What is CPM?

In email marketing, the cost of sending a thousand emails is referred to as CPM (cost per mile). Email service providers (ESPs) employ this price structure, also known as CPT (cost per thousand). The price covers the cost of the mail server, hosting pictures, bandwidth, bounce management, and deliverability services.

The cost per thousand emails is dependent on CPM. So, if a vendor's CPM rate is $30, sending 10,000 emails will set you back by $300.

To do the math:

(No. of Emails /1000) x CPM Rate

In digital marketing, on the other hand, an impression in CPM is the number of views/engagements an ad receives. Because impressions are such little units of measurement in marketing, they're counted by the 1,000. The lesser your CPM, the lower your ad cost, and the more revenue you generate.

Why should marketers use CPM?

You can use CPM to determine whether an email sponsorship/advertising opportunity is costly, inexpensive, or just right.

For marketers and advertisers, CPM is an important measure since:

• it provides an accurate picture of impressions

• you’ll recognize what's performing effectively with your audience;

• you’ll learn which of your content and campaigns are the most popular, and

• you'll have a better understanding of your brand's recognition.

However, CPM does not equal reach because impressions are not unique. After all, the same visitor could see your ad more than once. That’s why cost per click, click-through rate, and open rate are significant. You require them to assess the actual price of sponsorships.

How does CPM work?

Depending on the channels you're utilizing to attract new consumers or keep existing ones, you'll need to consider a variety of KPIs.

Facebook

Facebook takes the cost you spent on your campaign, divides it by the total number of impressions, and multiplies by 1,000. That’s your CPM. To find it,

1. Go to the Ads Manager.
2. Select "Performance and Clicks" from the Columns drop-down menu.

3. Scroll to the CPM column on the right.

4. Alternatively, you may use the drop-down option to select Customize Columns, check CPM and click "Apply."

Email campaigns/newsletters

The majority of email service providers use a tiered price structure. As the number of emails sent increases, the CPM rate usually decreases.

The CPM for a healthy newsletter is between $15 and $30. Your CPM can reach $100+ in rare cases when your newsletter has an audience that buys luxury products.

Some ESPs may use different price schemes. The CPM rate, for example, may be determined by the number of contacts in the client's database. Subscriptions and fixed fees are two more prominent pricing schemes.

Companies that send many emails can negotiate a lower CPM cost with their email service provider. Billing is normally done per campaign or monthly.

YouTube

CPM shows how much advertisers per 1,000 views pay content creators. But those are earnings before revenue share.

YouTube takes a 45% cut. Moreover, not all views are monetized. Because some views are repeat views. Others aren't counted until they watch for at least 30 seconds. The idea is to verify that genuine people are watching and consuming your material.

To check out your YouTube CPM, go to your YouTube Studio dashboard. Then, go to analytics and see how much money you've made from your estimated monetized playbacks. The average YouTube CPM is listed below:

4 common factors affecting CPM

The following factors may or may not be in your control when pre-determining CPM:

• Geographical location: A factor that may affect the price is the population's purchasing capacity.
• Device: Even though mobile has overtaken desktop traffic, desktop CPMs are higher due to greater conversion rates.
• Website: A high-quality website may request high rates for CPM.
• Time of the year: Holidays like Black Friday, for example, may motivate shoppers to spend more. CPMs will rise as a result of this.
