Forgive me if I'm being more stupid than usual today and have misunderstood.
Do you want your script to E-mail you?
If so, (watch the purists flame me ;-) I often just use the Unix mail or mailx command within backticks - quick and dirty but does the job. Though using Mail::Sendmail is a nice Perl only solution.
However, if you want the cron line to mail you then I think it's possible but messy but IMHO there is no need for this. Don't worry about cron you can trust it. BTW if you are using a commercial ?nix then it is supported by the OS vendor.
I've used it for ten years on most ?nix flavours and the only problems were of my own devising
