Dear [insert IT contact name here]
We’ve started using a new service called LeadPro that will be sending us leads by email. We’ve noticed that we are not receiving their emails, but they can confirm that they are being correctly delivered to us.
I believe that the email are going into quarantine. They have provided me with a link to a Microsoft guide that walks through the steps to release emails from quarantine – https://docs.microsoft.com/en-gb/microsoft-365/security/office-365-security/find-and-release-quarantined-messages-as-a-user
The emails will be from a sender called LeadPro and they will be sent from this domain: @notify.propertytechnology.co.uk
