Managed sponsorships in author newsletters for brands

Newsletters beyond the public directory

We connect you with creators who aren't listed anywhere public. You choose based on audience fit, not on who promotes themselves the most.

We know what works in your sector

We analyze which newsletters perform well with banners, mentions or reviews, and which have the best CTR for brands like yours.

One invoice, zero hassle

We search, negotiate, write the ad, coordinate and report. You approve the copy and review results. You receive a single invoice for the entire campaign.

Why sponsor author newsletters

Author newsletters have the highest attention rates in digital advertising today. Real audiences who chose to subscribe, no cold clicks.

30-50%
Average open rate

Compared to <1% average CTR on Meta Ads or display. Your brand appears where the audience is already reading with attention.

3-8%
CTR on opens for mentions

Clicks over the people who opened the email, not over the total subscriber count. When a newsletter recommends your brand, its audience clicks.

Audiences who subscribed by choice

Data from our campaigns. See a real case →

Sponsoring a newsletter is the difference between interrupting someone with an ad and appearing as a recommendation from someone they already trust.

We reach any market, in any language

Your customers might be in London, Mexico City or Berlin. We find newsletters with a real audience wherever they are, in the language they read. This is how we decide where your brand appears:

Country and language

Any country and any language. We check where the audience is using each newsletter's stats.

Topic

Over 60 categories, so you show up where people already talk about what you do.

Age and gender

Based on the audience data each newsletter shares with us.

Size and opens

Subscribers and open rate, to match reach to your budget.

Guaranteed

The impacts you book, counted as real opens of each send. If we fall short, we run your ad in more newsletters until the number is reached. How we measure it

Depends on more

Clicks, subscribers and sales. Your offer, the creative and the timing all play a part, so we pick matching newsletters and review every send.

How we measure and guarantee impacts

The guarantee is met with real opens, not estimates. Here's how it works:

What an impact is

One open of the edition your ad appears in. In the proposal we give you an estimate per newsletter (subscribers × its average open rate), but only real opens count towards the guarantee.

How we measure it

Seven days after each send we collect the opens from each newsletter's platform stats (Substack, Beehiiv, MailerLite…). The final report includes screenshots of that data alongside the clicks on your tracking link.

If we fall short

If total real opens come in below your package minimum (for example, 6,000 in the $1,000 package), we run your ad in more matching newsletters, at no cost, until the impacts you booked are reached.

Why not just put it into Meta, Google or LinkedIn Ads?

Per impression, social and search ads usually look cheaper. But you're not buying the same thing: the difference shows up when you compare attention and clicks, not impressions.

Social and search ads Independent newsletters
What you buy Impressions: the ad scrolls past the screen Real opens of an email the reader chose to receive
Attention A few seconds in the feed or among results, next to other ads Inside the content being read
Who recommends it Your brand, as an ad A writer the audience already trusts
Clicks Average CTR below 1% on social and display 3-8% CTR: $2 to $5 per click
Traffic quality Invalid traffic to filter and ads hidden by ad blockers Opt-in subscribers, clicks measured with your link and an email ad blockers don't hide
Learning phase Weeks of budget until the algorithm settles The audience is already segmented by topic
Best used for Scaling volume, retargeting and capturing people already searching for you Building trust and reaching niches

Frequently asked questions about newsletter sponsorships

What do managed campaigns include?

We handle the entire process: finding suitable newsletters, contacting creators, negotiating and managing deals, writing the ad for each newsletter, coordinating the schedule and delivering metrics.

You just approve the budget, sign off the copy and review the results. This saves you time and avoids operational tasks.

What is an author newsletter and what does it mean to sponsor one?

An author newsletter is a digital publication that arrives by email to subscribers interested in a specific topic. It's created by journalists, experts or independent professionals with their own editorial content.

Sponsoring a newsletter means a brand supports that publication (usually financially) in exchange for visibility: whether through a banner, a mention or a recommendation within the content.

How much do managed campaigns cost?

We work with fixed packages starting at $1,000 (6,000-7,000 real impacts), then $2,500 and $5,000. The price includes everything: newsletter research, negotiation with each creator, ad copywriting, calendar coordination, a single invoice for the total and a final metrics report.

You can book it as a one-off campaign or as ongoing management, month to month with no lock-in. If you already know which specific newsletter you want to sponsor, get in touch and we'll guide you to the option that best fits.

Is it better to sponsor newsletters or advertise on Meta Ads?

It depends on the goal, and the most profitable approach is usually to combine both. Meta Ads is cheaper per impression and works for scaling volume and retargeting. Newsletter sponsorships have a higher CPM, but you're buying something else: real opens of an email the reader chose to receive, with your brand inside the content and recommended by a writer they trust.

That's why the fair comparison isn't cost per thousand impressions but cost per click and per attention. On Meta the average CTR is below 1%; newsletter mentions run at around 3-8%, which in our packages means $2 to $5 per click, with traffic that arrives with the recommendation already made. On top of that, ad blockers don't hide email, subscribers signed up by choice, you measure clicks with your own tracking link and you don't pay for a learning phase: the audience is already segmented by topic.

Our recommendation: keep Meta for scale and use newsletters to build trust and reach niches where social ads don't work.

In which countries and languages can you run newsletter sponsorship campaigns?

In any country and in any language: we find newsletters with an audience wherever your customers are.

To pick them we target by topic (over 60 categories), audience language and country, checked against each newsletter's stats, age and gender, based on the data each newsletter shares with us when they have it, and size (subscribers and open rate). You'll see this data for each newsletter in the proposal before paying anything.

I'm an agency, what advantages do I get from using Niusleters over other platforms?

With Niusleters' managed campaigns you don't need to manage anything directly. Just tell us your brands' or clients' goals, and we take care of the rest: finding suitable newsletters, contacting creators, negotiating conditions, writing the ads and coordinating the sponsorship.

You receive a fixed budget, no surprises, and a final report with metrics to evaluate the impact. It's an ideal solution if you want to save time and ensure well-managed collaborations from first contact to publication.

How do I know the campaign will work before paying?

Before you accept the budget, we send you a proposal including: selected newsletters, real subscriber counts for each, expected impacts and estimated CTR based on previous campaigns in that sector. The specific selection of newsletters and categories is subject to their availability at the time of the campaign and may change; what we guarantee is the number of impacts. You know what to expect before investing a single euro. Nothing gets published without your approval.

Who writes and designs the ad?

We do, and it's included in the price. After payment you tell us where you want to send the traffic, whether there's an offer or code and anything we shouldn't say about your brand, and you send us your logo and images. With that we write the copy and design the banner for each newsletter, adapted to its format (mention, banner, review or link) and to its creator's tone, which is what works best in this channel.

We send you all the ads together, each with its own UTM link so you can measure results. We do as many rounds of revisions as you need until you approve them. If you'd rather use your own copy or creative, you can.

What is ongoing management?

It's how you hand your newsletter channel over to us completely. Every month we pick newsletters, write the ads and send you the report. You send back your conversion data (sign-ups, customers or sales from each link) and we use it to decide which newsletters to repeat, which to swap and which messages work best.

Since from month two we're no longer starting from scratch, you get 15% more impacts for the same price.

Is it better to sponsor newsletters or invest in Google Ads?

They do different jobs and work best together. Google Ads captures demand that already exists: your ad shows up when someone searches for your product, and you pay per click in an auction that keeps getting pricier in competitive sectors. Newsletter sponsorships create demand: you reach people who aren't searching for you yet, inside content they chose to read and with a recommendation from a writer they trust.

That's why many brands use newsletters to get known in a niche and Google to capture those searches later. A practical way to decide: compare our packages' estimated cost per click, $2 to $5, with what you pay for your keywords today.

Should I sponsor newsletters or advertise on LinkedIn Ads?

For B2B brands, professional newsletters are the most direct alternative to LinkedIn Ads. LinkedIn lets you target by job title and industry, but it's one of the platforms with the highest CPM on the market, and your ad competes in the feed with everything else.

A professional newsletter reaches that same profile (executives, marketing, tech, finance…) in their inbox, inside content they read for work and recommended by someone in their field. Since the CPM gap is much smaller than with Meta, the decision stops being about price and becomes about attention and credibility.

Our recommendation: use LinkedIn to target by job title at scale and professional newsletters to build credibility in a niche.

How long does it take to close a sponsorship?

It depends on each campaign, but you'll typically receive a proposal within 48 to 72 hours after telling us your goal.

Once the budget is approved, we coordinate publication within a few days, depending on the availability of selected newsletters.

What types of ads/sponsorships can be published in a newsletter?

Newsletters allow different sponsorship formats, depending on each creator's style. Some of the most common are:

Banners or logos
Mentions within the content
Reviews or recommendations
Sponsored links

In managed campaigns we prepare the copy and banner adapted to each newsletter's format. If you already have your own creative, we can use it too.

How do I get the invoice? Do I need a Niusleters account?

You don't need an account. With managed campaigns everything reaches you by email: the proposal, a single invoice for the total agreed budget, issued by us, and the final report.

You don't have to handle multiple invoices or contact each newsletter separately.

How do I pay for a managed campaign?

You can pay in two ways:

Bank transfer: no additional cost.
Card payment: through Stripe, with a 3% surcharge for using the gateway.

Payment is made after you accept the proposal, within 7 days. We take care of paying each newsletter.

Can I choose the newsletters or do you choose them?

We send you a proposal with the newsletters we believe best fit your sector, target audience and budget. You decide which ones publish your campaign: you can request changes, remove options or suggest specific newsletters you already know. Nothing publishes without your final approval.

Do you guarantee the results of the campaign?

We guarantee the number of impacts in the package you book, counted as real opens. An impact is one open of the edition your ad appears in. Seven days after each send we collect the opens from each newsletter's platform stats and include screenshots in the final report. If the total comes in below the package minimum, we run your ad in more matching newsletters, at no cost, until the impacts you booked are reached.

What we cannot guarantee are clicks, subscribers or sales. The success of a campaign depends on your offer, the message and the creative, how well it fits each newsletter's audience and the timing of the send. What we do is stack the odds in your favour, picking newsletters that match your brand, reviewing the content before it goes out and sending you a final report with opens, clicks and CTR per newsletter so the next campaign lands even better.

Do I have to commit for several months?

No. Ongoing management runs month to month and you stay as long as it delivers. If you want more reach, you can prepay three months and get 25% more impacts every month.
