Developing Email Contacts Through Wedding Lists

If you're stuck for ways of developing your email maketing list, you may want to consider a technique that a leading UK department store uses. The other day I went on the John Lewis (UK department store) to purchase some wedding gifts for a friend's wedding. On 'checking out'  I was presented with the following invitation:

It is quite a simple technique to use, though I would suggest that John Lewis invite people to sign up for a newsletter instead of asking them to 'opt-out' if they don't want to receive any email correspondence. This is a wonderfully cheap way of acquiring new customers: let people put their wedding lists online, invite their guests to order online and then try and convert the wedding guests to customers!
