Got my email code for PS5 but have a question.

I have two ea accounts, both have been signed up for the skate play test. The account that got approved for the playtest is not linked to my main PSN. I can't change the linked psn since it has my Apex info tied to it. I linked another psn to the account that got accepted. 

Today I get the email code but it got sent to the other EA account email. Not the email that I got accepted last week.  Now I'm not sure which psn to use?  Does anyone have any idea? Or does it matter. They say in the email with the code to use the account that got the email. I'm super confused why I got the email for a different account.
