Thanks for your feedback! The main reason for pricing is storing all the past emails and the architecture to store and process future emails. If you compare the pricing, the overall costs with SES + Pendable should still be far lower than other platforms for comparable sending limits.
I don't really care about storing past emails and I'm pretty sure that lots of others don't either because your competition doesn't seem to offer it in a lot of cases.
For those like myself, storage is just an unnecessary expense.
We will surely take that into account and carve it as an add-on. (Postmark did the same recently with their retention-add-on)
We are early in the product phase so feedback like yours is very valuable!
Thanks again
