📭 Unsubscribe

Automatically unsubscribe from emails in Rails.

Demo

🚀 Installation

And then execute:

$ bundle

Or install it yourself as:

Then run the installation commands:

📚 Usage

Unsubscribe::Owner

  • Add include Unsubscribe::Owner to a Model. The Model must have an email column.
class User < ApplicationRecord
  include Unsubscribe::Owner
end

# => #<ActiveRecord::Associations::CollectionProxy [#<Unsubscribe::MailerSubscription>, #<Unsubscribe::MailerSubscription>] >

User.first.subscribed_to_mailer? "MarketingMailer"
# => true/false

User.first.to_sgid_for_mailer_subscription
# => #<SignedGlobalID:123 ...>

Unsubscribe::Mailer

  • Add include Unsubscribe::Mailer to a Mailer.
  • Optionally call unsubscribe_settings to set a name and description. This will be used in the unsubscribe page.
  • Set mail to: to @recipient.email. The @recipient is an instance of whatever Class include Unsubscribe::Owner was added to.
class MarketingMailer < ApplicationMailer  
  include Unsubscribe::Mailer

  unsubscribe_settings name: "Marketing Emails", description: "Updates on promotions and sales."

  def promotion
    mail to: @recipient.email
  end  
end
  • Call the Mailer with a recipient parameter.
  MarketingMailer.with(
    recipient: User.first
  ).promotion.deliver_now
