Over 4 billion people – more than half the global population – use email to get customized messaging delivered directly to their inboxes, where they spend hours each day. And that’s great news for publishers. In the inbox, there’s no competition with ever-scrolling social feeds or search results. Once someone clicks your email, it’s just you, your reader, and your content.
Still, you need to know how to offer up that prime advertising real estate to brand partners and optimize your yield to increase your revenue. So, you have to nail the specifics – like newsletter formatting, Gmail clipping, price floors, and ad sizes.
With these best practices for yield optimization, your email monetization strategy will be a success.
The right newsletter template can make or break your email monetization strategy.
While two-column formats (like side-by-side blocks of content) are common, they’re also visually complex and can make it tough to fit ads seamlessly into your newsletters.
It’s better to opt for a single-column layout, so you can easily map out where you want your ads to go and make sure sponsored content is properly balanced with organic content.
Incorporate multiple ad sizes
Speaking of single-column templates, they’re also ideal for supporting multiple ad sizes. And the more ad sizes you offer to advertisers, the more likely you are to increase bid density and optimize yield.
For example, you might offer standard IAB sizes, high-impact sizes like 970×550, and custom sizes according to your content formats and advertiser demand.
Offer collapsible ad slots
If demand is low during a particular time and there are no ads to fill one of your slots, you don’t want a big empty space left in the middle of your email. Or, perhaps even worse, you don’t want to have to recode your whole newsletter at the last minute.
Enter: collapsible ad slots. They’re programmed to automatically collapse in a single-column email format if there’s no ad to display. You can rest easy knowing it won’t throw off your email layout or interrupt the reader experience.
Account for Gmail clipping
Gmail is responsible for 30% of all email market share, so if you launch email newsletters, a good portion of your readers will likely view them on this platform. Be sure, then, that your emails are easily digestible on Google’s email service.
The most important thing to know is that Gmail limits newsletters to 102KB and clips emails bigger than that. So, ads running at the bottom of your newsletter that are past max capacity won’t be visible, and you’ll lose revenue.
Long story short: Keep those emails under 102KB. If any run longer, segment them into smaller emails and release them separately.
Set up block and allow lists
If brand safety is top of mind for you these days, you’re not alone. The pandemic and recent political discourses have left publications particularly wary about where and when they run ads.
The good news is that you can have control over this. Just set up block and allow lists to filter ad content served in your emails. These lists of approved and denied domains and categories can help keep your content safe and relevant for your audiences.
Find your price floor
Your price floor is the minimum CPM you’ll accept for a bid to fill an ad slot. It’s important to know when to adjust or even remove your price floor to increase competition and revenue.
For example, if your newsletter slots fill 90% of the time, you know your price floor is working. Even so, you could try increasing your floor by $0.10. If demand remains about the same, you’re still filling your slots while making more money. If demand tapers off, maybe it’s best to drop that price back down.
If your newsletter isn’t filling as well you’d like it to, on the other hand, you might want to reduce or remove that price floor to drive more bids.
Make the most of the above-the-fold real estate
Ads placed at the top of newsletters historically drive more clicks and revenue for publishers. Since they’re the first ones people see, they’re more valuable to bid on.
It’s simple. Make sure that above-the-fold real estate is full of high-quality content, including ads, so it catches the eye and generates impressions – before readers even scroll down or start clicking.
Clean your subscriber lists
If you run an email newsletter, you’re sitting on a wealth of valuable first-party data that you can use to optimize targeting, grow your audience, and learn about your readers.
Keep that data clean and accurate by regularly flushing your subscriber lists of bots, dummy-email accounts, and inactive users. This way, you know you’re offering only the highest-quality audiences to advertisers. And that’s the best way to set yourself up for success with email monetization.
