Hi Cadman,

Do you mean a blackbook service? If so you could try http://racingandsports.com.au they email you usually two days before your horse is about to run. 90% reliable 10% unreliable - missed a couple of runners the last month or so.

If you mean auto alert to tab fluctuations as per your previous post, you would need to monitor TAB fluctuations in "real-time", no email service would be able to email you in time as the bulk of money goes on in the last two minutes before the jump.

My experience of tote plunges are not that the horses have any greater chance of winning, it's merely a correction inline with approximate on-course odds available.
