Sorry dsc, I was just being thorough with the process as I understand it.
It should be a straightforward case of receiving it on the day of release or shortly after dispatch by the company rather than the confirmed delivery as after all you have pre-ordered and successfully purchased the game, but often they’ve been linked like that.
I remember with Hitman 1 / Hitman 2016 there were codes in the game box - with Hitman 3 it looks as if it’s a standard game box (standard or deluxe), with the deluxe having inside it the deluxe redeem code and if you ordered it from a distributor that also has the passport, it’s included in the shipped package.
It might be that they’re busy with orders and their system is overwhelmed and the email with the code will come soon.
I do have a theory if you’ll permit me, it might confuse things further or might clarify things. I was looking at ShopToNet as I wasn’t aware of this store until you brought it up.

On their website, Hitman Deluxe title and description, etc does not mention Trinity Pack other than a small image from IOI’s marketing: https://www.shopto.net/userdata/dcshop/campaign_images/248_hitman_3_deluxe_edition_beauty_shot.jpg
The standard editions however all say Hitman 3 + Trinity Pack. I wonder if when they set it up on their system, they accidentally didn’t set the Deluxe Edition purchases for the trinity pack codes. In which case now that you’ve contacted them they should be able to get you the code manually.
It looks like their support options are a telephone or a support ticket system - their phones are open 9am-6pm so you could try calling them if you don’t want to wait.
I remember when Hitman 2 came out and I had the pre-order + sniper assassin access, I had to chase the game distributor / seller as well to get the code as they hadn’t included it in the game / package or provided it via email, etc. Eventually they gave me the stuff I’d paid for 
Rafael they must have pre-order codes if they’re selling you the pre-order game - IOI would have issued them stock they purchased with a set of codes.
