Receiving email is easy. Sending it is much harder. One of the things that is the most frustrating is that if you end up on a blacklist, or a large provider decides independently not to trust you, it's often completely silent when it blackholes all your outbound emails to that service. I've just moved over to a hybrid of hosting my own MX servers for incoming email, and forwarding all my outgoing emails to an email-as-a-service provider for outgoing messages. Their trusted IPs usually help delivery, and they're actively paid by their users to have employees making sure that their IP ranges are whitelisted.
