opt in email late

so last week i got that promo email but i saw it like two days after it landed in my inbox. already missed the window for the free spins, kinda annoying since i actually play those games a lot. do you guys just check your promo tab every day or is there some better way to catch these? i feel like the promos are so random, sometimes i get them, sometimes not. i’m kinda blaming myself but also, they should give us more time. i dunno, your call.
