Email Target Marketing: How to Send Emails People Open
Targeted email marketing means sending different messages to different groups of subscribers, based on who they are, what they’ve done and where they are in the buying journey, instead of sending one message to everyone. You build segments from data you already have, write for each segment, trigger emails off real behavior, and test what works. This guide walks through each step, the numbers behind it, and the US rules you need to follow.
TL;DR
- Targeted email marketing sends relevant messages to defined segments or individuals. It replaces the single message sent to the whole list.
- Start with three to five segments built on behavior (purchases, clicks, cart activity) and lifecycle stage. Add demographics or firmographics later.
- Automated, behavior-triggered flows such as abandoned cart and post-purchase usually outperform one-off campaigns. Keep a few well-built flows running before you add more sends.
- In the US, CAN-SPAM covers every commercial email, including B2B, and requires accurate headers, honest subject lines, a physical address and a working opt-out.
- Test one variable at a time, and make sure the page the email links to matches the promise in the email.

What targeted email marketing actually is
The phrase “email target marketing” is usually shorthand for one idea: choosing who receives a message, and what it says, on purpose. A targeted email goes to a specific person or group, with a specific objective: a first purchase, a renewal, a reactivation, a demo booking.
The opposite is the blast: the same newsletter or promotion sent to every address on the list. Blasts are easy to produce and expensive in the long run. They train subscribers to ignore you, they push unsubscribe and spam-complaint rates up, and they give you almost nothing to learn from.
Targeting works at three levels, and most teams climb them in order:
- Segmentation. You split the list into groups that share a trait, and each group gets its own message.
- Triggers. An email fires automatically when someone does something: browses a product, abandons a cart, finishes onboarding, goes quiet.
- Individual personalization. Content, offers and product picks change per recipient, using the data points you hold on them.
You don’t need level three to see results. Level one, done well, already separates good programs from average ones.
Why it’s worth the effort
The numbers vary by industry and by how well segments are built, so treat them as direction, not promise. One roundup of 2025 industry data reports that segmented campaigns see up to 30% higher open rates and 50% higher click-through rates than broad sends. The same source cites revenue lifts of up to 760% for segmented campaigns. That upper figure is a best case, not a benchmark to plan around. Your own baseline matters far more than any published average.
The practical reasons are easier to see than the percentages:
- Relevance protects deliverability. When people open and click, mailbox providers read that as a good sign. When they delete unread, it works against you.
- You stop discounting to everyone. A returning customer who would have bought at full price doesn’t need the same coupon as a first-time browser.
- You learn faster. Small, defined audiences give you cleaner test results than a mixed list does.
Build your segments: where to start
The best segment is the one you can act on this month. Start with data you already collect and group people by what they do before you group them by what they are.
Behavioral segments
Behavior is the strongest signal because it reflects current intent. Useful starting groups:
- Browsed a product or category but didn’t add to cart
- Added to cart, didn’t buy
- Bought once, never twice
- Repeat buyers and high-value customers
- Clicked a specific topic in a past email
- Hasn’t opened in 90 days (adjust to your sales cycle)
Lifecycle and engagement segments
One B2B email guide lists buyer journey stage and engagement level among the core ways to divide a list: awareness, consideration, decision and customer on one axis, and active, dormant, at-risk and churned on the other. These two axes pair well. A dormant customer and a dormant lead need very different emails.
Demographic and firmographic segments
For consumer brands this means location, age range or stated preferences. For B2B it means company size, industry, revenue band and job function. The same guide lists these firmographics alongside journey stage. They matter most when your offer genuinely differs by group: a finance lead and a marketing lead rarely care about the same benefit.
A simple starting set
| Segment | Trigger or rule | Goal | Example angle |
|---|---|---|---|
| New subscribers | Joined in the last 14 days | First purchase or first action | Welcome, best sellers, how it works |
| Cart abandoners | Cart created, no order in 24 hours | Recover the sale | Reminder, objection handling, reviews |
| First-time buyers | One order | Second order | Usage tips, complementary products |
| Loyal customers | 3+ orders | Retention, referrals | Early access, loyalty perks |
| Lapsed | No open or purchase in 90 days | Win back or clean up | Check-in, preference center, last call |
Five segments are plenty. Many teams stall because they design twenty segments and never write the copy for them.
Triggered flows beat one-off sends
Campaigns are one-off sends to a list. Flows fire automatically when a recipient does something. A 2025 benchmark report from an email platform vendor says automated flows can generate up to 30 times the revenue per recipient of standard campaign sends, because they land at the moment of intent. Take that as a vendor’s data on its own customer base. The direction is consistent with what most practitioners see, though: timing and behavior beat the calendar.
A lean set of flows to build first:
- Welcome series (three to four emails over about two weeks)
- Abandoned cart or abandoned browse
- Post-purchase (thank you, how to use it, review request, cross-sell)
- Win-back for lapsed customers
- Lead nurture for B2B contacts who downloaded something but haven’t talked to sales
Campaigns still have a job: product launches, seasonal offers, news. Send them to the segments they fit, not to everyone.
Write for the segment, not for the list
Once the segment is set, the message has to prove you knew who you were writing to. A few habits do most of the work:
- Open with the reason you’re writing. “You looked at the trail running shoes last week” beats “Our latest deals.”
- One email, one action. A single clear button outperforms three competing links in most programs, and it’s far easier to measure.
- Match subject line to content. It’s good practice, and it’s also the law (more on that below).
- Use data the reader would expect you to have. Past purchases and onsite clicks feel natural. Details they never gave you feel invasive.
The 60/40 balance
A common guideline, the 60/40 rule, says about 60% of your emails should give value and about 40% should ask for something. In a five-email sequence, that is three value emails and two with a direct ask. It’s a rule of thumb, not a regulation, and the same source warns that a thinly veiled pitch dressed up as value is easy for prospects to spot.
Personalization with limits
First names in subject lines are table stakes. The bigger gains come from meeting someone at their stage: a different email for someone who has never bought and someone who bought last week. Email benchmark commentary argues that the real advantage lies in using the many data points available to match each customer’s stage in the journey, which automated flows do far better than one-time sends.
Watch two limits. First, don’t personalize beyond your data quality: a wrong product recommendation is worse than a generic one. Second, make sure every personalization has a fallback value for when the data is missing.
Test, then test the page too
Targeting is a hypothesis. Testing tells you whether you were right. Keep the discipline simple:
- Change one variable per test: subject line, offer, hero image, call to action or send time.
- Split the segment randomly and send at the same time.
- Decide in advance which metric decides the winner. Clicks or conversions are usually better than opens, which are less reliable now that mailbox privacy features load images automatically.
- Wait for enough volume before declaring a winner. A 2% difference on 300 recipients is noise.
- Record the result and apply it to the next segment.
Here is the step many programs skip: the landing page. An email that promises “20% off running shoes” and drops the reader on a generic homepage loses people after the click, and no subject-line test will fix that. Make the headline, offer and imagery on the page continue the email’s promise. If you have different segments, they deserve different landing experiences, even if the difference is only the headline and the first product shown.
Our perspective: close the loop between the inbox and the page
We build Loop Optimizations around one belief: ads, emails and landing pages are one conversation, and most teams optimize them as three separate jobs. A team tunes its email in one tool, its ads in another and its site in a third, and nobody checks whether the promise survives the click.
That’s why our platform treats email as one channel in a closed loop. It generates and tests marketing emails with Klaviyo, runs A/B tests on copy and visuals, rewrites and personalizes pages to match the promise that brought the visitor in, and attributes full customer journeys so you can see which message led to which result. Winners are reported with statistical significance, and the learnings feed back into the next round, across ad channels such as Google, Meta, TikTok and LinkedIn as well.
Our advice to any team starting with targeted email: don’t chase more segments. Chase fewer, better-tested ones, and make sure the page behind each email says the same thing the email did. The average results we report from our own customers are a 3.2x improvement in click-through rates and a 41% reduction in customer acquisition costs. Those are our averages, and individual results depend on your starting point, traffic and offer.

Stay on the right side of the rules
This part is where a mistake costs real money, so know the framework for your market.
United States: CAN-SPAM
The FTC’s CAN-SPAM compliance guide says the law covers all commercial messages, not just bulk email, and makes no exception for B2B. In summary, the FTC’s requirements include:
- Header information (From, To, Reply-To) must be accurate
- Subject lines must not be deceptive
- The message must be identified as an ad
- You must include a valid physical postal address
- You must give a clear way to opt out and honor opt-outs
Read the full guide before launching, and ask your attorney about edge cases such as affiliates or purchased lists.
If you email people in the UK or EU
US rules are not universal. In the UK and EU, explicit consent is generally required for marketing email, with a limited exception for existing customers and similar products (the “soft opt-in”). The UK’s CAP Code rules on use of data for marketing require marketers not to send persistent, unwanted communications. If your list includes European subscribers, get advice from a privacy professional in that market.
Tracking pixels are under the microscope
Personalization often depends on pixels that record opens and clicks. In 2025 the French regulator CNIL put out draft recommendations on tracking pixels in emails. They suggest that pixels used to personalize content or adjust frequency need prior explicit consent, while anonymous measurement of overall open rates can be an exception. That’s a French position, but it signals where privacy rules are heading. Build your targeting on data people knowingly gave you: purchases, preferences, onsite actions.
A four-week plan to get started
Week 1: Audit. Export your list with purchase and engagement data. Remove hard bounces. Define your five starting segments and write down one goal for each.
Week 2: Build the first two flows. Usually a welcome series and an abandoned cart flow. Write short emails with one action each. Check that each links to a page that continues the message.
Week 3: Launch and add a test. Pick a single variable, such as the subject line of the first welcome email, and split the segment evenly.
Week 4: Read, record, repeat. Judge the test on clicks or conversions. Record the winner. Start the post-purchase flow and queue the next test.
After the first month, review quarterly: retire segments that overlap, split the ones that are too broad, and refresh any flow that has gone stale.
FAQ
What is the difference between targeted email and segmented email?
Segmentation is the method: dividing your list into groups. Targeting is the broader goal: getting the right message to the right person, whether through segments, triggers or individual personalization. Most targeted programs start with segmentation and add triggers.
How many segments do I need?
Start with three to five that you can act on right away, such as new subscribers, cart abandoners, first-time buyers, loyal customers and lapsed contacts. Add more only when you have the content and the volume to test them. Small segments with no tailored message add work and no value.
How often should I email a targeted segment?
There is no universal number. Small-business guidance often suggests roughly 4 to 8 emails per month, and flows follow their own timing. Watch unsubscribe rates, spam complaints and click rates by segment, and lower frequency for groups that start to tune out.
Is targeted email marketing legal for B2B in the US?
Yes, but CAN-SPAM applies to B2B email as well as consumer email, according to the FTC. You need accurate headers, honest subject lines, a physical address and a working opt-out. If you email recipients in the UK or EU, different consent rules apply.
What is the 60/40 rule in email?
It is a content guideline: roughly 60% of your emails provide value, such as tips or useful stories, and 40% promote or ask for action. It is a rule of thumb for sequence design, not a legal requirement, and you should adjust it to what your own segments respond to.
