class Aws::Rails::Sesv2Mailer

client instance.
Uses the AWS SDK for Ruby’s credential provider chain when creating an SESV2
config.action_mailer.delivery_method = :sesv2
(e.g. RAILS_ROOT/config/environments/production.rb)
use this for ActionMailer in your environment configuration
Once you have an SESv2 delivery method you can configure Rails to
Service V2.
Provides a delivery method for ActionMailer that uses Amazon Simple Email

def deliver!(message)

correctly. Called during mail delivery.
Rails expects this method to exist, and to handle a Mail::Message object 
def deliver!(message)
  params = { content: { raw: { data: message.to_s } } }
  # smtp_envelope_from will default to the From address *without* sender names.
  # By omitting this param, SESv2 will correctly use sender names from the mail headers.
  # We should only use smtp_envelope_from when it was explicitly set (instance variable set)
  params[:from_email_address] = message.smtp_envelope_from if message.instance_variable_get(:@smtp_envelope_from)
  params[:destination] = {
    to_addresses: to_addresses(message),
    cc_addresses: message.cc,
    bcc_addresses: message.bcc
  }
  @client.send_email(params).tap do |response|
    message.header[:ses_message_id] = response.message_id
  end
end

def initialize(options = {})

Parameters:
  • options (Hash) -- Passes along initialization options to 
def initialize(options = {})
  @client = SESV2::Client.new(options)
  @client.config.user_agent_frameworks << 'aws-sdk-rails'
end

def settings

ActionMailer expects this method to be present and to return a hash. 
def settings
  {}
end

def to_addresses(message)

When smtp_envelope_to was set, use it explicitly for to_address only.
SES v2 API prefers each component split out into a destination hash.
smtp_envelope_to will default to the full destinations (To, Cc, Bcc) 
def to_addresses(message)
  message.instance_variable_get(:@smtp_envelope_to) ? message.smtp_envelope_to : message.to
end
