I don’t think there’s a way to recover it unless you change the email address associated with the account—if that’s even possible. Alternatively, you might be able to recover it through a phone number, if one is linked to the account. Otherwise, I don’t see a way to recover it. If possible, try reactivating the deleted email. Or, if you have an account linked to it (like PlayStation, Xbox, or Steam), you can use one of those. That’s actually how I sign into my EA account. If all fails Sims 3 is literally $19.99 on Steam I don't think it would hurt to spend $20
