Email Segmentation That Makes Every Send More Relevant.
Sending the same email to your entire list produces mediocre results across the board. The brands with the highest email revenue per subscriber use behavioural, demographic and purchase-based segmentation to send highly relevant content to the right subset of their list at the right time.
Why Segmentation Is the Highest-Leverage Email Optimisation Available.
Segmentation divides your email list into smaller groups and sends more relevant content to each rather than the same message to everyone. The more relevant each email is to the recipient, the higher the open rate, click rate and conversion rate. Conversely, the less relevant, the higher the unsubscribe rate and spam complaint rate. Every email metric improves when relevance improves, and relevance improves through better segmentation.
Behavioural segmentation: the most powerful segment type
Behavioural segments are built from what contacts actually do rather than who they say they are. A contact who has opened every email in the last 30 days is a different segment from one who has not opened in 90 days. A contact who purchased 3 times is a different segment from a one-time buyer. Behavioural data is the most accurate predictor of future behaviour and therefore the most valuable input for segmentation strategy.
The engagement suppression segment
Building a suppression segment of chronically unengaged contacts and excluding them from your main campaign sends is the single fastest way to improve your open rate, click rate and deliverability simultaneously. Contacts who have not opened in 90 days are dragging every aggregate metric downward while also harming your sender reputation with inbox providers. Removing them from main sends and routing them into a re-engagement sequence immediately improves the health of your overall programme.
Key Services and Approaches We Use.
Engagement-Based Segmentation
We build engagement segments dividing your list by open and click frequency over the last 30, 60 and 90 days, enabling targeted sends to your most engaged contacts and re-engagement sequences for lapsed contacts.
Purchase History Segmentation
We segment by number of purchases, time since last purchase, product category and AOV to enable targeted cross-sell, upsell and loyalty campaigns matching each contact purchase history.
Demographic and Preference Segmentation
We build segments using any demographic data collected at signup or through preference centres, enabling content personalisation by interest area, role or industry.
Predictive LTV Segmentation
We use platform predictive analytics to segment contacts by predicted lifetime value, enabling you to prioritise your highest-value customers for exclusive offers and early access.
Suppression Segment Management
We build and maintain suppression segments excluding bounced contacts, recent purchasers from acquisition campaigns and contacts who opted out of specific send types.
Segment Performance Reporting
We track open rate, click rate and revenue contribution by segment monthly to identify which segments are performing, which are declining and where new segmentation opportunities exist.
Tactics That Improve Results Faster.
Start With Engagement Segmentation First
Engagement-based segmentation by open and click recency is the single most impactful segmentation for most programmes. Building this one layer and sending campaigns to your engaged cohort typically improves open rate by 20 to 40 percent immediately.
Build Suppression Lists as Carefully as Targeting Lists
Your suppression segments are as important as your targeting segments. Excluding recent purchasers from acquisition campaigns and non-consented contacts from all sends prevents wasted sends.
Refresh Segments Before Every Major Send
Dynamic segments update automatically in most email platforms. Verify before every major campaign that your segments are pulling the correct contacts.
Use Purchase Frequency as a Segmentation Axis
One-time buyers, two-time buyers and three-plus time buyers are fundamentally different segments. Each warrants a different communication strategy with different offers and content.
Create a Winnable Re-Engagement Segment
Segment lapsed contacts by time since last purchase and time since last open rather than treating all lapsed contacts as a single re-engagement audience.
Test Different Messages to Each Segment in Parallel
When you segment your list, test whether the same offer framed differently for each segment outperforms a single generic message. The additional effort of 2 to 3 variants is consistently justified.
Cap Campaign Sends for Recently Emailed Contacts
Contacts who received an automated flow email in the last 3 days should often be excluded from campaign sends to prevent overfrequency.
Document Your Segment Logic
Write down the exact definition of every segment in your email platform including criteria, platform filter settings, last reviewed date and what it is used for. Undocumented segments become unmaintained segments.
