If they are 'dedicated', doesn't matter if they are coming from
SendGrid, the PTR should reflect your clients domain.
host 149.72.234.90
90.234.72.149.in-addr.arpa domain name pointer
wrqvzxrx.outbound-mail.sendgrid.net.
And given the amount of abuse of SendGrid servers, anything you can do
to differentiate from their generic naming conventions will help you.
