This emblem was available for a limited time around Taken King when you had to have your email linked to Bungie.net in order for them to send a confirmation email to everyone that could pick up their emblem in the emblem kiosk. It's most likely unavailable now.

That's not how you get it.

Exactly how to receive this emblem is unknown. I can give you a link to where Bungie replied to this topic https://www.bungie.net/en/Forum/Post/196673031/0/0/1 [quote]Occasionally, Bungie will disperse in-game items, such as Emblems, through emails to select groups of players who meet specific qualifications. These qualifications change from offer to offer. However, the initial qualification to receive these emails is that players need to have their Bungie.net profile settings configured to allow us to send announcements and notifications to their verified email address. If you are unsure if your settings are configured correctly, please see our help article: https://www.bungie.net/en/Help/Troubleshoot?oid=13784[/quote] Also, please note that it may take some time for you to receive one of these emails after getting your account set up to receive these sorts of emails from Bungie.

There is no exact way to receive this emblem. However the first step to possibly receiving it is linking your email with your bungie account. https://www.bungie.net/en/Forum/Post/196673031/0/0/1 Above is a link to bungie's comment on the issue:)
