From my past experience with AWS SES, it requires a bit more development to handle bounces, spam, etc. Perhaps at $previousjob, we did not have the resources to handle this development time.
Personally, I prefer Postmark. Their onboarding, support, and pricing is excellent. The interface is good and decent integrations.
Budibase also has a more comprehensive UI builder, internal database, forms, configurable onboarding, free SSO, Kubernetes support, a cloud platform, off the top of my head.
