This Gem allows you to quickly and easily send emails through SendGrid's Web API using native Ruby.
You can read our official documentation on the Web API's Mail feature here.
Add this line to your application's Gemfile:
gem 'sendgrid-ruby'
And then execute:
$ bundle
Or install it yourself using:
$ gem install sendgrid-ruby
Create a new client with your SendGrid API Key.
require 'sendgrid-ruby'
# As a hash
client = SendGrid::Client.new(api_key: 'YOUR_SENDGRID_APIKEY')
# Or as a block
client = SendGrid::Client.new do |c|
c.api_key = 'YOUR_SENDGRID_APIKEY'
endCreate a new Mail object and send:
mail = SendGrid::Mail.new do |m|
m.to = '[email protected]'
m.from = '[email protected]'
m.subject = 'Hello world!'
m.text = 'I heard you like pineapple.'
end
res = client.send(mail)
puts res.code
puts res.body
# 200
# {"message"=>"success"}You can also create a Mail object with a hash:
res = client.send(SendGrid::Mail.new(to: '[email protected]', from: '[email protected]', subject: 'Hello world!', text: 'Hi there!', html: '<b>Hi there!</b>'))
puts res.code
puts res.body
# 200
# {"message"=>"success"}Attachments can be added to a Mail object with the add_attachment method. The first parameter is the path to the file, the second (optional) parameter is the desired name of the file. If a file name is not provided, it will use the original filename.
mail.add_attachment('/tmp/report.pdf', 'july_report.pdf')Inline content can be added to a Mail object with the add_content method. The first parameter is the path to the file, the second parameter is the cid to be referenced in the html.
mail = SendGrid::Mail.new do |m|
m.to = '[email protected]'
m.from = '[email protected]'
m.subject = 'Hello world!'
m.text = 'I heard you like the beach.'
m.html = 'I heard you like the beach <div><img src="cid:beach"></div>'
end
mail.add_content('/tmp/beach.jpg', 'beach')
result = client.send(mail)params = {
:to,
:to_name,
:from,
:from_name,
:subject,
:text,
:html,
:cc,
:cc_name,
:bcc,
:bcc_name,
:reply_to,
:date,
:smtpapi,
:attachments,
:template
}Params can be set in the usual Ruby ways, including a block or a hash.
mail = SendGrid::Mail.new do |m|
m.to = '[email protected]'
m.from = '[email protected]'
end
client.send(SendGrid::Mail.new(to: '[email protected]', from: '[email protected]'))Using the :to param, we can pass a single email address as a string, or an array of email address strings.
mail = SendGrid::Mail.new
mail.to = '[email protected]'
# or
mail.to = ['Example Dude <[email protected]>', '[email protected]']
# or
mail.to = ['[email protected]', '[email protected]']mail = SendGrid::Mail.new
mail.from = '[email protected]'As with :to, :cc can take a single string or an array of strings.
mail = SendGrid::Mail.new
mail.cc = ['[email protected]', '[email protected]']As with :to and :cc, :bcc can take a single string or an array of strings.
mail = SendGrid::Mail.new
mail.bcc = ['[email protected]', '[email protected]']mail = SendGrid::Mail.new
mail.subject = 'This is a subject string'Using the :text param allows us to add plain text to our email body.
mail = SendGrid::Mail.new
mail.text = 'WHATTUP KITTY CAT!?'Using the :html param allows us to add html content to our email body.
mail = SendGrid::Mail.new
mail.html = '<html><body>Stuff in here, yo!</body></html>'The :template param allows us to specify a template object for this email to use. The initialized Template will automatically be included in the smtpapi header and passed to SendGrid.
template = SendGrid::Template.new('MY_TEMPLATE_ID')
mail.template = templateAnother easy way to use the SendGrid Templating system is with the Recipient, Mail, Template, and TemplateMailer objects.
Create some Recipients
users = User.where(email: ['[email protected]', '[email protected]'])
recipients = []
users.each do |user|
recipient = SendGrid::Recipient.new(user.email)
recipient.add_substitution('first_name', user.first_name)
recipient.add_substitution('city', user.city)
recipients << recipient
endCreate a Template
template = SendGrid::Template.new('MY_TEMPLATE_ID')Create a Client
client = SendGrid::Client.new(api_user: my_user, api_key: my_key)Initialize mail defaults and create the TemplateMailer
mail_defaults = {
from: '[email protected]',
html: '<h1>I like email</h1>',
text: 'I like email',
subject: 'Email is great',
}
mailer = SendGrid::TemplateMailer.new(client, template, recipients)Mail it!
mailer.mail(mail_defaults)To utilize the X-SMTPAPI header, we have directly integrated the SendGridJP/smtpapi-ruby gem. For more information, view our SMTPAPI docs page.
header = Smtpapi::Header.new
header.add_to(['[email protected]', '[email protected]'])
header.add_substitution('keep', ['secret']) # sub = {keep: ['secret']}
header.add_substitution('other', ['one', 'two']) # sub = {keep: ['secret'], other: ['one', 'two']}
header.add_unique_arg("unique_code", "8675309")
header.add_category("Newsletter")
header.add_filter('templates', 'enable', 1) # necessary for each time the template engine is used
header.add_filter('templates', 'template_id', '1234-5678-9100-abcd')
header.set_ip_pool("marketing_ip_pool")
