The Hidden Risks of Skipping a Test Plan
- Wasted Budget: Investing in creative, printing, and postage without knowing what works.
- Missed Learnings: Passing up the chance to collect insights and behavioral data that inform future campaigns.
- Reinforcing Poor Performance: Repeating tactics that underperform because no control comparison exists.
When You Test Strategically, You Market Intelligently.
sg360° transforms testing into a data-backed decision engine, then gives you a strategic roadmap to learn what works and improve outcomes with every campaign.
Defining test objectives
We start by asking What are we trying to learn and then set primary objectives per test to keep analysis focused and actionable. Whether you’re optimizing for conversions, reactivation, AOV, or customer lifetime value, we begin with crystal-clear goals aligned to your KPIs.
Determining measuring device / response mechanism
How we measure matters, so we select tools that give clear, attributable results, such as QR codes, personalized URLs, tracking phone numbers, and offer codes. We help you choose the right response mechanisms to measure campaign success with precision.
Defining test cells (list, creative, messaging, offers)
A test cell is a group of recipients who receive a specific version of your campaign. Our testing matrix includes the right mix of variables: lists, creative concepts, offers, formats, messages, etc. for meaningful comparisons that deliver actionable insight. We consider what elements we’re testing and determine what kind of test we need in order to get the best read per campaign to optimize the results.
Defining test method & assumptions
This is where test design meets data science as we determine the sample size, confidence level, holdout groups, and measurement period. Our strategists apply sound statistical principles to determine sample size, confidence thresholds, holdout cells, and more – so you’re testing smarter, not just more.
Defining execution channels
Because direct mail excels when part of an omnichannel campaign, a multi-channel test gives us insight into how audiences behave across different platforms and what combination of channels works with each target segment. Whether you’re testing within direct mail or across channels (email, digital display, social) we build tests that reflect today’s omnichannel consumer journey.
Documenting Test Design
We capture all elements in a centralized document to prevent scope drift, keep execution aligned across teams, and ensure the test can be replicated or scaled. Your comprehensive test blueprint outlines every detail, from setup to measurement, to ensure alignment, streamline execution, and preserve data for future testing.
