SendGrid support is here to provide exceptional service and answering deliverability questions is part of that service. We can answer general delivery practices and look at your recent sending to help you see what recipient servers are doing with the emails you send. We can assist with anything related to the SendGrid account, but we in the support team do not have any direct contacts we can share or contact.
Our expert services team however does have delivery consultants who are able to leverage industry connections, and they can assist with getting more details directly from the recipient service providers. There is an additional cost associated with engaging expert services. More details can be found here:
