chloeslloyd,
I have moved your post because the thread you posted on was over 3 years old with the last post over a year ago.
Why do you think your email account has been hacked?
If your account was hacked, your contacts details would have been harvested by the hacker. If that is the case, having your email account deleted will not stop emails being sent to your contacts. The hacker will be using a spoof of your email address to send the emails. They are not coming from your account.
If you do have your account deleted you would need to inform all of your contacts to stop opening any emails from that account and mark them as spam.
