We call this "throttling". For a detailed description of this practice, please see Throttling deliveries of email when the ISP is rejecting emails

My subscriber's ISP fixed the problem. How can we start delivering email to them again?

If the ISP has resolved the issues, you can have our system stop "throttling" that subscriber's delivery. You can make this change manually as opposed to allowing our system to automatically decide when to try the next delivery.
