Choosing the right targeting criteria is one of the most important decisions before launching an SMS or email acquisition campaign. The same offer can perform very differently depending on who receives it, when, and under what conditions. This article walks you through the practical criteria that typically matter most and how to prioritise them for better acquisition results.
The guidance below focuses on acquisition (prospects acquired through an opt-in audience), not on CRM activity. It emphasises operational choices you can make before sending: target definition, exclusions, timing and simple tests that reduce wasted clicks and improve conversion quality.
1. Start with the offer and the primary KPI
Your offer should drive the targeting. Begin by defining the one main KPI you care about — for example: qualified leads, purchases, trials started, or newsletter sign-ups. Different KPIs favour different targeting trade-offs.
Operational rules to apply:
- If the KPI is low-funnel (purchase, paid conversion), favour tighter relevance: narrower demographics, recent intent signals and smaller volume.
- If the KPI is top-funnel (awareness, newsletter sign-ups), favour broader reach and clear creative with a simple CTA.
- Always align the creative and landing page with the chosen KPI: the user journey must match the promise in the message.
2. Demographics, life stage and household signals
Demographic criteria (age range, gender where relevant, household composition) are quick ways to raise relevance without complex data requirements. For many consumer offers, a sensible age band and household status filter out a large share of irrelevant contacts.
Examples of practical choices:
- Financial products: target age and household income ranges congruent with the product tier and likely affordability.
- Family or childcare offers: include household composition or presence of children where available.
- Retail promotions: use age ranges for categories where purchase likelihood varies significantly by age.
Keep demographic filters conservative at first. Overly tight demographics can reduce scale and inflate acquisition cost per conversion.
3. Geography and timing: local relevance matters
Geography is often underused. Local relevance affects conversion: store availability, delivery options, event dates, language and local pricing all influence user behaviour. Choose geographic granularity based on the proposition — country-wide for digital services, postcode or city for store-based offers.
Timing is equally important. Consider day of week, hour windows and seasonal context. For example, retail promotions often work better during late afternoons and weekends, while professional services may receive more engagement on weekdays.
Operational checklist for geography and timing:
- Match the landing page language and offer details to the selected geography.
- Exclude regions where fulfilment is restricted or delivery costs are prohibitive.
- Use hour-level scheduling to avoid sending outside business hours for conversion-focused offers.
4. Behavioural proxies, recent intent and exclusion rules
Direct behavioural data may be limited on an opt-in audience, but proxies — recent engaged categories, interest segments, or prior web intent — can meaningfully improve targeting. Prioritise signals that tie directly to the purchase trigger for your offer.
Equally important are exclusion rules. Excluding recent purchasers, previous converters, or users who unsubscribed from similar offers reduces wasted sends and improves response quality. For acquisition campaigns, you should also exclude your existing customers to avoid duplicate outreach.
Practical testing approach:
- Create a narrow segment with strong intent proxies and a broader segment with only demographic and geographic filters.
- Run the same creative to both segments and compare click-to-conversion ratios, not just click rates.
- Use exclusions to remove users already converted or who have a recorded opt-out for the channel.
For this type of campaign, DMS Europe can help advertisers select an appropriate opt-in B2C audience, define relevant targeting criteria and route the campaign without delivering the contact file. In practice, this lets advertisers focus on the offer, creative and landing page while DMS Europe manages routing, unsubscribe handling and reporting.
5. Balancing volume versus relevance and a practical checklist
One of the common operational dilemmas is choosing between larger volume and tighter relevance. Higher volume increases reach but can lower conversion quality and waste budget on clicks that do not convert. Tighter targeting typically reduces volume but improves the post-click conversion rate.
Use this practical checklist to decide your initial targeting mix and testing plan:
- Define the primary KPI and acceptable cost per acquisition range.
- Choose an initial target: narrow (high relevance) or broad (reach) based on KPI and budget.
- Set at least two test segments: one tighter (demographics + intent proxies) and one broader (demographics + geography).
- Use the same landing page and creative to compare conversion quality between segments.
- Measure click-to-conversion and cost per conversion after a statistically useful sample — then scale the better-performing segment incrementally.
Finally, remember that targeting is iterative. Start with conservative filters, monitor conversion quality rather than raw clicks, and adjust exclusions and timing based on real campaign feedback. Clear KPIs, a simple test plan and aligned landing pages will usually produce faster, more reliable learning than changing many variables at once.
