In a nutshell... it looks like after 08/2023 the current free tier disappears?There is no explanation of what the impact is on Amazon SES "free tier" users after August 1, 2024.
But it looks like the revised one remains? Their email is rather confusing in nature. They do state that their revised "free tier" allows sending from more sources for the "free" cost from my reading... but they don't state that all free tiers end 08/2024. I have a feeling the revised one will still be active, just with reduced send limits.
