I would continue to send e-mails, but perhaps not as frequently. If your child gets grades quarterly, send them an update quarterly, and include the other info you would have provided on a more regular basis. While the NCP is not responding, you need to continue to show you're propensity to actively support the child- NCP's relationship under the Code of Virginia § 20-124.3. Best interests of the child; visitation, Part 6:
"6. The propensity of each parent to actively support the child's contact and relationship with the other parent, including whether a parent has unreasonably denied the other parent access to or visitation with the child"
