Email Marketing
Email list segmentation: send each person something relevant.
Sending every email to everyone is the quickest way to raise unsubscribes and complaints. Segmentation uses data you already have to match message and audience. We choose segments that are worth maintaining, build them in your platform and test whether they help.
When You Need This
The situations where this work pays for itself.
Signs it is time
- Every campaign goes to the whole list
- Unsubscribe or complaint rates rise on promotional sends
- You sell several product lines or serve different customer types
- You have store and email data that is not used for targeting
- You want to protect deliverability by mailing engaged people more often
What you get
- A documented segment list with exact rules
- Segments built and tested in your platform
- A content and cadence plan per segment
- A short results review with next segments to try
How We Do It
A clear process you can follow along with.
1. Audit the data you actually have
We list the fields and events in your platform: signup source, purchases, product views, clicks, location and any survey answers. Segments are only as good as the data behind them.
2. Start with a few durable segments
We usually begin with engagement (active and lapsed), customer status (never bought, first-time, repeat) and main product interest. A handful of well-kept segments beat dozens that nobody maintains.
3. Define each segment in precise rules
Each rule is written down, such as purchased in a time window or clicked a category, so anyone on your team can read and rebuild it. Dynamic segments update automatically.
4. Match content to each segment
We plan what each group should receive, such as replenishment reminders for repeat buyers or education for non-buyers, and avoid pushing offers on people who just purchased.
5. Protect your engaged audience
We map a sending cadence by engagement so recently active contacts get regular mail and less active ones get fewer, with a re-engagement path before suppression.
6. Test and measure properly
We compare segmented sends with a comparable unsegmented one, and look at clicks, revenue per recipient and unsubscribes rather than opens alone, since privacy features distort open data.
Mistakes We Help You Avoid
Common ways this goes wrong, and what we do instead.
Over-segmenting
Tiny segments are hard to test and expensive to maintain. We start small.
Relying on opens
Mail privacy features inflate open data. Clicks and revenue are more reliable.
Stale static lists
A list built once goes out of date. We prefer dynamic rules.
Collecting data you never use
Extra form fields cost conversions. We ask only for what changes the message.
Frequently Asked Questions
How many segments do I need?
Fewer than most people think. Start with engagement, customer status and main interest, then add more only when a segment earns its upkeep.
Does segmentation improve deliverability?
It often helps because relevant mail gets fewer complaints and more engagement, which are positive signals. It is not a guarantee.
Which platforms can do this?
Klaviyo, Mailchimp and most modern platforms support rule-based segments. The depth of behavioral data depends on your store integration.
