What Is Mailing List Segmentation?
Mailing list segmentation refers to the breaking down of your direct mail audience into smaller groups based on criteria that matter to you, whether that’s demographics, location, buying behaviour, or customer value.
Instead of blasting out a one-size-fits-all campaign, you send different versions of your mail to different audience segments. This could mean changing the imagery, wording, offer, or even the product focus to better match each segment’s needs.
For example, lapsed customers will receive a different message from those who have yet to make their first purchase, and a mailer promoting a new women’s anti-ageing day cream will only be sent to women 40+.
Why Segment Your Mailing List?
It’s simple: not all customers are the same, and they shouldn’t be treated as such. Here’s why mailing list segmentation improves direct mail performance:
Increased Relevance
Messages tailored to a recipient’s needs, location, or interests are far more likely to be read.
Better Engagement
Segmented mail feels more personal and less like “junk”.
Higher Conversion Rates
You’ll speak to the right people at the right time with the right offer. Personalised direct mail has shown to increase conversion rates up to 50% versus non-personalised mailers.
Smarter spend
Avoid sending expensive print and postage to low-interest or ineligible recipients.
The result? Your marketing budget goes further, and your brand stands out in the letterbox.
Key Ways to Segment a Mailing List
Let’s look at some of the most effective segmentation strategies you can apply to your mailing lists:
Demographic Segmentation
Segmenting by demographic details such as:
- Age
- Gender
- Household income
- Marital status
- Occupation
Example: A healthcare provider might send different messages to younger adults vs. retirees, or a retailer may tailor offers based on income levels.
2. Geographic Segmentation
Target recipients based on:
- Postcode
- Region or city
- Urban vs. rural areas
Example: A supermarket chain segments its mailers by postcode to highlight offers available at each local store, and promote in-store events or opening times that vary by location.
3. Behavioural Segmentation
Use past behaviours and interactions to guide your strategy:
- Previous purchases
- Response history
- Website visits or online activity
- Loyalty or engagement level
Example: A retailer could send exclusive discounts to customers who haven’t purchased in the last 6 months to reactivate interest.
4. Transactional Segmentation
This includes data like:
- Average order value
- Frequency of purchases
- Recency of last transaction
Example: Segment your best customers and send them VIP offers or priority access to sales.
5. Customer Lifecycle Segmentation
Group recipients based on where they are in the buyer journey:
- New leads
- First-time buyers
- Long-term customers
- Lapsed customers
Each stage may require different messaging, offers, or calls to action.
How to Gather Segmentation Data
You don’t need to have every data point under the sun to start segmenting. Here’s how to build up useful segmentation information:
Use What You Already Have
Look at your CRM or past order history. Often the most valuable insights are already sitting in your systems.
Capture New Data with Campaigns
DMS can help you design surveys, questionnaires, or response cards to gather additional data from your audience – perfect for enriching your database.
Work with a Data Provider
For large or commercial lists, DMS can enhance your existing records with demographic and lifestyle data from GDPR-compliant providers.
Clean and Update Regularly
Old or inaccurate data leads to poor targeting. Our data processing services ensure your segmentation is always based on accurate, up-to-date information.
Practical Tips to Segment Your Mailing Lists
Here are some easy ways to apply segmentation effectively:
Start Small
You don’t need ten complex segments right away. Begin with one or two simple filters, like new vs. returning customers or by region – and build from there.
Tailor the Message
It’s not just about who you’re mailing, but what you say to them. Make sure the content of your mailer matches the interests and needs of each segment.
Test & Refine
Try A/B testing with different audience segments. See which ones respond better to certain offers, designs, or formats.
Track the Results
Measure response rates by segment to understand what’s working. Over time, your campaigns will become more efficient and effective.
