How do I re-engage dormant customers?

I'm struggling with a significant number of customers who have made a purchase in the past but haven't returned to my online store in months. These dormant customers represent a potential revenue opportunity that I'm currently missing. I want to understand the most effective strategies for rekindling their interest, bringing them back to my store, and converting them into active buyers again. What are the most successful approaches to customer reactivation that can help me turn these inactive customers into repeat purchasers?

TL;DR - Quick Answer

Calculate return on ad spend (ROAS) as: Revenue from ads / Ad spend. A 4:1 ROAS (400%) is a common minimum target, meaning you earn $4 for every $1 spent. However, ROAS alone is misleading without knowing your margins - a 4x ROAS on 25% margin products barely breaks even.

How Do I Calculate Return on Ad Spend (ROAS)?

ROAS is the most commonly used paid advertising metric in e-commerce, but also one of the most misunderstood. A "good" ROAS number varies dramatically depending on your margins, business model, and whether you're measuring new vs returning customer revenue. Understanding what ROAS number you actually need is more important than chasing industry averages.

ROAS vs MER (Marketing Efficiency Ratio)

ROAS Limitations

Platform-reported ROAS counts sales influenced by ads, often including customers who would have purchased organically anyway. Attribution windows and cross-channel effects make pure ROAS unreliable for total efficiency measurement.

MER (Marketing Efficiency Ratio)

MER = Total revenue / Total marketing spend. This blended metric avoids attribution issues by measuring overall marketing efficiency across all channels simultaneously. Most operators target 4-8x MER depending on margins and growth stage.

New Customer ROAS

Separate your ROAS for new vs returning customers. Returning customers who bought through a retargeting ad might show high ROAS, but they may have purchased anyway. New customer ROAS is the true efficiency measure of customer acquisition.

ROAS Amplification Through On-Site Conversion

Growth Suite Trigger Campaigns increase the revenue extracted from every paid visitor by recovering walk-away visitors who would otherwise leave without buying. If your ads drive 1,000 visitors at $1 each ($1,000 spend) and you normally convert 3% ($30 orders = $900 revenue = 0.9x ROAS), recovering an additional 10% via exit-intent at $30 AOV adds $300 revenue to the same $1,000 spend - improving ROAS from 0.9x to 1.2x without changing a single ad.
