Two step ladders, one date
Postmark publishes a ladder of inclusions, and each inclusion exists on Basic, Pro and Platform. The Postmark cell is the inclusion whose total is smaller than the other inclusions that still cover the count. Past the largest inclusion, that total adds the per-thousand rate the page prints for the step. Resend's cells use the same rule on Free, Pro and Scale: a plan with no stated rate past its inclusion does not cover a larger count. Both notes, fetched 2026-11-09, are printed once under the table. AgentiSend's yearly term is 40% off the monthly price of the rung that holds the count.
The column headed and AgentiSend is not a third party fetched that day. It is the tier table.
