This library allows you to quickly and easily use the Twilio SendGrid Web API v3 via Ruby.

Version 3.X.X+ of this library provides full support for all Twilio SendGrid Web API v3 endpoints, including the new v3 /mail/send.

This library represents the beginning of a new path for Twilio SendGrid. We want this library to be community driven and Twilio SendGrid led. We need your help to realize this goal. To help make sure we are building the right things in the right order, we ask that you create issues and pull requests or simply upvote or comment on existing issues or pull requests.

If you need help using SendGrid, please check the Twilio SendGrid Support Help Center.

Update the development environment with your SENDGRID_API_KEY, for example:

echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env
echo "sendgrid.env" >> .gitignore
source ./sendgrid.env

Add this line to your application's Gemfile:

gem 'sendgrid-ruby'

And then execute:

bundle

Or install it yourself using:

gem install sendgrid-ruby

The following is the minimum needed code to send an email with the /mail/send Helper (here is a full example):

require 'sendgrid-ruby'
include SendGrid

from = SendGrid::Email.new(email: '[email protected]')
to = SendGrid::Email.new(email: '[email protected]')
subject = 'Sending with Twilio SendGrid is Fun'
content = SendGrid::Content.new(type: 'text/plain', value: 'and easy to do anywhere, even with Ruby')
mail = SendGrid::Mail.new(from, subject, to, content)

sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client.mail._('send').post(request_body: mail.to_json)
puts response.status_code
puts response.body
puts response.parsed_body
puts response.headers

For more complex scenarios, please do not use the above constructor and instead build your own personalization object as demonstrated here.

The following is the minimum needed code to send an email without the /mail/send Helper (here is a full example):

require 'sendgrid-ruby'
include SendGrid

data = JSON.parse('{
  "personalizations": [
    {
      "to": [
        {
          "email": "[email protected]"
        }
      ],
      "subject": "Sending with Twilio SendGrid is Fun"
    }
  ],
  "from": {
    "email": "[email protected]"
  },
  "content": [
    {
      "type": "text/plain",
      "value": "and easy to do anywhere, even with Ruby"
    }
  ]
}')
sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client.mail._("send").post(request_body: data)
puts response.status_code
puts response.body
puts response.parsed_body
puts response.headers

require 'sendgrid-ruby'
sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client.suppression.bounces.get()
puts response.status_code
puts response.body
puts response.parsed_body
puts response.headers

require 'sendgrid-ruby'
sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client._("suppression/bounces").get()
puts response.status_code
puts response.body
puts response.parsed_body
puts response.headers
