Another possible consideration in comparing the telegraph to email is that the telegraph, even in automated form, usually involved human intervention and/or transcription of some kind.  Until teleprinters came along, (relatively late in the telgraphy game) not many people received messages directly (with the exception of stock tickers, the antecedent of the teleprinter).
