We've been using ClickDimensions fairly heavily over these last two years, and as a result the data it captures is starting to take up a large amount of space in our system.
One item we are considering is removing old "Sent Email" records from the system (as this is the largest chunk of data).
If we purge the individual Sent Email records, will this have any impact on the global per Email Send records count totals. (i.e. would it mess up the "Deliveries" count), or cause any other issues (like resending of the messages since there wasn't a log record for it)?
