There was no fraud. The DNC emails show that staffers of the DNC disliked Sanders and strategized how to respond to his criticisms _of the DNC_. At the time those emails were written, Sanders had sued the DNC and had been publicly attacking them. One thing that does not appear in the emails anywhere is any hint that the DNC tried to manipulate the outcome of primaries or caucuses. That's what "election fraud" means.
