def list_unsubscribe(*variables)
  set_single('h:List-Unsubscribe', variables.map { |var| "<#{var}>" }.join(','))
end

#message_id(data = nil) ⇒ void

This method returns an undefined value.

Set the Message-Id header to a custom value. Don’t forget to enclose the Message-Id in angle brackets, and ensure the @domain is present. Doesn’t use simple or complex setters because it should not set value in an array.

Parameters:

  • data (string) (defaults to: nil) —

    A string of data for the parameter. Passing nil or empty string will delete h:Message-Id key and value from @message hash.

  set_single(key, data)
end

#reply_to(address, variables = nil) ⇒ void

This method returns an undefined value.

Set the message’s Reply-To address.

Rationale: According to RFC, only one Reply-To address is allowed, so it is okay to bypass the set_multi_simple and set reply-to directly.

Parameters:

  • address (String) —

    The email address to provide as Reply-To.

  • variables (Hash) (defaults to: nil) —

    A hash of variables associated with the recipient.
