I'm new here so a big HELLO!

I was needing help so stumbled across this website.

I'm looking to create a website which would send out a email automatically to Person A (example) when i receive an update from another website.

Basically its this -

Receive a RNS from here(http://www.londonstockexchange.com/e...news-home.html) -> Send Email instantly to Person A when there interested company releases an update.

Not sure what i would be looking at for creating this this kind of service?
Never done this type of thing before!

Here is another website does the same http://www.rnsalert.com/

Issue with them is that some of the updates are a bit delayed!
