SMS Marketing Performance: 8 Metrics Every Australian Business Should Be Tracking in 2026

You hit the send. The campaign goes out. A few replies trickle in. Maybe a sale or two follows.

But here's the honest question. Do you know if that campaign worked? Or are you just assuming it did because SMS marketing feels like it should perform?

Most businesses stop at "messages delivered" and move on. But delivery is the starting line, not the finish.

SMS marketing solutions give you more data than most channels. The problem is knowing which numbers matter. These 8 metrics will tell you where your campaigns are winning, and where they are bleeding money.

Delivery Rate

Delivery rate measures what percentage of your sent messages reached a recipient's handset. A healthy rate is above 95%. Anything below 90% signals that your contact list needs attention. Outdated numbers, duplicates, or inactive handsets are likely pulling them down.

Business SMS marketing solutions with real time delivery reports let you watch each message move from "sent" to "delivered" as it happens. That visibility matters more than most people realise, because a low delivery rate inflates every other metric you track.

Open Rate

SMS marketing has an open rate that far outperforms email. But SMS does not track opens the way email does.

What you can measure is an inferred open rate. How quickly recipients responded, clicked a link or redeemed an offer after your message went out. Response speed is a reliable proxy for whether your message was read.

Using an Alpha Tag (your brand name as the sender ID) directly influences this. This is because people are far more inclined to open and take action on a message when they recognise the sender's name. It is a small setup decision that compounds across every campaign.

Reply Rate

The reply rate is the metric that separates enterprise SMS marketing from broadcast only channels. It measures inbound replies against total messages sent and tells you whether your call to action was clear enough to prompt a response.

A low reply rate on a campaign designed to generate responses points to one of three things. The message copy, the timing or the offer itself. Knowing which one requires testing but reply rate is what flags the problem in the first place.

Click Through Rate

When your SMS marketing campaign includes a URL, click through rate (CTR) to show how many recipients took the next step.

To track it properly, attach UTM parameters to your shortened link. This connects your SMS activity to your website analytics and isolates exactly what traffic that campaign generated. The benchmark varies by industry, offer type, and send time.

Keyword Conversion Rate

If your campaigns use keywords like "Reply YES to confirm" or "Text DEAL to claim your offer", the keyword conversion rate tells you how many people followed through. It is particularly useful for opt in campaigns, competitions and sequenced messaging flows.

A low conversion rate on a keyword campaign usually means the trigger word was unclear, or the value exchange was not compelling. SMS marketing solutions with built-in auto responder functionality log these responses automatically, so the data is there without any manual tracking.

Opt Out Rate

Under the Spam Act 2003, Australian businesses must include opt out instructions in every SMS marketing message and honour those requests promptly. So opt out rate carries both compliance and strategic weight.

A spike in opt outs typically points to message frequency being too high, content being off-target or poor send timing. Treat it as direct audience feedback. Opt-out management should be fully automated. When someone replies to STOP, END or UNSUBSCRIBE, that number should be flagged and suppressed from all future sends immediately.

Response Velocity

Response velocity measures how quickly your audience acts after a campaign goes out. For business SMS solutions sending large lists, this metric has an operational dimension too. A sudden wave of responses is great until it overwhelms your team or call centre.

Track velocity across campaigns and patterns emerge: which send times produce faster responses and which audience segments take longer to act. That knowledge directly improves your next campaign.

ROI

Revenue from campaign	Total sales or conversions attributed to the SMS
Cost of campaign	Total SMS credits used × cost per credit
ROI formula	(Revenue ÷ Cost) × 100

For enterprise SMS marketing, this calculation matters most when justifying spend across large lists or multiple concurrent campaigns. Track it consistently and you build an evidence base for where SMS sits in your broader marketing mix.

Frequently Asked Questions

1. How often should I be checking my SMS campaign metrics?

Check delivery rate and reply rate within the first hour of sending. That is when anomalies show up. Review CTR and keyword conversion rate at 24 and 72 hours. ROI is best assessed after your campaign's intended action window closes.

2. Can I track SMS marketing performance without a dedicated platform?

Technically, yes, but it becomes manual and unreliable fast. Spreadsheet tracking misses real-time delivery data and cannot automate opt-out suppression. A purpose-built platform gives you accurate, centralised reporting without the admin overhead.

3. What is a realistic ROI benchmark for SMS marketing campaigns in Australia?

There is no universal figure. It depends heavily on your industry, offer and list quality. The more useful approach is tracking your own campaign-over-campaign ROI to identify your personal baseline and measure improvement from there.

4. Does personalisation affect reply rate or is it just a nice-to-have?

It measurably affects reply rate. Including a recipient's first name in the opening of a message has been shown to increase response rates. It signals the message was intentional, not mass-broadcast and that distinction matters to how people respond.

5. Is there a point where tracking too many metrics becomes counterproductive?

Yes. Tracking eight metrics across every campaign adds noise if you have not established baselines yet. Start with delivery rate, reply rate and ROI. Add the others once you have enough campaign history to make comparisons meaningful.
