I’ve read this a lot, often as a counter argument to running your own mail servers, and I believe it to be mostly FUD. I run a small SaaS and it sends out quite a lot of notification emails to customers (they are paying me for these emails, they aren’t spam or newsletters). I was originally using SendGrid but their deliverability rates were pretty bad and I was about to hit a ceiling for my plan, which would meant the monthly cost would more than double, which was unaffordable for me. I decided to try setting up my own mail server. Everyone said don’t do it, you emails won’t be delivered, it’s too much work, etc. I setup a VPS with OVH as I’ve heard their policies regarding email spam are pretty strict (I contacted them before to clarify - if they find out you are spamming they cut your off ASAP to protect their other customers). The IP I got was actually on one blacklist, but I got that resolved in a few days. The deliverability rate was better than SendGrid and it was costing me 1/10th of the price. One thing that I would assume helped is the domain had already been in use for a few years, and I setup proper DKIM and SPF records. The server has been running for a year and a half now, and the only bounces I get are due to invalid or suspended email accounts. Most of my customers are small to medium sized businesses, a lot of which run their own Exchange servers - with SendGrid those were usually the ones who were bouncing my mail due to being on a blacklist. Now admittedly just being accepted doesn’t mean it is ending up in a users inbox, but I haven’t had any complaints from paying customers.
