HI Welcome to JustAnswer
Please try to open your email id and check if you still have access to it. Also remember , Do not click on any links given in that email to login to your account as it seems some is trying to hack your account by sending such emails to you.
Directly go to that email service providers website and try to open your email.
Let me know if you are unable to login to your account.
If you are able to login, I would suggest you to change your password.Add phone number and alternate email id to it so that other's can not hack it and you can recover your account any time you want.
If required, I can remotely connect to your machine and fix all the security loop holes in your account and make it hack prof.
