Newsletter Directory and Contact List for Advertisers

beehiiv's ad network only places ads in newsletters sent through beehiiv¹. Substack's sponsorship team matches brands with writers by hand, and its Creator Kits are private². Both are useful, but neither is a list of newsletters you can approach. If you want to pick the newsletters yourself and talk to the writers, you need a newsletter directory with contact emails.

This page explains what a newsletter directory for advertisers should show, how it compares with ad networks, marketplaces and platform programs, which fields matter, and how to go from a search by niche and country to a sent rate request.

Key takeaways

• A newsletter directory for advertisers lists newsletters with their topic, country, language and a contact email for the writer, so brands can buy sponsorships directly.
• beehiiv's ad network is open only to newsletters sent through beehiiv, and publishers there choose which advertiser offers to run.
• Substack's Creator Kits are visible only to brands its team has connected with a writer, and the team does the matching by hand.
• Open rates and prices come from the writer, so a directory gets you to the person who has them rather than replacing the media kit.
• CAN-SPAM applies to business email, and each email in violation can cost up to $53,088, so every outreach email needs a postal address and an opt-out.

What a newsletter directory should show an advertiser

Most newsletter directories were built for readers. They help people find something to subscribe to. An advertiser needs something else. You need to find newsletters your buyers read, and then reach the person who sells the ads.

So a newsletter directory for advertisers has two jobs.

• Find. Narrow thousands of newsletters to the few dozen that fit your buyer, by topic, country and language.
• Reach. Give you an email for the writer or business contact, so you can ask for rates and dates.

A list that only does the first job is a reading list. A spreadsheet of emails with no topics is a mess. You need both in one place, plus a way to save your shortlist and send the outreach.

Why direct contact matters

The supply is spread out. Substack had more than 50,000 moneymaking publications in March 2025³. beehiiv reports 65,000+ newsletters⁴. Publishers like TLDR run 14 newsletters of their own and build a custom proposal for each advertiser⁵. Many independent writers sell their own ads and simply ask sponsors to email them, like OpenLampTech does⁶. If you want those newsletters, you deal with the writer.

Who uses one

• DTC brands testing classifieds in ten niche newsletters before they scale.
• B2B and SaaS teams looking for small newsletters that reach one job title.
• Agencies building newsletter plans for several clients, one saved list per client.
• Publicists pitching the same writers for coverage and sometimes paid placements.

Platform directories vs ad networks vs a contact database

There are several ways to reach newsletters as an advertiser. Here's how they compare.

Notice the pattern. Networks and programs keep the writer at arm's length. That's how they work. If you want to pick a newsletter and email the writer about a sponsored issue, you need the writer's email.

None of these is wrong. Many brands use a network for reach and a directory for niche newsletters. Our newsletter advertising guide covers when to use each.

Why no ad network is a full directory

It helps to see exactly where each network's edges are.

beehiiv's ad network

• It's available to publishers on the Lite plan or above who are actively sending on beehiiv¹.
• It only covers newsletters sent through beehiiv, not other email tools¹.
• It's non-exclusive, so publishers can also sell direct sponsorships¹.
• Publishers see a set of personalized offers and choose which ones to run¹.

beehiiv says creators have earned $37,872,727 through it so far¹. It's a real channel. But you don't choose the newsletter the way you would by email, and you don't get to know the writer.

Substack's program

• Substack announced it on June 15, 2026, with launch partners such as Uber, T-Mobile and Balenciaga⁷.
• Creator Kits are available to Substack bestsellers and publications with at least 100 paid subscribers².
• Kits aren't public. Only brands in the program that Substack's team has connected with a writer can see them².
• Substack hasn't published pricing, revenue splits or minimum budgets².

Ad marketplaces

Marketplaces list the newsletters that signed up. One newsletter ad marketplace says verified newsletters sync their email platform, so list size and engagement come from the sending system⁸. That's useful data, but only for members.

So the newsletters outside these programs, often the small, niche ones with your exact buyer, are reachable only by email. Finding each one and the right contact, site by site, is the slow part.

The fields that matter

When you compare newsletter directories, check for these fields. Each one saves you a step.

What a directory can't give you

Subscriber counts, opens, clicks and prices are the writer's own data. They share them in a media kit or a reply. Treat any outside estimate as a guess. Opens are also harder to trust than they look. Apple's Mail Privacy Protection prevents senders from seeing if you've opened their email⁹, and Litmus says over 50% of opens happen on devices with it turned on¹⁰. Ask for clicks on recent sponsor links too.

Our guides to the newsletter media kit and vetting a newsletter's open rate show what to ask for.

How to search by niche and country

Here's how a search works in practice. Say you sell a meal kit in the US.

1. Pick the main category. Food, with country set to United States and language set to English.
2. Add nearby categories. Health, family and parenting newsletters reach the same buyer from another angle.
3. Use keywords. Try words your buyer would use, such as recipes, meal prep or weeknight dinners.
4. Open a few results. Read the last two or three issues. Would your buyer read this?
5. Save the good ones. Add each fit to a saved list named for the campaign.

Aim for a long list of 50 to 100 and a shortlist of about 20. Our guide on how to find newsletters to sponsor walks through how to cut the list.

Think local

If you sell in one city or region, local newsletters can be a great fit. beehiiv says neighborhood and regional newsletters often enjoy open rates well above 50%⁴. Filter by country, then search the city or region by keyword.

Think across languages

If you sell in Spanish, German or French, filter by language too. Your ad and landing page should be in the reader's language.

Saving and exporting a shortlist

Once you have your list, keep it in one place so the whole team can work from it.

• Name lists by campaign. For example, "Meal kit, US food newsletters, spring test".
• Keep one list per client if you're an agency.
• Add notes as writers reply. Price, open dates, opens and clicks, so you can compare offers side by side.
• Export when you need to. Take the list into a spreadsheet or your CRM within your plan's monthly allowance.

Vet before you pay

Saving a newsletter isn't the same as booking it. Before you pay, ask the writer for recent sponsor clicks and a sample issue. PostHog, the product analytics company, wrote in its handbook that it cared more about click-through rate than list size, and asked partners for their average click-through rate¹¹. That's a good habit to copy.

Sending outreach from built-in campaigns

With your shortlist saved, the next step is the rate request. On Media List Professional, you can send it to the whole list from built-in email campaigns, from your own mailbox, with the writer's first name and newsletter name filled in. Professional includes 5 active campaigns and 1 sending mailbox.

A rate request that gets replies

Hi [First name], I read [newsletter name] and your readers look a lot like our customers, [one-line buyer]. We'd like to sponsor an issue in [month]. Could you send your sponsor options, prices, recent opens and sponsor clicks, and open dates?

Thanks, [Your name], [Title], [Company, postal address]

Not a fit? Reply no and I won't email again.

Follow email law

Treat a sponsorship email as commercial email and follow these rules. The FTC's CAN-SPAM guide says to use honest header information and subject lines, include a valid postal address, tell people how to opt out and honor opt-outs promptly. The law makes no exception for business-to-business email, and each email in violation can cost up to $53,088¹².

Send one follow-up after about a week if there's no reply. For more versions of this email, see our newsletter sponsorship email template.

Directory vs doing it by hand

You can build a newsletter list by hand. Here's what that looks like for 100 newsletters.

• Search each platform separately for each topic.
• Open each newsletter's site and read a few issues.
• Look for an About page, a sponsor page or a business email.
• Copy the name, topic, country and email into a spreadsheet.
• Then write and send each email from your inbox, one at a time.

Say each newsletter takes about five minutes to find, check and log. That's over eight hours for 100, before you send a single email. A directory cuts the find and log steps to one search, so your time goes into reading issues and talking to writers.

The same holds for podcasts. Our podcast database for advertisers guide covers the podcast version of this job.

Three ways advertisers use a newsletter directory

1. A classified test across ten newsletters

A DTC brand picks ten newsletters in its category and buys one short text ad in each. Classifieds are cheap enough for this. DigestThis.news charges $150 for a 150-character classified, and Ann Friedman Weekly charges $155¹³¹⁴. Ten ads at about $150 is $1,500. The directory supplies the ten writers and their emails. The tracked links show which audiences respond. Our guide to newsletter classified ads covers the test step by step.

2. B2B reach by job title

A software company wants product managers, or IT leads, or founders. Big publishers sell this kind of reach through their own sales teams. TLDR, for example, runs separate editions such as TLDR Product with 410,000 subscribers and TLDR IT with 590,000, and builds a custom proposal for each advertiser⁵. A directory adds the smaller newsletters written for the same job titles, which often sell their own ads and answer email directly.

3. An agency planning for several clients

An agency runs newsletter plans for a meal kit, a fintech app and a B2B tool at once. It keeps one saved list per client, filtered by that client's category, country and language, and notes each writer's price and dates as replies come in. When a client asks for a second wave, the list is already there.

In all three cases the directory does the same job. It turns "which newsletters?" into a list of writers you can email, so the team spends its time on reading issues, negotiating and tracking results.

Your job is to pick the newsletters your buyer reads, reach each writer and get rates back before the campaign date. Media List is a contact database built for that, so you go from "which newsletters?" to "rate request sent" in one sitting.

• Find the fits. Media List has 28,000+ newsletters you can email. Filter by category, country and language, and search by keyword.

Questions, answered

What is a newsletter directory?

A newsletter directory is a searchable list of newsletters with details such as topic, country and language. Directories built for advertisers also include a contact email for the writer, so brands can ask about sponsorships directly.

Is there a database of newsletters with contact emails?

Yes. Contact databases like Media List list newsletters with a writer or business contact you can email, searchable by category, country and language. Emails unlock from your plan's allowance.

Does the beehiiv ad network include every newsletter?

No. It only covers newsletters sent through beehiiv on the Lite plan or above, and publishers choose which offers to run¹. Newsletters on other platforms aren't in it.

How do I contact a Substack writer about a sponsorship?

Check the newsletter's About page or sponsor page for a business email, or use a contact database. Substack also runs its own sponsorship program, where its team matches brands with writers by hand².

Does a newsletter directory show open rates and prices?

A contact database usually doesn't. Opens, clicks and prices are the writer's own data, so ask for them in your first email and check sponsor clicks, not just opens⁹.

How much does a newsletter contact database cost?

Media List plans start at $99 a month for search, saved lists and exports, and Professional at $399 a month adds built-in email campaigns. There's a 3-day trial with $0 due today.
