How do I register my domain so Hotmail will stop blocking my customer emails?

My online store has been active for 6 years but lately it seems all of my customers who use Hotmail are not getting my emails. The emails don't go into SPAM, they just disappear. This is quite frustrating for both my staff and my customers. What do i need to do to show Hotmail I am not a spammer?
