Hello @Ironcoop ,
Deliverability can have a lot of variables, from elements on our side, on your side, on the recipient's side, and in their email system company's side. I'd strongly advise setting your account up for self-authentication since you're sending using an address with your own, unique domain. With all the delivery gatekeeping and anti-spam/malware safeguards in place, it's necessary for businesses using an ESP to have this in place.
If you're wanting more in-depth, specialized insight on your current deliverability, it'd be worth speaking with one of our Deliverability agents.
