Hunting - new, relevant and accurate data - every week. That's what you'll receive as we believe recency = relevancy. As part of that you'll unlock newsletters of all sizes and niches; micro-influencers to larger publications.

Decision making data

Most services like ours are normally 'one-way'. They focus only on providing value to one party: the newsletter or the sponsors.  We work with both sides to better match opportunities.

Because we work with "the other side" we ask them for data such as open rates, click through rates and ad cost rates. This means richer data so you can make a quicker and well informed placement decisions. (This data isn't always available, but when it is, you have access to it).

Most common objections

Everyone is using this list

You'd think so, but the opposite is true:

  • If a competitor is actively advertising, this gives you in insight into what your competition is doing
  • Different sponsors target different niches
  • Relative to the millions of brands and sponsors in the world, we work with a tiny few
  • We will raise the price every 100-150 subscribers to maintain integrity of the information
My marketing budget is too small

Different newsletters are of different size and circumstance:

  • Some are part time writers and can be considered micro-influencers.
  • Some are full time but rely on sponsorship revenue for an income.
  • Others are larger and have a network of sponsors they regularly work with.

Ultimately newsletters are looking for brands their audiences align with. Your sponsorship is a way for them to do that. Because they're looking for sponsors and revenue.

It's like how brands pay micro-influencers for a social media post. So your budget will never be too small to start micro-advertising.

I'm not technical and have no time for new tech

You don't need to be technically minded to use our data. Whilst most services like ours lead with technology platforms that require a learning curve and 'lock-in', we focus on making the data available to you quickly and easily. The data is in a simple table (like Excel) that can be filtered based on what you're looking for.

Plus we don't lock you into our platform. For example, we simply provide the raw email, LinkedIn contact, and social accounts so you can directly contact the newsletter. We don't force you to message through our platform.

Our Guarantee

This month we'll spend 100+ hours curating data for our Email Sponsorship' customers. We'll then email them that data weekly for speed. Therefore we don't offer any money back guarantees, because the data has now been seen. It's like buying a book, reading it cover to cover and then asking for a refund. However if you feel our research does not help you get sponsored, build relationships or cross-promote, then you can cancel at anytime, hassle free. Plus you'll get the remaining data for the month your subscription is active.


What is the source of your information?

All data points in our lists, including contact emails are publicly available.

Our sources include email subscriptions, news outlets, social media, niche blogs are more.

We collect data by hand and even contact newsletter operators and sponsors to cross-reference the data.

It's process. But what it means for you:

  • The data isn't perfect, but its hard won (it's manual, collaborative and iterative).
  • The data is publicly available and not the result of illegal activity (just lot's of manual work).

We are always open to our subscribers validating data. Feel free to email us and say "Hey, that newsletter now has 15,000 subs. Not 12,000" or "That newsletter actually had a 3% CTR, not 1%".

Am I going to be competing with other brands, advertisers, sponsors, startups and agencies?

Yes and no. Yes because there are other sponsors taking advantage of our research and data.

No because:

  • If they're sponsoring a newsletter, so could you
  • Different sponsors target different niches
  • Relative to the number of brands and sponsors in the world, we work with a tiny number of customers
  • We don't just work with sponsors, we work with newsletters to find out what they want, so we can do warm introductions

We offer sponsors the chance to stand out by providing more useful information to share with newsletter operators.

Finally, to ever avoid a situation where we have too many sponsors competing for newsletter placements, we raise the prices every 100-150 subscribers to filter out low quality advertisers. The price you pay today is the price you lock in.

Why should I subscribe to Email Sponsors?

There's a lot of newsletters out there and with the introduction of Substack, Beehive and Linked In Newsletters, the industry is growing.

So how do you get in the front of line to the best, with the best audiences?

Not just any newsletter. An active newsletter creator who is building a highly-valuable, loyal audience.

You could spend 10+ hours every week on researching, shortlist and keeping on top of your own list.

And repeat that activity every week to ensure you have the latest data and keep on top of your campaigns.

Or you could leave that to us, your personal research team. Where it's our job to: find quality data, keep updating data, ensure accurate information and target great newsletters

Do you guarantee I'll get a placement and high advertising performance?

Unfortunately not.

Our service focuses on getting you and newsletter operators the best information possible for a warmer introduction. We aim to increase the chance of you placing a campaign with an active newsletter. Compared to a cold, unqualified outreach.

To further increase your chances we do newsletter outreach. To better understand what they need from sponsors. With the aim of helping you best prepare for when you land your first or next email newsletter placement.

What if I want to cancel?

Drop us an email and we'll get your subscription cancelled, hassle free. No clever tricks to get you to stay.

We're always open to feedback to know what we could do better to help you as an advertiser.
