So what is this mistake we are all making?

The mistake: We send one email to our entire database

That’s right. 89% of marketers do not segment their database and send one email to all in the hope that at least a few readers will take action, just like the old ‘spray and pray’ approach. Why else do you think people refer to email marketing as sending an ‘email blast’?

10 ways to segment your email database

Targeting and personalization are now a top priority for digital marketers, along with Conversion Rate Optimization and Content Marketing. In fact, it's one of the fastest growing priorities as marketers can now see the impact of targeted campaigns compared to the one size fits all approach.

To help get you started, here's 10 ways to segment your email marketing subscriber list.

Let's dive right in!

1. Location

Have you ever sent an email to someone who lives in a country you do not ship to? Or how about inviting subscribers to attend a 1 hour seminar in London when they live in Spain?

Knowing where your subscribers are located is powerful data that can be used to fine tune your targeting efforts. Instead of sending an email to all, send emails to those who live in the surrounding area of your event or conference, and increase the number of seats filled.

2. Industry

If you're business to business, you will be selling to organizations across many different industries. Knowing the industry your leads work in can add a great level of personalization. For example, using case studies and content around the industry you email to can help increase response rates.

3. Job title

Your email list will include chief executives, consultants, customer service agents and human resource managers. It's a diverse list. Should you send the same content to a marketing director and HR manager? Probably not

Segmenting your list my email type will help deliver a more relevant message to your audience.

4. Website behavior

Do your customers visit your website on a weekly basis? How often do they log in to their account?

If you can notice behavioral trends on returning visitors, specific pages they visit you can send targeted emails based on this behavior. Amazon is a prime example of how effective email marketing can be when targeted.

5. Company size

Often an approach used in account-based marketing strategies, separating content by company size or revenue can help increase response rates. A small business with less than 20 employees and revenues of $500,000 will have different needs compared to a Fortune 500 company that has more than 10,000 employees and generates $20+ million per year.

6. Interests

What are your interests? If you are passionate about email marketing, are you more likely to read content about that includes B2B email marketing examples or content about CRM database input administration?

Filter email subscribers by interest or product category to make the message more relevant to the reader, and you can even use past purchase history to identify the interests for those who have already signed up to receive emails.

7. Sales cycle

For buyers' who have just started out researching the industry and are collecting comparison data; these subscribers should be sent research related content - white papers, industry reports, etc. whereas someone who is later in the buying cycle, closer to making a decision should be receiving information on software free trials, product demos and webinars.

8. Age

Would you send the latest cat meme to a 55 year old based in the country side? Likewise, would you send your nineteen year old drinking buddy a 50 page industry research report? Maybe you would, but by segmenting by age, you are able to identify who your target audience is.

9. Language

If you’re an English speaker and work in Japan, do you receive English emails with offers that are only for valid to the UK or do you receive emails in a language that you do not understand?

International email marketing is a challenge. However, you can start by segmenting by language and cross-reference this data with location to identify the content the subscriber wants to receive in order to provide the best value.

10. Customer value

Customers who spend more with your brand are more loyal to you than those who don't. Use the data on these customers to keep them engaged by sending them personalized emails and exclusive promotions.

Use a similar approach for subscribers who signed up but haven't bought. Entice them with offers to get them to make their first purchase.


If you’re not seeing a high return on your email marketing campaigns, you are making this email marketing mistake. You need to change your approach today!

Use these segmentation tips to start sending relevant content to your readers and become better at email marketing, which will help you your business grow and will keep your customers happy.

Sending the right message to the right person and the right time will deliver a high ROI.
