DKIM and DMARC
Budget: $30 – $250 USD
Our domain is proservicesinc.com, there is a very similar domain proserviceinc.com which makes Gmail to think that the prior is spoofing the later. To prevent this, we need to enable DKIM and DMARC for the domain proservicesinc.com. I have guides on how to do this from Microsoft Office customer service, but I would rather have someone IT savvy take care of this.
