I'm looking for recommendations on services to send transactional emails through API or SMTP. What do you like most about the service you use, and is there anything you feel is missing? I'm hoping to gather feedback from real users as I work on my own solution.

We've tested several options. Despite the low cost, SES had issues with blacklisted IPs and lackluster support. Mailgun was similarly problematic with their shared and dedicated IPs. Right now, we're with SendGrid since their pricing works for us and the support has been solid.
I've been using AWS SES. It's affordable and does the job well for me without needing any fancy interface. I just need the SMTP endpoint to get my transactional emails sent out right.
I've tried out Postmark, SendGrid, and Mailgun. Personally, I prefer Postmark for its speed and reliability. It has a clean API that's super fast, but I find that many tools struggle with good template management and make testing a bit of a hassle.
I have a similar experience—Postmark is definitely my go-to these days.
That's interesting! How do you check if your IPs are blacklisted?
