A clear measurement framework turns these always-on automations into a reliable, data-backed engine for engagement and retention.

Why Recurring Campaigns Matter

Recurring campaigns, also known as scheduled, periodic, or ongoing automations, are the backbone of CRM. They’re the daily, weekly, or monthly touchpoints that keep your brand in front of customers and your funnel moving. 

Think of: 

  • iGaming: weekly reactivation messages for inactive players
  • E-commerce: replenishment or birthday offers
  • Fintech: monthly account summaries or cashback nudges
  • Retail: loyalty-tier reminders or seasonal updates

They run automatically, building relationships one small interaction at a time. Yet because they run continuously, their results can easily blur together. The real challenge? Seeing what’s working, what’s not, and what deserves more investment. 

Why Measuring Recurring Campaigns is so Hard

Recurring campaigns behave differently from one-time blasts. Their audiences overlap; their effects compound, and small wins stack up quietly over time. 

The biggest mistake is measuring too fast or too slow. Checking too early, and noise looks like failure. Wait too long, and weak automations continue to run. The key is finding balance, structure, patience, and timing. 

Let’s make that real. 

Example: A Weekly Reactivation Campaign

Say you run a weekly reactivation campaign for players who haven’t deposited in seven days. You compare performance to a control group that doesn’t receive the message. 

After six weeks, the data shows: 

  • Week 4 → +3% uplift (not statistically significant)
  • Week 5 → +6% uplift (significant)
  • Week 6 → +5% uplift (significant)

Here’s what that means. The first few weeks lacked sufficient data to be credible. But by weeks five and six, the uplift became consistent and significant—meaning it was statistically reliable, not random. Plus, when using Optimove’s Control Group Optimization, you can dynamically shrink your control group as significant results continue to validate an experiment. 

  • That’s your signal: the campaign is performing, not just fluctuating.

A Framework for Measuring Recurring CRM Campaigns

To evaluate recurring campaigns confidently, you need a structured approach. This framework works across every industry and campaign type. 

  1. Define success early 

    Choose one or two measurable KPIs that connect directly to business outcomes: deposits, purchases, active days, or total revenue. Set those before you launch. 

  2. Plan checkpoints 

    Decide when and how you evaluate results. We recommend: 

    1. Daily campaigns: review after 1–2 days, to assess first after 1–2 weeks, finalize at 1 month
    2. Weekly campaigns: review at 1–2 months, finalize at 3 months
    3. Monthly campaigns: check after 1 month, finalize at 4–6 months
  3. Gather enough data 

    Aim for approximately 500 customers per group and 30–50 measurable KPI events (such as orders, deposits, etc.). 
    If those thresholds aren’t possible, consider dynamically adjusting audience size or consolidating timeframes to maintain statistical reliability. Smaller samples often lead to misleading results. 

  4. Interpret uplift with context 

    Look at performance trends, not isolated weeks. When uplift becomes consistent and statistically significant over several checkpoints, it’s a clear signal to continue. Random spikes or dips are noise, not evidence. 

  5. Act on the evidence

  • Consistent positive uplift → keep and expand
  • Consistent negative → stop and rebuild
  • Inconclusive → keep running until the next checkpoint
  • Long-term inconclusive → treat as a small effect and test a stronger variation

Turning Structured Measurement into Confidence

The real advantage of structured measurement isn’t just better data it’s better decisions. 

By following a consistent framework: 

  • Marketers replace guesswork with evidence
  • Teams align on shared, transparent definitions of success
  • Campaigns evolve based on learning, not instinct
  • Recurring campaigns stop being background noise and become strategic assets that continuously refine and scale themselves.
