Email sending is a largely efficient market, and SES is the cheapest sender.
Thus, the SES IP pools have the worst IP reputations among all the SMTP-based senders. I would never use them (or an ESP that sends with them) in a million years.
The reason why cheap = bad in email is because Spammers have the lowest conversion rates of all senders (their emails are always untargeted), so price is their number 1 consideration.
You can cheap out elsewhere in your stack. But never cheap out on email — especially if you’re not sending high volume enough for a dedicated IP.
