[2023] Jagex account

I recently created a jagex account and added my RuneScape account to it. But when I try to sign in using the normal method I am used to (email address which isn't the same as jagex account email address) it does not work.

That's intentional, you no longer use those login details to play, instead using the newly created Jagex Account to do so.
