New card? They usually have random things like this when you first get your card.
they normally give this type of offer to new card, previously it's something like spend $20 and get $10 back
Good deal if you're one of the lucky chosen few.
I spend enough already they didn't need to encourage me
Got the email but no offers.

I got the offer! Card holder since 2012.
According to my email, this is only visible inside the official AmEx app. It worked on all 3 primary card holders (Qantas Discovery) in my family but not supplementary cards. All I did was log in to each account via the official American Express app, and it's ready to activate. I've been a member since 2017, family member maybe 2015.
