Not knowing your relationship, I personally feel 100 pages of email proof is too much unless you have remarkable red flags. Rather than having a lot in one kind of proof, you want to include fewer but more variety of proof from different events. Pick some samples to show how often you communicate when you are apart, or how long you have been communicating. You don't need to show all from the beginning. You don't need to show all the personal messages, just a couple, maybe.
You don't need to send 10s of pictures from all key events. If you have longer relationship, pick one from key events and more from wedding, and engagement and preferably with family involved.
If you have no joint accounts, how do you manage your finance with your spouse? You are the sole breadwinner? Explain that in your cover letter. We did not have joint accounts at the time we sent my application, so I included how we share household expenses. Will and life insurance would be something to consider. Joint tax filing is also good proof.
Focus on quality than quantity.
