Sinatra

This guide shows you how to integrate Mailtrap with Sinatra and send emails using the Email API.

Before we start, you'll need to:

• Verify your sending domain

• Create and save an API key

Send emails using Sinatra and Mailtrap

To integrate Mailtrap and send emails via Sinatra, copy the following script into your configuration:

app.rb

require "sinatra"
require "mailtrap"

set :port, 5000
set :bind, "0.0.0.0"

get "/" do
  content_type :json

  mail = Mailtrap::Mail.from_content(
    from: { name: 'Mailtrap Test', email: 'YOUR-EMAIL-HERE' },
    to: [{ email: 'RECIPIENT-EMAIL-HERE' }],
    subject: 'Hello World',
    html: '<strong>it works!</strong>',
  )

  client = Mailtrap::Client.new(api_key: 'YOUR-MAILTRAP-API-KEY-HERE')
  response = client.send(mail)

  response.to_hash.to_json
end

Once you copy the script, make sure to:

• Insert your Mailtrap API token in the api_key: field

• Enter your email address in the from: field

• Enter your recipient's email address in the to: field
