The satellite broadcaster includes a letter in its monthly Sky Magazine aimed at promoting the benefits of its plans to use customer information to provide "personalised services, such as providing you with viewing recommendations and tailored advertising".
The letters will go out to customers in phases. Up to one million of Sky's 10 million registered homes will receive the letter in the first phase, which will be accompanied by editorial in the magazine.
Explaining the benefits of AdSmart, the letter highlights how programmes similar to the ones you've watched before can be recommended. It said: "We'll also be able to make some of the advertising you see more relevant to you.
"We'll take some of the information you've provided to us – such as your post code or TV package – to build up a picture of what types of products and services might be of interest to you."
Earlier this month at the ISBA conference, : "AdSmart will make targeted advertising work harder and smarter. The prize is considerable, so we are taking the time to make sure we do get it right."
A Sky Spokesperson said: "We think our customers will respond positively to upcoming innovations such as content recommendations and tailored advertising. But, we recognise that our customers have a choice, and we want to give them all the information they need in order to an informed decision.
"We are excited by the opportunities presented by the Sky+HD box and will continue to keep customers updated on what we're working on."
Sky's AdSmart has served targeted ads to customers online through the Sky Player since 2010 but does not plan on launching the service fully across TV sets until 2013.
