Disagree here. The sendgrid, mailchimp, postmark of the world are in the business of sending emails. They have their dedicated IPs and handle deliverability, anti spam, and whatnot with email providers like Gmail.

SES is an email sending infrastructure tool. That's not the same.

IMO equating SES with an email company is like saying home depot is a contractor because they sell hammers and lumber. It gives you the tools to be able to build stuff but it's not the same as a construction company.
