Okay, but how many print projects per week do you have? Let's say 5. How many proofs do you work through on an average project? Let's say 4, three that get corrected and a final verison. If you have the typical customer-project manager-graphic artist project sequence, that implies a minimum of 5 x (2+4x8) = 170 e-mails/week will be sent between these 3 persons.

And what about billing? Do you have record of all clients' requests mentioned in their e-mails?

With WebProof, billing almost becomes fun - you just print out the log and attach to your invoice!
