More-effective marketing
Whether you have an old customer list you’ve accumulated over the years or you’ve purchased a list, list segmentation can give you valuable insight into customer behavior and preferences that should not be overlooked. The question is: how can you, as the business owner, accomplish this without breaking the bank? It’s easier than you think.
Glossary
List segmentation – the process of dividing your customer list or database into logical buying groups.
Targeted messaging – crafting messages that specifically resonate with a person or group. For example, using imagery and copy tailored to men versus women, or luxury versus budget shoppers.
Targeted landing page – a web page with content explicitly aligned to the visitor’s journey or segment.
Analytics – tracking, monitoring, and tallying customer responses to a campaign so you can measure results and refine your approach.
Identifying lists
By way of example, let’s look at the fictional car dealership, Rocket Auto.
Rocket Auto has a customer list of previous buyers. They’re fortunate because in the buying process most customers completed a credit application packed with marketing-useful data: age, gender, marital status, income, and more.
They also maintain a second list: every shopper is asked to complete a buyer-profile card. For customers who don’t buy, this card is used as a follow-up tool. The profile asks similar demographic questions and also asks about their vehicle interest: primary car, second car, luxury car, one for the kid, etc. This helps salespeople stay alert for the right fit if the shopper leaves without buying.
Segmenting a list
What Rocket Auto lacks is the understanding of how to use this data — so let’s walk through one possibility.
The first part of segmentation is already done: buyers vs. shoppers (those who did not buy).
For their first targeted effort, they’ll offer a $2,500 buying credit and create two versions of the message:
- “Thank you for your business.” (going to buyers)
- “Come see our new inventory.” (going to shoppers)
The second segmentation divides each list further by gender, age, and income:
Group A: Men earning <$50K → ages 21-40 / 41-55 / 55+
Group B: Women earning <$50K → ages 21-40 / 41-55 / 55+
Group C: Men earning >$50K → ages 21-40 / 41-55 / 55+
Group D: Women earning >$50K → ages 21-40 / 41-55 / 55+
Group E: Men earning >$100K → ages 21-40 / 41-55 / 55+
Group F: Women earning >$100K → ages 21-40 / 41-55 / 55+
That gives 24 discrete versions: six income/gender/age buckets for each of the two lists. While it seems like extra work up front, Rocket Auto knows that tailored messaging will boost response rates. Even if the improved response yields just two new customers because the message landed with the right person, the time spent is justified.
Messaging and call to action
To appeal to these varied buying groups, Rocket Auto will change the graphics and headline for each of the 24 emails — but the core message remains the same.
Graphics play a major role in any email, so Rocket Auto is selecting imagery and headlines that speak to each segment.
Note: There are many inexpensive stock-image libraries such as YAY images, Adobe Stock, etc. as well as AI generators that can create usable images — making tailored campaigns affordable.
While HTML emails (image + text) are popular, you can still send plain-text and get decent results — but you may sacrifice a bit of response rate for cost savings.
Each email includes a clear CTA: “Click here to print your voucher for $2,500 off your next purchase.”
Select an email service
Rocket Auto uses a modern marketing-automation system, which makes it easy to upload and segment lists using clear naming conventions. They upload the 24 email versions and connect each to the right segment.
With dashboards, they track who opened, clicked links, unsubscribed, etc.
There are many systems such as Mailchimp, ActiveCampaign, and HubSpot that make easy segmentation and analytics. If you have a very small list you might use simpler tools — but the point is: your system must support segmentation, automation, and measurement.
Targeted landing pages
Some marketers skip dedicated landing pages and send all traffic to the home page. Big mistake. If you send 24 different emails to 25,000 people (for example) and direct them to your homepage, you lose tracking clarity and weaken the message match.
A targeted landing page ensures the user feels they’ve come to the right place, and you can track which segment they came from.
Rocket Auto ensures each landing page:
- uses the same imagery and tone as the email
- includes the offer details, possibly registration forms and deep-links
- tracks engagement using a modern analytics platform (e.g., Google Analytics or equivalent)
They monitor metrics including: visitor count, time on page, bounce rate, session depth, new vs returning visitors, and referral source.
Putting it all together
In this campaign: two primary lists × six segment buckets = 12 segments each = 24 emails and 24 landing pages. With segmentation, tailored emails and landing pages, Rocket Auto sends and watches the dashboard.
When they check their dashboard they see:
- how many email sends
- how many bounces and why
- how many unsubscribes
- how many opens/clicks per link
- which segments are performing best
Their analytics reveal, for example: men aged 41-55 earning >$100K produced a 45% click-through in both campaigns — a major hit.
With that data they now have a clean subset of contacts they can market to: men in that age/income group who received emails (whether or not they clicked) and did not opt out. They queue up a sports-car campaign targeted just at them.
What the campaign taught Rocket Auto: targeting buyers under 40 earning less than $50K produced nearly no results. That’s logical — buyers with limited income aren’t ready for a second vehicle even with a $2,500 voucher. Perhaps wait a year or two before sending offers to that group.
Segmenting your list—paired with tailored messaging and analytics—will make you a better marketer. Sometimes a segment doesn’t respond, and that’s fine, the insight is still valuable. No scientific study is needed to tell us: messages that matter to people work better than blasts meant for the masses.
