Unable to provide Conformation email for Spore

I orignally bought spore on Steam back in 2020. But since I have deleted the email. I now want the online access stuff. I have my EA and  steam account linked. I have the proof of purchase on steam but no longer have the email. I have 0 way of getting the email back. I dont want to spend another $20 on a game from 2008. I am just unsure of what I can do to get an online account. I simply just want to see my achievements but I need an online account to do so. I have tried the other ways to try and get the CD code but those ways seem to no longer work. I have sat for 2 hours talking with a agnet just for no answers on what I could do.
