Hello @MarketerL9890 ,

Based on the overwhelming number of your bounces being blocked, I'd deduce the source of your issue is related to your (lack of) authentication setup in your account. 

If you're sending from a private domain, then you'll want to setup your account for self-authentication. Otherwise, some networks and security will see your email claiming to come from you, but is actually coming from our servers, and treat it like it's a spoof / spam. By setting up self-authentication, you mark us sending your emails as officially approved, and to be treated as though they're coming directly from you.

If you'd like further insight and troubleshooting on your delivery, or guidance on setting up self-authentication beyond what's in the linked article, I'd recommend speaking with our Delivery team directly.
