The WordAds team has now launched paid advertising in email subscriptions. This is a new channel for WordAds sites to increase earnings. This feature requires nothing from WordAds sites on WordPress.com. Site owners who want to opt out can simply make a support request. We plan to roll out to Jetpack Ads users as well.

You can be assured that the email advertising program is in compliance with privacy norms and regulations.
