> But...several full-time jobs? I think it depends on how important delivery is to your business. If your business team expects near 100% delivery and they want all the tracking features that give them insight into their promotional campaigns, then running email promotions on your own is quite a steep hill to climb. I run my own MTA on my own domain and only use it for verification purposes and I still have to fight with the free email providers every few weeks. It's definitely not a full-time job but I also have the joy of just not caring if a user doesn't get an email from my system. A agree with you somewhat that people reach for mass mail services too quickly sometimes but I also understand the perspective of engineers who have things like deadlines and other work to do where if I have the choice of working on truly new things to help grow the business I work for or handling email logistics, I know where I will point the my company.
