How can I unblock my account as an end user? 

Here are some steps you can take to clean up the email coming from your account:

1. Secure your account against compromise by spammers:
   • Change your password. Ensure your new password has a minimum length of eight characters and uses a mixture of upper and lower case letters, numbers, and special characters.
     
   • Verify that your operating system is running with the latest security updates.
   • Update your anti-virus software and conduct a full scan of your system to ensure that a spammer has not installed spam-sending malware on your computer.
2. If you have recently sent a newsletter or other type of mass mailing from your account, verify that none of the URLs within your messages have been flagged by anti-spam systems. Use the Trusted Source URL check to check a URL or domain's reputation. Generally speaking, make sure you are following best practices when sending a bulk campaign, such as using an opt-in only mailing list.
3. Sanitize your mailing list and ensure you are sending mails to only receivers who have opted in to receive your mail.

If these steps do not resolve the problem, please file a support request with your web hosting provider.
