Viber Campaign ROI: What every e-shop should track

You're sending campaigns. Can you prove they work?

Every Viber campaign you send costs money. The question isn't whether customers are opening your messages — with 98% open rates, they almost certainly are. The question is whether those opens are turning into orders you can measure.

Most e-shop owners running Viber campaigns face the same problem. You send a flash sale on Monday, and Tuesday's revenue is up. But was it the campaign? Or was it organic traffic, a Google ad, a returning customer who would have bought anyway? Without direct attribution, you can't tell. You look at total revenue and try to connect the dots retroactively — and that's not measurement, it's guesswork.

This matters more than it seems. If you can't tell which campaigns actually generate revenue, you can't decide which ones to repeat, which audiences to invest in, or whether your messaging spend is justified. You might be scaling campaigns that barely break even and ignoring the ones that quietly drive most of your sales. For any e-shop on Shopify, WooCommerce, Magento, or a custom platform, this blind spot turns every campaign into a gamble instead of an informed investment.

The metrics that actually tell you if it's working.

Every Viber campaign you send creates a funnel — from messages delivered to revenue earned. Tracking each step tells you not just whether a campaign worked, but exactly where it worked and where it didn't.

Messages Sent & Delivered is where everything starts. How many messages did you send, and how many actually reached your customers? The gap between sent and delivered tells you about the quality of your contact list — invalid numbers, unsubscribed users, or delivery failures. If you're paying to send 5,000 messages but only 4,200 land, you need to know that before anything else.

Viber Opens & Open Rate tells you whether your messages are being seen. With Viber's typical 90–98% open rates, this number should be high — but it's still worth tracking per campaign. A drop in open rate might signal message fatigue, poor timing, or an audience segment that's disengaging. It's your first signal that something in the campaign needs attention.

Unique Clicks, CTR & CTOR measure whether your message drove action. Click-through rate (CTR) shows clicks as a percentage of messages delivered — your overall campaign reach-to-action ratio. Click-to-open rate (CTOR) shows clicks as a percentage of opens — how compelling your content was to people who actually saw it. A high open rate with a low CTOR means your message landed but your offer or creative didn't convert. These two metrics together tell you whether the problem is reach or relevance.

Attributed Orders is where the funnel crosses from engagement into revenue. This is the count of orders that trace directly back to a specific campaign — not total store orders that day, not orders you hope were related, but orders you can prove came from this send. It's the metric that separates real attribution from guesswork.

Attributed Revenue puts a euro value on those orders. Your campaign drove 86 orders — but were they €15 orders or €120 orders? Attributed revenue answers that and gives you the top-line number that justifies your messaging investment. Combined with attributed orders, it also gives you your Average Order Value per campaign — showing whether you're driving big baskets or small ones, and which campaign types consistently push customers toward higher-value purchases.

Messaging Cost is what you actually spent to send the campaign — the total cost of delivering those Viber messages. This is the denominator in every profitability calculation. Without knowing your exact cost, you can't calculate ROI, cost per sale, or whether scaling a campaign makes financial sense.

Cost per Sale divides your messaging cost by attributed orders. If you spent €200 and drove 50 orders, each sale cost you €4. Compare that to your profit margin and you know instantly whether the campaign was profitable. This is the metric that tells you whether to scale aggressively, optimise, or stop.

Revenue per Recipient divides attributed revenue by total recipients. A campaign that earns €2,000 from 200 VIP customers (€10 per recipient) tells a completely different story from one that earns €2,000 from 5,000 people (€0.40 per recipient). Same revenue, different economics. This metric reveals targeting quality — and whether you're getting the most from every send.

Campaign ROI is where it all comes together. Revenue earned divided by messaging cost. If you spent €150 and drove €3,000 in attributed revenue, your ROI is 20x. This single number tells you whether the campaign earned its keep — and when you compare ROI across campaigns, you immediately see which promotions, audiences, and messages generate the best returns.

Beyond individual campaigns, you should also track daily trends — revenue, orders, and costs plotted over time — to spot patterns like which days perform best and whether increased spend correlates with increased return. And audience health — active buyers, dormant contacts, new sign-ups — to know whether your Viber channel is growing or quietly shrinking.
