Quick setup examples

Ruby on Rails

Send your first email from a Rails controller by calling the MailBlastr API with Net::HTTP.

Ruby has an official gem — gem install mailblastr — and it works from any Rails controller or job. The example below shows the dependency-free alternative instead: POST JSON to https://www.mailblastr.com/api/emails with the standard-library net/http, so there is nothing to install. See SDKs for the gem.

Prerequisites

A MailBlastr API key.
A verified domain to send from.

1. Add your API key

Store your key in the environment (or Rails credentials). The example reads MAILBLASTR_API_KEY from ENV.

.env

MAILBLASTR_API_KEY=mb_xxxxxxxxx

2. Send email from a controller

POST the email body to the MailBlastr API from a controller action with net/http. The easiest way to send is with the html field.

app/controllers/send_controller.rb

require "net/http"
require "json"
require "uri"

class SendController < ApplicationController
  def create
    uri = URI("https://www.mailblastr.com/api/emails")

    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true

    request = Net::HTTP::Post.new(uri)
    request["Authorization"] = "Bearer #{ENV.fetch('MAILBLASTR_API_KEY')}"
    request["Content-Type"] = "application/json"
    request.body = {
      from: "Acme <onboarding@yourdomain.com>",
      to: ["delivered@mailblastr.dev"],
      subject: "hello world",
      html: "<strong>it works!</strong>",
    }.to_json

    response = http.request(request)
    render json: JSON.parse(response.body), status: response.code.to_i
  end
end

A successful call returns the created email's id. See every supported field in the Send an email reference.
