Omnisend Segmentation: How to Target the Right Subscribers Every Time

Sending the same email to your entire list is the fastest way to erode engagement, inflate unsubscribes, and train your subscribers to ignore you. Omnisend’s segmentation engine is one of the most flexible in the mid-market e-commerce space — and most brands use about 20% of its capability.

This guide breaks down exactly how to use Omnisend’s segmentation tools strategically: the difference between pre-built and custom segments, how to build RFM-based targeting, how to combine SMS and email segments, and the segmentation mistakes that consistently hold brands back.

Pre-Built Segments vs Custom Segments in Omnisend

Omnisend ships with a library of pre-built segments designed around common e-commerce use cases. These include segments like “Active subscribers” (opened or clicked in the last 90 days), “Lapsed subscribers” (no engagement in 90+ days), “New subscribers” (opted in within the last 30 days), and purchase-based groupings.

Pre-built segments are a good starting point, but they are not a segmentation strategy. They are generic by design. Where Omnisend becomes genuinely powerful is when you build custom segments using the platform’s multi-condition builder.

Custom segments in Omnisend combine conditions across three data layers: contact properties (email address, custom fields, tags, opt-in source), behavioural data (opens, clicks, website activity, product views), and e-commerce data (order history, total spend, product categories purchased, average order value).

You can stack conditions using AND/OR logic, making it possible to build segments like “Has purchased in the last 60 days AND average order value over $80 AND has not opened an email in the last 30 days.” This level of precision is where segmentation starts driving meaningful revenue differences.

Building RFM-Based Segments in Omnisend

RFM — Recency, Frequency, Monetary — is the most proven framework for e-commerce customer segmentation. Omnisend does not have a native RFM module, but you can replicate all the core RFM segments using its custom segment builder.

Champions

Segment definition: Purchased within the last 30 days, has made 3 or more orders, and total spend is in the top tier of your customer base. These are your best customers. Send them early access, exclusive content, and loyalty rewards. Do not send them generic promotional emails — they are beyond that stage of the relationship.

Loyal Customers

Purchased within the last 60 days, 2+ orders, above-average AOV. These customers buy regularly but are not yet in your highest tier. Focus on deepening the relationship with cross-category recommendations and referral incentives.

At-Risk Customers

Made a purchase, but last order was 90–180 days ago. This is the segment that separates proactive brands from reactive ones. Send win-back content before these customers fully lapse. A targeted email addressing their specific purchase history — “It’s been a while since you picked up [product]” — outperforms any generic re-engagement offer.

One-Time Buyers

Purchased exactly once, more than 60 days ago. The goal here is to convert them to repeat buyers. Identify what they bought and send targeted cross-sell or replenishment emails. In Omnisend, you can filter by specific product categories to make this hyper-relevant.

Lapsed Buyers

Last purchase over 180 days ago. These contacts need a re-engagement sequence or suppression. Before writing them off, test one strong win-back campaign with a compelling offer. If they do not respond, move them to a suppression segment to protect your deliverability.

Engagement Scoring in Omnisend

Omnisend tracks email engagement natively. You can segment by whether a contact has opened, clicked, or ignored your last N campaigns. This data is the foundation of engagement-based segmentation.

Build three engagement tiers for your broadcast sends:

Tier 1 (Highly Engaged): Opened or clicked in the last 30 days. Send your full campaigns to this group first. Monitor deliverability metrics here to establish your baseline.

Tier 2 (Moderately Engaged): Last engagement 31–90 days ago. These contacts need more targeted, higher-value content to stay engaged. Reduce campaign frequency slightly and increase content relevance.

Tier 3 (Disengaged): No opens or clicks in 90+ days. Do not include this segment in regular broadcast campaigns. Instead, run periodic re-engagement campaigns specifically for this group, and suppress non-responders after 2–3 attempts.

Sending to Tier 3 contacts in every campaign inflates your list size while dragging down your open rates, click rates, and — critically — your sender reputation. The brands with the best deliverability metrics on Omnisend are almost always the ones who actively manage engagement tiers.

Combining SMS and Email Segments

One of Omnisend’s strongest differentiators is the ability to see SMS opt-in status as a segment condition. This opens up multi-channel targeting strategies that are not possible on platforms where SMS and email live in separate tools.

Create a segment that combines email engagement and SMS opt-in status. Example: “Engaged email subscriber AND SMS opted-in.” This is your highest-value segment for multi-channel campaigns — these contacts have told you they want to hear from you on both channels.

For high-ticket promotions, send an email preview 24 hours before the campaign goes live, then send an SMS on launch day to this combined segment. The overlap of both channels for your most engaged contacts creates a compounding effect that consistently outperforms single-channel sends.

Conversely, build a segment of “SMS opted-in only” — contacts who gave a phone number but have low email engagement. These subscribers may respond better to SMS as the primary communication channel. Adjust your strategy accordingly rather than treating all subscribers identically.

Lifecycle Stage Segments

Every e-commerce subscriber is somewhere on a lifecycle arc: prospect, first-time buyer, repeat buyer, loyal customer, at-risk, lapsed. Omnisend’s segment builder lets you define each lifecycle stage with precision.

Build lifecycle segments based on order count and recency:

• Prospects: subscribed, zero orders
• New buyers: 1 order, within last 60 days
• Developing: 2–3 orders
• Loyal: 4+ orders, purchased within last 90 days
• At-risk loyal: 4+ orders, no purchase in 90–180 days
• Lapsed: any order history, last purchase over 180 days ago

Once these segments are defined, you can suppress them from irrelevant campaigns and target them with lifecycle-appropriate content. A “New buyer” segment gets post-purchase education and cross-sell content. A “Developing” segment gets loyalty programme prompts and bundle offers. A “Loyal” segment gets VIP access and early launch previews.

What Brands Get Wrong About Segmentation

The most common mistake is building segments and not using them. Brands spend hours setting up granular audience definitions, then default to sending every campaign to their full list anyway.

The second mistake is over-segmenting. Having 50 segments does not make your marketing better — it makes it unmanageable. Start with 6–8 core segments that map to your customer lifecycle, master those, and expand only when the data supports it.

The third mistake is never updating segment definitions. A segment built 12 months ago based on “purchased in the last 90 days” is still accurate structurally, but the contacts inside it have changed completely. Segments are dynamic in Omnisend — contacts move in and out automatically — but your logic may need revisiting as your customer base evolves.

Using Custom Fields to Power Deeper Personalisation

Omnisend supports custom contact fields, which let you store data beyond the default profile properties. These fields can come from sign-up forms, integration data, or manual imports, and they can be used as segment conditions.

Examples of useful custom fields: skin type (for beauty brands), pet breed (for pet supply stores), preferred product category (for multi-category retailers), or subscription tier. When a subscriber provides this data at opt-in, you can use it to segment immediately — routing them into tailored welcome sequences and ongoing campaigns that reflect their stated preferences.

From Segments to Revenue: Making It Actionable

Segmentation only creates value when it changes what you send and to whom. The practical application is: for every campaign you plan, ask which segment it is most relevant to, and suppress everyone else.

If you are launching a new skincare product, send to segments that have purchased skincare before or browsed the skincare category. If you are running a high-AOV promotion, send to your Champions and Loyal segments who have already demonstrated willingness to spend at that level. If you are re-running a bestseller campaign, exclude recent buyers of that product.

This discipline — deliberately selecting your audience for every send — is what separates brands generating 35–45% of revenue from email from those stuck at 15–20%.
