Received this email from NatGeo Kids magazine today. I can see 6 issues currently available (November 2019 to April 2020)
The email appears to be targeted to current subscribers (I can't see any mention of it in the website), but the link is public.
This is a challenging time for parents, and we want to help as best we can to engage, entertain and inspire children to care about our planet – even if they currently can’t go out and enjoy the natural world.
Our website is full of fun and engaging content that can help keep children learning whilst they are at home, and we have also now made our entire back catalogue of magazines free to access via our digital portal. We hope that this gives kids all over the country a way to learn about our world and all the amazing people and animals in it.
