Converting External CSS to Inline CSS for Mail in Rails

Question

I am trying to create an application that will send out style-heavy emails and have required clients working except Google\'s Gmail. I researched the issue and it looks like Gma

Answer 1

Added premailer:

def premailer(message)
  message.text_part.body = Premailer.new(message.text_part.body.to_s, with_html_string: true).to_plain_text
  message.html_part.body = Premailer.new(message.html_part.body.to_s, with_html_string: true).to_inline_css

  return message
end

def welcome(user)
  @user = user

  message = mail ...
end
