Share is the part of them that ran a paid sponsor ad in that time. The monetization guide splits the larger sizes; this page cuts the smallest row in four.

What a small list can charge

68 newsletters under 5,000 subscribers print a main-slot price. They list a median $150 for one placement in one issue, and the middle half list $95 to $263, on a median list of 2,150 subscribers (printed prices, read 29 September 2026). Per reader that is about $70 per 1,000 subscribers, the highest of any size: a small list sells at a higher price per reader and a lower price per issue.

What the numbers do and don't show

They show that brands buy ads in small newsletters. They don't show how many slots those newsletters sold, at what price, or how long they waited for the first sponsor.
The shares are a floor. They count only ads printed in the public text of an issue, so a newsletter that sells through paid-only posts or a network that prints no label looks like one with no ads. Detection also differs by email platform.
A flat line under 5,000 doesn't mean size stops mattering. The monetization guide shows the share rising again from 5,000 up to 100,000 and more, and every price in the rates table rises with size.
List sizes are counts the newsletter or its platform reports. Modeled estimates are left out, which leaves 7,775 of 12,308 newsletters in the table.
