IanLindgren Can you give us some details about your setup - I'm confused regarding your comments saying your website was marked as suspicious but it's your email being blocked?   

 

Do you mean your IP address was blacklisted or the domain name for emails?  

 

Do you have an on-premise mail server or Exchange Online?   

 

If you use MXToolbox to check for blacklisting your domain/IP, does it show anything?

    PaulaSillars Thank you for helping.  It is the website IP and the domain that was then blacklisted and despite it being removed more than 50% of our emails are not received.  So the short term fix has been to purchase a similar domain and send using that domain name to guarantee delivery and a reply goes back to us through an alias (I believe it’s called).  MXTools could find no issues, but thank you for your help.
