Email Issues

It looks as though we  have gotten our email issues under control, but please still keep the below in mind, just incase we happen to get hacked again (since it does happen frequently to everybody)

Some of you have been having issues recieving our emails, and we cannot figure out why, so I contacted Outlook Support to see if they could figure out the issue, and below is the response that I recieved.  So would everyone please contact your support if you are not recieving our emails or are having issues with our emails.


Good day! thank you for getting back to us. Upon looking at the data that you sent to me I see that the affected email address are third party domain. I would like to suggest to contact the provider or the user that they need to contact their support since they are unable to receive a specific email. With our further investigation since there is a specific user is affected, there is a possibility that these users are blocking your email or land in junk, another possibility that their provider is blocking your email.
