SendgridToolkit

Build Status

SendgridToolkit is a Ruby wrapper for the Sendgrid Web API

Supported Modules

SendgridToolkit provides a class for interacting with each of the following Sendgrid API modules:

  • Bounces
  • InvalidEmails
  • Mail
  • SpamReports
  • Statistics
  • Unsubscribes

Consuming the Sendgrid API is as simple as instantiating a class and making the call:

unsubscribes = SendgridToolkit::Unsubscribes.new("username", "api_key")
unsubscribes.add :email => "[email protected]"

Two lines, and voila!

Common actions are documented below under each module. For more details, visit the Sendgrid Web API Documentation

Contributing

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
  • Fork the project
  • Start a feature/bugfix branch
  • Commit and push until you are happy with your contribution
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.

Big thanks to James Brennan for refactoring old code and writing the Bounces, InvalidEmails and SpamReports modules.

Install

Via rubygems.org:

$ gem install sendgrid_toolkit

Or add it to your Gemfile

gem 'sendgrid_toolkit', '>= 1.1.1'

Setting your API credentials globally

Setting your API user and key once globally for all API access:

SendgridToolkit.api_user = "bob"
SendgridToolkit.api_key = "x123y"

If you do this when you create individual API objects you will not need to pass the api_user or api_key

bounces = SendgridToolkit::Bounces.new

Bounces Module

The bounces module provides access to all of your bounces.

Instantiate the Bounces object:

bounces = SendgridToolkit::Bounces.new(api_user, api_key)

Retrieve bounces:

all_bounces = bounces.retrieve

all_bounces will be an array of hashes, each of which contains the following keys:

  • email: the recipient's email address
  • status: the status of email
  • reason: the reason for the bounce, as specified by the recipient's email server

Get the timestamp of each bounce:

all_bounces = bounces.retrieve_with_timestamps

Each hash in all_bounces will now contain a created key, which holds a Ruby Time object.

If you believe an email address will no longer bounce and would like Sendgrid to deliver future emails to that address, you may delete the Bounce entry:

bounces.delete :email => "[email protected]"

InvalidEmails Module

The InvalidEmails module provides access to all of your email addresses.

Instantiate the InvalidEmails object:

invalid_emails_obj = SendgridToolkit::InvalidEmails.new(api_user, api_key)

Retrieve invalid emails:

invalid_emails = invalid_emails_obj.retrieve

invalid_emails will be an array of hashes, each of which contains the following keys:

  • email: the recipient's email address
  • reason: the reason the email address is believed to be invalid

Get the timestamp that each email was determined to be invalid:

invalid_emails = invalid_emails_obj.retrieve_with_timestamps

Each hash in invalid_emails will now contain a created key, which holds a Ruby Time object.

If you believe a once-invalid email address is now valid and would like Sendgrid to deliver future emails to that address, you may delete the InvalidEmail entry:

invalid_emails.delete :email => "[email protected]"

Mail Module

The Mail module lets you send email via the web API.

Call :send_mail (chosen to avoid conflicts with Object:send) with the standard parameters:

SendgridToolkit::Mail.new(api_user, api_key).send_mail :to => "[email protected]", :from => "[email protected]", :subject => "Some Subject", :text => "Some text"

The complete set of "x-smtpapi" options are also supported. You can use them like:

SendgridToolkit::Mail.new(api_user, api_key).send_mail :to => "[email protected]", :from => "[email protected]", :subject => "Some Subject", :text => "Some text", "x-smtpapi" => {:category => "Retention"}

SpamReports Module

The SpamReports module provides access to all email addresses that have reported you for spam.

Instantiate the SpamReports object:

spam_reports_obj = SendgridToolkit::SpamReports.new(api_user, api_key)

Retrieve spam reports:

spam_reports = spam_reports_obj.retrieve

spam_reports will be an array of hashes, each of which contains an email key, indicating the email address that reported you for spam.

Get the timestamp of each spam report:

spam_reports = spam_reports_obj.retrieve_with_timestamps

Each hash in spam_reports will now contain a created key, which holds a Ruby Time object.

If you believe a user will no longer consider your content to be spam, you may delete the SpamReport entry:

spam_reports.delete :email => "[email protected]"

Statistics Module

The statistics module provides access to all of your email statistics.

Instantiate the Statistics object:

statistics = SendgridToolkit::Statistics.new(api_user, api_key)

Retrieve statistics:

stats = statistics.retrieve

stats will be an array of hashes, each of which contains the following keys:

  • date: The date to which the statistics in this hash refer to
  • requests: The number of emails you sent
  • bounces: The number of users who opened your email but did not click on your links
  • clicks: The number of users who clicked on a link in your email
  • opens: The number of users who opened your email
  • spamreports: The number of users who have reported your emails as spam

stats may also contain some keys that Sendgrid does not officially document, such as: delivered, invalid_email, repeat_bounces,+repeat_spamreports, repeat_unsubscribes and unsubscribes

To narrow your retrieval to the past 5 days:

stats = statistics.retrieve :days => 5

To narrow your retrieval to emails within the last month but before one week ago:

stats = statistics.retrieve :start_date => 1.month.ago, :end_date => 1.week.ago

To narrow your search to a particular category (applicable only if you use this Sendgrid feature):

stats = statistics.retrieve :category => "NameOfYourCategory"

Note: You may combine a category query with other options, i.e.:

stats = statistics.retrieve :category => "NameOfYourCategory", :days => 5

Receive your all-time statistics:

stats = statistics.retrieve_aggregate

stats will be a single hash containing all of the aforementioned keys except date.

If you use Sendgrid's category feature, you can list your categories:

cats = statistics.list_categories

cats is an array of hashes, each of which has a category key that holds the name of a category.

Unsubscribes Module

The unsubscribes module manages your list of unsubscribed email addresses.

Instantiate the Unsubscribes object:

unsubscribes = SendgridToolkit::Unsubscribes.new(api_user, api_key)

List everybody who has unsubscribed from your emails with:

listing = unsubscribes.retrieve

listing will be an array of hashes, each of which has an email key.

Get the timestamp when each user unsubscribed:

listing = unsubscribes.retrieve_with_timestamps

Each hash in listing will now contain a created key, which holds a Ruby Time object.

Unsubscribe a user from your sendgrid email:

unsubscribes.add :email => "[email protected]"

SendgridToolkit will throw UnsubscribeEmailAlreadyExists if the email you specified is already on the list

Remove a user from your unsubscribe list:

unsubscribes.delete :email => "email@that_is.unsubscribed"

SendgridToolkit will throw UnsubscribeEmailDoesNotExist if the email you specified is not on the list

A note about authentication

Each class is initialized with api_user and api_key parameters. api_user is your sendgrid account email address, and api_key is your sendgrid password.

If you don't supply api_user or api_key, SendgridToolkit will look for the SMTP_USERNAME or SMTP_PASSWORD environment variables. If they are not found, SendgridToolkit will throw NoAPIKeySpecified or NoAPIUserSpecified, depending on what you omitted.

If authentication fails during an API request, SendgridToolkit throws AuthenticationFailed.

In Case You're Curious...

API requests are made and responses are received in JSON. All requests are made as POSTs unless noted otherwise (Sendgrid's examples are via GET, but they support POST)

Each class takes a final options parameter in the form of a hash. You may use this parameter to pass additional options to the Sendgrid API. For example, let's say you are using the unsubscribes function:

unsubscribes = SendgridToolkit::Unsubscribes.new(api_user, api_key)
listing = unsubscribes.retrieve

If Sendgrid were to add a only_verified option to this API call, you could call:

listing = unsubscribes.retrieve :only_verified => true

to make use of it.

Testing

In addition to unit tests, SendgridToolkit comes with a limited suite of "webconnect" tests that will actually hit Sendgrid's servers and perform various actions for purposes of real-world testing. In order to use these tests, you must:

  1. Create a test account with sendgrid and store the credentials in TEST_SMTP_USERNAME and TEST_SMTP_PASSWORD environment variables. This is so that actions are performed on a test account and not your real Sendgrid account. If you forget, don't worry -- the tests will fail but they will not fall back on the account that uses SMTP_USERNAME and SMTP_PASSWORD.
  2. Change "xit" it "it" on the tests you wish to run.

Running "spec spec" out of the box will run the standard suite of tests (all network access is stubbed out).
