Recently I got Atlas card and initially I did not receive the 25% bonus points email but I received it yesterday just when I linked my Accor id to Axis travel edge.
Not sure but maybe that could have triggered the mail.
I transferred Edge miles to Accor after receiving the mail, transfer is still in process. But not sure if I will receive 25% extra points due to following condition:
"All Cardholders must be previously registered as a program member of the ALL – Accor Live
Limitless, Accor’s loyalty program in order to participate in this promotion."
