Key takeaways

• Newsletter advertising means paying a newsletter to run your message inside its issue, usually as a primary sponsor, secondary sponsor, classified or dedicated send.
• beehiiv says its publishers sent 28 billion emails to more than 255 million unique readers in 2025¹.
• Published prices run from a $7 classified in a 1,150-reader Substack to $3,680 for a primary slot in the 163,202-subscriber JavaScript Weekly²³.
• One marketplace benchmark prices HR newsletters at $18.47 per 1,000 subscribers and lifestyle lists at $1.22, so niche drives price⁴.
• Ask for unique opens and clicks, since more than half of opens come from Apple Mail Privacy Protection devices and about 1 in 5 clicks are bots⁵⁶.

What newsletter advertising is

Newsletter advertising means paying an email newsletter to put your message in front of its readers. The ad sits inside the issue, next to the writer's own content, and goes out to everyone on the list. Most newsletters label it as sponsored.

It's different from renting an email list. You never get the readers' addresses. The writer sends the issue, the readers already trust it, and your ad borrows some of that trust.

The four common placements

• Primary sponsor. The top slot, often with a logo. TLDR's primary ad sits at the top of the issue, runs up to 100 words and carries 3 calls to action⁷.
• Secondary sponsor. A shorter unit lower down. TLDR's runs up to 50 words with 2 calls to action⁷.
• Classified or quick link. One or two lines and a link near the bottom. TLDR's Quick Links unit is up to 30 words⁷, and the small OpenLampTech newsletter sells a two-sentence classified for $7².
• Dedicated send. A whole email about your brand, sent to the full list. Fewer newsletters offer it, and it usually costs the most of any unit.

Some newsletters cap how many brands appear in one issue. TLDR allows at most 3 advertisers per issue⁷. beehiiv's ad network allows one primary ad and two secondary ads per post⁸. Fewer ads per issue means your ad gets more attention.

Who reads newsletters and why brands buy them now

The audience is large and it opens its mail. beehiiv says publishers on its platform sent 28 billion emails in 2025 and reached more than 255 million unique readers, with open rates of 41% or more¹. TLDR, a tech publisher, says more than 8 million tech workers open its newsletters every week and 22% of its readers are VP level or above⁷.

Big brands are moving in. Substack announced a native sponsorship program on June 15, 2026, with launch partners that included Uber, T-Mobile, Balenciaga, Whatnot, Granola, Polymarket and Yahoo Scout⁹. In October 2026 it added three paid formats. Upgrade lets a brand fund a month of paid access for readers on the free tier. Unlock makes one paid post open to everyone. Masthead ties a brand to a themed collection of writers¹⁰.

Why buyers like the channel

• Targeting by topic. A newsletter about payroll software reaches people who care about payroll software. You pick the audience by picking the writer.
• Trust. Readers chose to get the email. Many open it every issue.
• Clear results. Every ad carries a link, so clicks and sales can be tracked with a tagged URL.

A published result

TLDR reports that Redact paid a 50% lower cost per click than on LinkedIn with placements bought from the publisher⁷. That's publisher-reported, so treat it as proof the channel can work, not as a forecast for you.

What newsletter ads cost

Newsletters price ads in three main ways. Some charge per 1,000 subscribers or per 1,000 opens, called CPM. Some charge per click, called CPC. Many small writers just quote a flat fee per issue.

The last two rows come from one newsletter ad marketplace's Q3 2026 benchmark, built from 12 months of its own campaign data⁴. They show how much niche moves the price. A business reader is worth far more to an advertiser than a general one.

beehiiv's own pricing guide puts most newsletter CPMs between $10 and $75, with specialized B2B newsletters at $50 to $100 or more and broad consumer newsletters closer to $15 to $35¹¹. For a full breakdown by niche and list size, read our guide to newsletter advertising rates and CPM benchmarks.

Quick math

To turn a flat fee into a CPM, divide the price by the list size and multiply by 1,000. JavaScript Weekly's $3,680 primary slot on 163,202 subscribers works out to about $22.55 per 1,000 subscribers³. At its 37% net open rate that's about 60,000 opens, or about $61 per 1,000 opens³.

The direct workflow from brief to renewal in 7 steps

Buying direct means you deal with the writer or the publisher's ad team, not a middleman. Here's the whole job in order.

1. Write a one-page brief. Name your buyer, the offer, the landing page, the budget and the one number that decides success, such as cost per signup.
2. Build a shortlist. Find 20 to 50 newsletters whose readers match your buyer by topic, country and language.
3. Find the contact and ask for rates. Email the writer for the media kit, open dates and price.
4. Vet the numbers. Ask for unique opens and clicks on recent sponsor links, not just list size.
5. Agree terms in writing. Put the date, placement, price, copy approval and reporting in an insertion order.
6. Write the ad and tag the link. Use a tagged URL or a code per newsletter so you can tell them apart.
7. Measure and renew. Compare cost per result across newsletters, then rebook the winners in a package.

Steps 2 and 3 take the most time. Most small newsletters don't sit in any ad network, so you can't buy them from one dashboard. You have to find each writer and email them yourself.

Finding newsletters that fit your buyer

Start from your customer, not from the biggest names. Write down what your best customers read, what job titles they hold and where they live. Then look for newsletters that match.

Where to look

• Your own customers. Ask ten of them which newsletters they open every week. This is the fastest signal you'll get.
• Platform directories. Substack and beehiiv both host public newsletter pages you can browse by topic.
• Competitor ads. Subscribe to newsletters in your space and note who sponsors them. A brand that rebooks the same newsletter is a good sign.
• A contact database. Search newsletters by category, country and language, and see who writes each one.

Small and mid-size lists deserve a real look. beehiiv's guide says even newsletters with a million subscribers rarely see more than 5,000 to 10,000 clicks on a sponsored link¹¹. A tight niche list with a strong open rate can beat a big general one on cost per result.

Our guide on how to find newsletters to sponsor in your niche covers search tactics in more depth.

The slow part is the contact. Many writers don't show an email on their newsletter page, and a contact form may never reach the person who books ads. Doing that by hand for 30 newsletters adds up fast.

Vetting open rates and audience

Every media kit shows a big subscriber count and a strong open rate. Neither tells you enough on its own.

Open rates are inflated. Litmus says more than half of all email opens now happen on devices with Apple Mail Privacy Protection turned on, which inflates reported opens⁵. Clicks have the same problem. Mailchimp's own testing found that roughly 1 in 5 email clicks come from bots, mostly security tools that scan links before a person sees them⁶.

What to ask for

• Unique opens and unique clicks for the last 5 to 10 issues.
• Click rate on recent sponsor links, not just on editorial links.
• Where readers live and what they do for work.
• Two or three past sponsors you could ask about results.

Cooperpress shows what a clear kit looks like. Its Q4 2026 media kit lists each newsletter's subscriber count, its net open rate and the share of subscribers who opened at least one of the last five issues³. Ask every writer for that level of detail. Our guide on how to vet a newsletter open rate has the full checklist.

Sending the first rate request

Keep the first email short. Say who you are, why their readers fit, and what you need to decide. Treat a sponsorship email as commercial email and follow these rules. Use a true subject line, say who you are, include a valid postal address and give a clear way to opt out, then honor opt outs within 10 business days¹².

Subject line
Sponsoring [Newsletter Name] in [Month]

Hi [First Name],

I run marketing at [Brand]. Your issue on [specific topic] was a great fit for us. [Product] helps [audience] [result], and your readers look a lot like our customers.

We'd like to book a sponsor slot in [Month]. Could you send your media kit or rate card? If you don't have one, these four things are all I need.

1. Unique opens and clicks for the last few issues
2. A rough split of where readers live and what they do
3. Open dates in the next 2 to 3 months
4. Your price per placement and any multi-issue rate

Thanks,
[Your Name]
[Title], [Brand], [website]
[Company, postal address]
Not a fit? Reply no and I won't email again.

Send it to 20 or more newsletters at once so you can compare quotes. Our newsletter sponsorship email template page has follow ups and versions for packages and dedicated sends.

Contracts, ad copy and disclosure

A short insertion order protects both sides. It should list the newsletter, the send date, the placement, the price, the copy deadline, who approves the final copy, and what reporting you'll get after the send. Add what happens if the issue goes out late or the link breaks.

Cooperpress is a good model. It asks for material by the Friday before the send, sends a visual proof first, needs one week's notice for changes and sends a click report after the campaign³.

Writing the ad

• Lead with one benefit the reader cares about, in the writer's tone.
• Give one clear action and one link.
• Let the writer edit for voice. Readers trust the writer, not you.
• Respect the unit's limits. A 30-word quick link and a 100-word primary ad need different copy⁷.

Label it as an ad

The FTC says an ad must not suggest it's anything other than an ad, and disclosures are judged by whether readers actually recognize the ad¹³. Most newsletters already label sponsor slots. OpenLampTech, for one, marks all paid content as sponsored². Don't ask a writer to drop the label.

Tracking results

Give every newsletter its own tagged link. Google Analytics reads campaign URL parameters such as utm_source, utm_medium and utm_campaign, so you can see which newsletter sent each visit¹⁴. A simple pattern is utm_source set to the newsletter name, utm_medium set to newsletter and utm_campaign set to the month.

Add a second signal. A unique discount code per newsletter catches readers who type your address instead of clicking. A one-question "how did you hear about us" box on your signup form catches the rest.

Judge on cost per result

Clicks alone can mislead you, since some are bots⁶. Divide what you paid by signups, trials or sales from each newsletter. Then rebook the cheapest ones, drop the rest, and ask the winners for a package rate.

Direct vs ad networks vs Substack and beehiiv

You don't have to buy every newsletter one by one. Here are the main routes and what each gives up.

beehiiv's network only places ads in newsletters sent through beehiiv⁸, and Substack's program only covers Substack writers¹⁰. Many good newsletters run on other tools. Buying direct is the only route that reaches all of them.

Find and email the right newsletters today

The step that eats the most time is finding newsletters that fit and reaching the person who writes them. That's the job Media List does.

• Find newsletters. Media List has 28,000+ newsletters you can email. Search by category, country and language.
• See the contact. Emails unlock from your plan's allowance, no bot checks.
• Save a shortlist. Keep your picks in a saved list for each campaign.
• Ask for rates. On Professional, send the rate request from built-in email campaigns using your own mailbox.

Media List doesn't hold rates, open rates or subscriber counts for newsletters, and it has no subscriber filter. You get who to contact and how to reach them, then the writer's media kit tells you the rest.

Basic at $99 a month covers search, saved lists and exports. Built-in email campaigns come with Professional at $399 a month. Start with a 3-day trial. It's $0 today, and you can cancel anytime. Compare plans on the pricing page.

Questions, answered

What is newsletter advertising?

Newsletter advertising is paying an email newsletter to include your message in its issue. The writer sends it to their own readers, usually labeled as sponsored. Common formats are a primary sponsor slot, a secondary slot, a classified line and a dedicated send.

How much do newsletter ads cost?

Published prices range from $7 for a classified in a 1,150-reader niche newsletter to $3,680 for a primary slot in JavaScript Weekly, which has 163,202 subscribers. beehiiv's guide puts most CPMs between $10 and $75, and higher for specialized B2B lists.

How do I advertise in a newsletter?

Write a short brief, build a shortlist of newsletters that match your buyer, and email each writer for a media kit and rates. Vet unique opens and clicks, agree terms in writing, tag each link, and rebook the newsletters with the lowest cost per result.

Are newsletter ads worth it?

They can be for brands with a clear niche buyer. TLDR reports that Redact paid a 50% lower cost per click than on LinkedIn. Results vary, so start with a small test across several newsletters and judge each on cost per result.

What is the difference between a newsletter ad network and buying direct?

An ad network such as beehiiv's places your ad across many newsletters on one platform and bills per open or per click. Buying direct means you pick each newsletter and deal with the writer, which reaches newsletters on any platform and gives you full control.

Do newsletter ads need to say sponsored?

Yes, readers should be able to tell it's an ad. The FTC says ads must not suggest they're anything other than ads, and most newsletters label sponsor slots for that reason.

What should I ask a newsletter before I buy?

Ask for unique opens and unique clicks for the last several issues, click rates on past sponsor links, where readers live and what they do, and two or three past sponsors. Subscriber count alone doesn't tell you enough.
