Answer 1

It appears that Magento 2 Email's TransportBuilder class doesn't support email attachments yet.

Since the default Message class inherits from Zend_Mail class, one workaround is to extend the TransportBuilder class and call $message's createAttachment method to send file attachment in email.

You can use following class in place of TransportBuilder class to build Transport object and include attachment.

use Magento\Framework\Mail\MessageInterface;
use Magento\Framework\Mail\TransportInterfaceFactory;
use Magento\Framework\ObjectManagerInterface;
use Magento\Framework\Mail\Template\FactoryInterface;
use Magento\Framework\Mail\Template\SenderResolverInterface;
use Magento\Framework\Mail\Template\TransportBuilder;
class UploadTransportBuilder extends TransportBuilder {
 public function __construct(FactoryInterface $templateFactory,
 MessageInterface $message,
 SenderResolverInterface $senderResolver,
 ObjectManagerInterface $objectManager,
 TransportInterfaceFactory $mailTransportFactory) {
 parent::__construct($templateFactory,
 $message,
 $senderResolver,
 $objectManager,
 $mailTransportFactory);
 }
 public function attachFile($file, $name) {
 if (!empty($file) && file_exists($file)) {
 $this->message
 ->createAttachment(
 file_get_contents($file),
 \Zend_Mime::TYPE_OCTETSTREAM,
 \Zend_Mime::DISPOSITION_ATTACHMENT,
 \Zend_Mime::ENCODING_BASE64,
 basename($name)
 );
 }
 return $this;
 }
}

Add return $this;:

public function attachFile($file, $name) {
 if (!empty($file) && file_exists($file)) {
 $this->message
 ->createAttachment(
 file_get_contents($file),
 \Zend_Mime::TYPE_OCTETSTREAM,
 \Zend_Mime::DISPOSITION_ATTACHMENT,
 \Zend_Mime::ENCODING_BASE64,
 basename($name)
 );
 }
 return $this;
 }
