I should have added, if your email account was hacked, the hackers will have stolen your contacts list. This can not be un-stolen so you and your contacts may find that they will receive scam emails purporting to be from you for ever more.
You should make your contacts aware you were hacked and advise them to be very careful if they receive any emails from you that that ask for anything or ask them to click on a link within the email.
You should also have a read through this link and follow it and the sub links advice. I would also suggest that if you have not done it already you should contact your bank and any other place that you use the email address and advise them you were hacked.

As annoying as it may be you may find that ultimately the best thing to do is to stop using that email address and advise your contacts that should they receive any emails from it to treat it as spam and delete it immediately.
