Quoter: Email deliverability to Microsoft-based emails is failing. SendGrid, our third party email delivery partner, has confirmed that Microsoft has erroneously blocked a massive number of IPs. We are working to resolve this with Microsoft as quickly as possible, as our sending reputation is extremely high and there is no reason for us to be added to their block list.
