included in the email as they will raise an API exception.

email
|> template("id", %{value: "Some value"})
|> subject("Will raise exception")
|> html_body("<p>Will raise exception</p>")
|> text_body("Will raise exception")

Tagging emails

The Postmark adapter provides a helper module for tagging emails.

defmodule MyApp.Mail do
  import Bamboo.PostmarkHelper

  def some_email do
    email
    |> tag("some-tag")
  end
end

Sending extra parameters

You can send other extra parameters to Postmark with the put_param helper.

See Postmark's API for a complete list of parameters supported.

email
|> put_param("TrackLinks", "HtmlAndText")
|> put_param("TrackOpens", true)
|> put_param("Attachments", [
  %{
    Name: "file.txt",
    Content: "/some/file.txt" |> File.read!() |> Base.encode64(),
    ContentType: "txt"
  }
])

Changing the underlying request configuration

You can specify the options that are passed to the underlying HTTP client hackney by using the request_options key in the configuration.

Example

config :my_app, MyApp.Mailer,
      adapter: Bamboo.PostmarkAdapter,
      api_key: "my_api_key",
      request_options: [recv_timeout: 10_000]
