Setting Custom Headers When Sending A Message

[Chris Rothstein]

I am using the mail gem and I was curious if anyone knows how to setup custom headers.  I am using Mailgun for sending email and I am trying to pass a custom variable to them via a header.  I need to send over a header with the name "X-Mailgun-Variables" and a value that is a string. I can't seem to find any documentation on how to do this. My code is below:

mail = Mail.deliver do

      to to

      from "#{name} <#{from}>"

      subject subject

      bcc bcc_to

      

      text_part do

        body text

      end 

      if user_has_signature

        html_part do

          content_type 'text/html; charset=UTF-8'

          body html_text

        end

      end

Try this:

mail = Mail.new do

  to to

  from "#{name} <#{from}>"

  subject subject

  bcc bcc_to

      

  text_part do

    body text

  end 

  if user_has_signature

    html_part do

      content_type 'text/html; charset=UTF-8'

      body html_text

    end

  end

end

mail['X-Mailgun-Variables'] = "YOUR STRING"

mail.deliver!
