I've heard this so many times but I'm not sure it is true.
I helped with processing the results of a large government RFC for a large government aid bill (Farm Bill 201?) and the exact opposite was true. There were too many responses to individually read each one so the responses just got bucketed and counted. You could be fine with a one off response but it would be less likely to be bucketed correctly and would still only be counted once per bucket at most.
To cover your bases I would always do the easy one click option and then write the handwritten letter as well.
