An included address against a PDF step
Mailgun's note under the table, fetched 2026-11-09, gives Free a daily cap and no monthly inclusion, so Free holds a count only when the count fits in the shortest month the price function allows at that cap. The smallest volume in the table does not fit, which is why that cell is Basic rather than Free. The dedicated-IP sentence in that note is the dedicated-IP cell: the first address is included on the rows the note names, and another address has the price the note states.
SendGrid's cells are the PDF steps. There is no monthly row at no charge. The day-cap offer in SendGrid's note stays outside the price ladder. The same note does not state a dedicated IP price, so the SendGrid cell for that row is the absence, not a number carried over from a different page.
Neither provider's pricing note states a retention period or a DKIM key length. Both cells say that, with the URL and the date, rather than a day count from another write-up.
