E-mail deliverability is one of my top concerns, and I don't trust myself to handle it as well or better than the experts working on Google's email platform. SPF, DKIM, DMARC etc. are fairly basic concepts to learn but I wouldn't call myself an expert in their implementation by any stretch of the imagination. That's to say nothing of the non-standard oddities that pop up with deliverability to certain networks, ISPs, etc. that require ongoing attention and that I don't want to have to deal with.
If you are willing to deal with the occasional hiccup and learn about the odd issue as it comes up, the above is not really a huge concern. But if you are like me and would give up a lot to avoid the horror of realizing some email(s) have not gone through at the worst possible time (i.e. on the day of an important business deadline, with no time to troubleshoot the root cause), entrusting your mail to a platform like Google or FastMail is a must.
The "tinkerer" aspect of me would like to run my own mail server and would enjoy knowing that it's fully within my control and configured exactly the way I want it. The pragmatist in me says, "No way!"
