Ad Network Case Study: Get More Newsletter Subscribers

It’s time to talk to people not ‘subscribers’.

The passion economy is bubbling up and boiling over. With media distrust at an all time high, people are trusting influencers to curate information into newsletters. Social engagement is fragmented over thousands of micro-communities. 

And email advertising is finally opening up to advertisers.

A while back, we gave three publishers (newsletter owners) $100 each to see how much it cost to get new subscribers on Facebook. The results were mediocre. 

This time, we tested the power of newsletters. 

Setting up on the email-based Ad Network 

The conversion goal was to get more subscribers for each publisher at the lowest cost possible. 

Paved’s Ad Network is a form of advertising similar to social media. You can target people based on their demographics, interests, job titles, and professional attributes. Except instead of a feed, it appears in someone’s favorite email newsletter. 

We partnered with 3 publishers in the tech space to advertise their newsletters on the Ad Network: 

It’s pretty simple to set up ads and get them live. Here are the parameters we used for each publisher.

Targeting & Budget

To keep it simple, the location for all campaigns was set to North America. The rest of the targeting criteria was done via contextual targeting — aka content/topics that someone has engaged with over the last 30 days.

*You can target by sites visited or clicked

Daily Budget: $20
The higher your daily budget, the faster you get results

Bid Type: CPC
The goal was to get signups, so cost per click was most effective. For brand awareness campaigns, choose CPM (cost per thousand impressions).

Bid Amount: $0.50
A newsletter subscriber offers a very low lifetime value to a mid-sized publisher (around $7 spread out over 2 years), so we lowered the bid significantly. This means it took much longer to get results as plenty of other advertisers out-bid us for the audience. For higher value sales and niche audiences (like CEOs and managers), you want to increase the bid to minimum $3.

Frequency Cap: 1 impression per subscriber
Newsletters need subscribers to open emails for the next 6 months to a year to be profitable. If a subscriber isn’t interested in the ad the first time around, they weren’t passionate enough for our publishers. This is different for high-value sales, SaaS software, and DTC products. In most cases, we recommend 7-14 impressions every two weeks.

Reporting

Paved automatically reports impressions and clicks (note: tons of bots can show up as ‘fake’ clicks. We filter those out. You can read more about it here. You will also want to track signups/acquisitions (also know as conversions or your CPA). Use a UTM link or a pixel.

If you don’t track your ad performance, you gamble away your budget.
It’s like giving a lump sum to a financial advisor, never looking at it again, and saying “I’m sure I’ll be able to retire in 30 years”. Maybe… or maybe that advisor lost it all on a risky Bitcoin bet. Best to check. 

A/B Testing The Copy and Creative

Have you heard of an A/B test? It’s when you take two versions of something and test them against each other to learn which version resonates best with a certain audience. 

When testing, it’s a good idea to start with wildly different ads and narrow down from there. Pick the winner and see if tweaking the headline boosts clicks or conversions. 

For example, if you are selling meeting management software to managers and know that the concept of time-wasting resonates, you could test which message gets more traction: 

Stop Wasting Time in Meetings vs. Make Your Meetings More Efficient. 

A/B test things like:

  • Main Message/Value Proposition
  • Pain point vs Solution
  • Long Term Benefit vs Short Term Benefit
  • Long Term Pain vs Short Term Pain
  • Headlines
  • Button text
  • Images of people vs Graphic Elements
  • Body Description

The highlighted ad got the highest CTR (click-through rate) and the most clicks. The click-through rate is important because it shows the ratio of which ad was more effective no matter how much money was spent.

How to use these results to create and improve your own ads

This is a tiny experiment. But from it we can start to make some hypotheses and notice a few trends. 

  1. Photos/realistic images do better than plain graphics
    Every single graphic version lost. Every single ‘bright’ image also lost. This means darker, higher contrast photos did better. Possibly because the Ad Network images appear quite small on a desktop email. The darker and higher contrast it is, the better it catches your attention. 
  1. Emotional headlines perform better than fact-based ones
    FOMO, useful tools, hackers starting afternoons. These are all grounded in a bit of emotion. It’s been proven many times over that us humans buy things with emotion more than logic, so this hypothesis is probably correct. 
  1. Headlines speaking to YOU performed better than those appealing to a general audience
    What’s the difference between “Front End Web Developers” and “Web Devs”? Well, if your job title says “front end web developer”, you might refer to yourself casually as a web dev. It’s the group you identify with. You end up thinking “ah yes, I’m this type of person, this will be related to me”.
  1. The button text and descriptions need more testing
    We didn’t see a clear difference there, so it’s no use guessing. When testing, you should always note what needs more experimentation so you can keep improving. 

What is the ad score? 

The higher the ratio of people who see and click an ad, the higher an ad score. Ad score is a quick way for you to tell if your ad is performing well or not. And the higher it goes, the more the ad will be prioritized in the network.  

Using the Ad Network to create targeted email ads

Email advertising is powerful. And it can be a valid alternative to expensive targeted ads on social media. The takeaway from this experiment is to continue experimenting

Unlike well-documented platforms, this is a relatively untapped market. It’s new and fresh. People who subscribe to newsletters actually read. They’re paying attention. It’s up to you to capture and convert that attention into subscribers and sales.
