auto responder

Hi, I have question, when I received order with multiple items from different supplier when I change the status to order shipped, will my customer get email notification with all the tracking number? or I need to send them email manually? Thank you

Hello All, I am wondering what plug-in or email marketing service do you use for auto responder emails and transactional emails. I am looking for one that works and easy to set up. Can you please advise on why you have decided to go with that service? Thank you all for the awesome support...
