Newsletter media kit examples: 12 real kits and what 333 show

Updated November 5, 2026 · by Book a Sponsor

A newsletter media kit shows your list size, how often you send, who reads, your results, your ad formats and your price. Of the 333 newsletters' advertise pages we read on November 4, 2026, 76% state their list size, 39% print an open rate and 24% a click rate.

12 newsletter media kit examples

Twelve real kits from a 449-subscriber list up to 350,000, each a page the newsletter runs itself. Every figure was on the newsletter's own page on November 5, 2026. The price is the asking price for one ad in one issue, as printed; list sizes are the newsletter's own.

Newsletter	List	One ad	Open rate	Clicks	Worth copying
Sales Career Hub	449	$350	46%	9%	A full stat block on a list under 500, plus a 72-hour lead time.
High Signal	2,000	$200	35%	3%	Names its previous sponsors, Twilio and Ahrefs among them, and says what the ad gets: 100 words and an image.
Prompt Teardown	4,418	$99 first ad	36%	5.5%	Says its email stats cover the last 4 weeks, so a sponsor knows how fresh they are.
Loop	5,350	$200	46.8%	1.6%	Lists what to send in one line a sponsor can act on: an image, 120 words and a link.
HeyDesigner	10,250	$380	54.4%	150 to 370 an ad	Gives clicks per sponsorship, email and site combined, as a range rather than one best number.
Military Spouse Newsletter	12,000	$1,000	32%	6%	Sets each rate beside an industry benchmark and gives exact limits: a 60-character headline and 140 words of copy. Its FAQ lower down gives different figures; these come from the rate section.
Climate Insiders	21,000	$700	42%	5%	Prints who reads it, names past sponsors, and compares its cost per click with LinkedIn ads.
The 51st	24,000	$400	66%	2%	A local newsletter that prints pixel sizes for its newsletter ad, plus a 250-word limit and one URL for a sponsored email.
Case Studied	41,400	$1,000	52%	1.5%	Puts its three numbers at the top, with a link straight to the rate card.
.NET Weekly	66,000	$1,400	50%	500 to 1,250 an ad	One short page: stats, audience, previous sponsors such as AWS and Postman, then how it works.
The Saturday Essay	200,000	$2,500	51%	not shown	Under 3,000 characters, with a sentence on who the readers are.
Superpower Daily	350,000	$2,750	42.7%	6%	Gives clicks per campaign and booking rules: up to 90 days ahead, at least two days of lead time.

Check your media kit against newsletters your size

Tick what your kit shows. The check compares it with the kits in your size band and names the gap to close first.

example below: 12,000 subscribers, showing list size, frequency and open rate · change it above · nothing you enter is stored

3 of 9: add ad format and length next

example: a 12,000-subscriber kit against 74 kits this size

Item	Kits this size that show it	Yours
Your list size	100%	Shown
How often you send	91%	Shown
Ad format and length	68%	Missing
A package or multi-issue price	66%	Missing
Who the readers are	61%	Missing
Open rate	51%	Shown
Booking lead time	31%	Missing
Click rate	30%	Missing
Past sponsors or a result	16%	Missing

Ad format and length is the biggest gap: 68% of kits this size show it, and yours doesn't. Word limit, image size, links, where the ad sits. The median kit we read shows 4 of these 9 items, and 4 of 333 show all 9. The list size row reads 100% because a kit needs a stated size to sit in a band.

Most kits say how often they send (83%) and state a list size (76%). Results are rarer: 39% print an open rate, 24% a click rate and 11% name past sponsors or a result. A kit that shows those three stands out, and the median kit shows 4 of the 9 items.

How to build your media kit, in order

Start with the numbers. List size, how often you send, open rate and click rate, dated. Prompt Teardown says its stats cover the last 4 weeks.
Say who reads it. One line on their job or what they buy beats a page of charts. Name the place if you are local.
Print one price per slot. Use the sponsorship calculator for a number and the CPM calculator to check it per 1,000 subscribers.
Spell out the ad. Word limit, image or logo, number of links and where it sits, as Loop and the Military Spouse Newsletter do.
Add proof last. Past sponsors or what an ad got. Only 11% of kits name them in text, so even two names help.
Make booking one step. A deadline and a way to book. The media kit generator lays all of this out on one page, and the proposal template turns it into an offer for one brand.

How we read the kits

On November 4, 2026 we re-read the advertise and media kit pages newsletters publish: 1,055 pages with prices. We left out 414 booking storefronts, because the template decides what they show, and kept each newsletter's own page if it printed a newsletter ad price in US dollars. A newsletter with two pages counts once, on the page that shows the most. That left 333.

The 9 items are text rules, not a person reading each page, and we spot-checked what each rule matched. A rule can miss a figure held in an image or a PDF, and it can count a sentence that only looks like the item. The package rule is the loosest: a word like "discount" in a site menu counts. Past sponsors often sit in logos the rules can't read, so treat that 11% as a floor. Every page here prints a price, so the study doesn't measure how many kits leave prices out.

Questions

What should a newsletter media kit include?

Your price, list size, send frequency, ad format and who reads it, then open rate, click rate and past sponsors if you can show them. Among the 333 kits we read, 83% say how often they send, 76% state their list size, 62% spell out the ad format and 50% say who the readers are.

Do I need an open rate in my media kit?

Most kits leave it out: 39% of the 333 we read print one. It helps when you say how you measured it: Litmus says opens from Apple Mail Privacy Protection users aren't reliable, and that the feature touches roughly 55-60% of opens. It points to clicks as the more reliable number, and only 24% of kits show a click rate.

Should a media kit show prices?

Every kit in this study prints at least one price, because that is how a page got into our read, so the study can't say how many kits hide them. A printed price saves a brand an email. If you don't know yours, the rates page shows what newsletters your size ask.

How long should a newsletter media kit be?

One page is enough. The Saturday Essay offers a $2,500 placement to 200,000 subscribers from a page under 3,000 characters. Put the numbers first and the booking step last.

Is a media kit a PDF or a web page?

A web page is easier: it stays current, a link fits in an email, and a brand can read it on a phone. All twelve examples here are web pages. Offer it when a brand asks, rather than attaching it to a first email.

What can a small newsletter put in a media kit?

Your engagement, who reads you and one clear offer. Sales Career Hub lists 449 subscribers with a 46% open rate and a 9% click rate. At under 5,000 subscribers, 51% of the kits we read print an open rate.
