Long gone are the days when you can just set up an email server and start sending messages. Because of the proliferation of spam, it has become harder and harder to send mail with any assurance it will be received (that's why I switched over to Mailchimp, and then later to Mailgun, to send out OLDaily). This article is from Postmark, which I may or may not use in the future. Anyhow, to successfully send an email today, you must authenticate yourself as sender in three ways (DKIM, SPF, and DMARC), keep your spam complaint rate below 3%, support 1-click unsubscribe, support RFC 5322 compliance, PTR records, and rDNS, make sure your server IP addresses have reverse DNS records, and use a TLS connection to send email. Even using Mailgun, I've had to learn how to do most of this. But you can see why people flocked to a platform like Substack to send their newsletters (unfortunately).
