Add the following to your user model:

  effective_postmark_user
end

And add two database fields to your user model:

class AddEffectivePostmarkFieldsToUsers < ActiveRecord::Migration[7.0]
  def change
    add_column :users, :email_delivery_error, :string
    add_column :users, :email_delivery_error_at, :datetime
  end
end

Then migrate the database:

rake db:migrate

Admin View

= effective_postmark_admin_alert(current_user, from: 'My Site')

Dashboard View

= effective_postmark_alert(current_user, from: 'My Site')

Devise Password Reset

If you want to include the inactive alert on the devise reset password page:

class Users::PasswordsController < Devise::PasswordsController
  after_action(only: :create) do
    if resource.email_delivery_error.present?
      flash.delete(:notice)
      flash[:danger] = view_context.effective_postmark_alert(resource, from: 'My Site', html_class: '')
    end
  end
end

Inactive Recipients Report

Add a link to the admin report:

= nav_link_to 'Email Delivery Errors', effective_postmark.email_delivery_errors_admin_postmark_reports_path

can :admin, :effective_postmark
can(:postmark_reactivate, User) { |user| user.email_delivery_error.present? }
