First, we recommend checking your SPAM box. Also, make sure you are not using a website-based email address (@YourBusinessURL). Email addresses connected to a business website have a high rate of failure when receiving email because of the web host settings. Use Gmail, Yahoo, Hotmail, or Outlook.com for best results.
If you have checked your SPAM and you are NOT using an email address associated with your business website, then it's possible that your subscription has ended and you didn't renew. You can signup for another year HERE
