What a media kit for a small newsletter is, and what goes in one

A local business owner replies to a small newsletter's sponsorship pitch with one line: send over your media kit. The publisher freezes. They have never made one, they are not sure what it is, and they suspect the answer involves a designer and money they do not want to spend. The honest answer is that a media kit is a short page that tells a potential advertiser who reads you, how engaged they are, and what you charge for an ad.

What matters is what goes on the page, where the numbers come from, and how to present them so an advertiser can check them.

What goes on the page

Four components make up the core. First, audience numbers: your subscriber count and where those readers live or work. Second, demographics: who the readers are in terms an advertiser cares about, such as whether they are homeowners, parents or business owners. Third, engagement: how many people open the newsletter and click, pulled from your email platform. Fourth, what you sell: the ad formats you offer, such as a sponsored slot or a dedicated send.

Around that core sit the working details. A one or two sentence description of the newsletter, the send schedule, the contact for bookings, and any rules you have, like a limit on ad slots per issue or the categories you will not accept. A one-page document, or a short page on your site, is a normal format for a small newsletter. One common approach is to build it in a document editor and export it as a PDF, or publish it as a plain page. Longer kits exist at larger publications. For a small newsletter, the one-page version does the job, because everything on it is information the advertiser asked for.

On rates, you have two options and both are standard practice. You can publish prices next to each format, or you can list the formats and quote prices on request. Pick one and be consistent. The one thing to avoid is a page that names no formats at all, because then the advertiser cannot tell what they are buying. Whether the number is printed or emailed is a business decision, not a requirement of the format.

The demographics are where small kits go weak

The weak point in many small-publisher media kits is the demographics. It is tempting to write something like readers are affluent local professionals and leave it there. That sentence has a source problem: it is the publisher's guess, and an advertiser checking the kit has no way to see where it came from. A claim carries more weight when the publisher collected it from readers directly, in the readers' own words, and says how.

One way to get those numbers: ask at signup

A survey at signup is one way to collect them. Instead of sending a poll to the whole list later, the questions land right after someone subscribes. Ask a handful of short questions about where they live, whether they own or rent, whether they have children, whether they own a business, and what they are interested in. The answers become the demographic section of the media kit.

Report the method, and keep the respondents separate from the list

One distinction does most of the credibility work: the people who answered a signup survey are not your entire list. They are the subset that subscribed during the survey window and chose to answer. Every number from the survey describes those respondents, and the kit should say so plainly.

A demographic number means more when the advertiser can see where it came from. Three details do that work. Say the sample size: how many readers answered the questions. Say the collection period: the dates or the window during which the survey ran. Say something about representativeness: whether the readers who answered look like the list as a whole, or whether the sample skews toward the newest subscribers.

To see the difference, imagine a kit that reads 68 percent of surveyed respondents own their home, based on 214 responses collected between March and May. That is a hypothetical example, not a real figure, but the shape of it is the point. The phrase surveyed respondents does the honest work: it names the group the number covers. If the sample is small or new-subscriber-heavy, state that plainly. A number with a stated method is a fact an advertiser can evaluate. A number without one is a claim they have to take or leave.

A tool for the survey part

One product built for this exact moment is greetform. It replaces the plain thank-you page after a signup with a short survey, using conditional logic, meaning each answer picks the next question. Every answer syncs to the subscriber record in Beehiiv, ActiveCampaign or Mailchimp as a field to segment on, so the answers stay attached to real subscribers instead of sitting in a separate report. It works alongside the email platform, nothing migrates, and there is a free forever plan with no card needed. The app is at app.greetform.com.

Who this is for, and who it is not for

This is for any publisher who has been asked for a media kit, or expects to be, and does not want to improvise one in an email thread. A newsletter with a modest list can have one. The kit answers questions an advertiser already asked, and a focused list of local readers answers them better than a large vague one.

Publishers with no interest in sponsorship or advertising can skip it. If the newsletter earns from subscriptions or products and no advertiser will ever email you, the kit is busywork. The kit also supports a pitch rather than replacing it. The pitch starts the conversation; the media kit is the document the advertiser reads before signing.
