If you're still working on this, the way to handle this would be through a Publication. However, I'm not sure whether Publications are available in BusinessObjects XI, which is what I assume you're using based on the version of Crystal. Unless "11" is from "2011", in which case this will work.

You would create a report off of the customer data table that includes the name, email address, and relevant fields for filtering the original report for each customer. The original report becomes the "Source Document" and the customer report becomes the "Dynamic Recipients" document. Under "Personalization" you'll match the fields from the customer report to the matching fields in the source report. Set up format and destination, then schedule the publication. It will automatically burst the source report and send it to the customers.
