I've been using Postmark for my personal email domain. I was using Sparkpost, but I had problems. Specifically, some email help desks seemed to reject the emails - so I was unable to respond to some inquiries. Many friends reported that my emails were going to Spam, too. With Postmark, I've had zero deliverability issues. I recommend monitoring DMARC closely to ensure deliverability. I use this free tool from Postmark: https://dmarc.postmarkapp.com/ https://dmarc.postmarkapp.com/
