Most companies do not analyse SMS marketing conversions – shows our report “SMS Communication in Poland”. Those that care about the campaigns’ effectiveness measure it using the CTR (click-through rate) of the link in the message, average sales increase or the percentage of discount codes used. What factors should you consider to call a campaign successful? Read about KPI in SMS marketing.
Since we’ve switched from SMS or phone calls to instant messaging via WhatsApp or Messenger, we do not hear an incoming SMS signal so often. Nevertheless, a new text message notification still reminds us of something important and urgent.
As a result, the open rate of SMS messages is still high (up to 98%), and most people read text messages up to 5 minutes after receiving them. However, this is only half of the success. Apart from the Open Rate, it is also worth knowing other possibilities of assessing SMS marketing‘s effectiveness.
SMS KPI: delivery rate
A good and well-maintained customer database can serve for years, but many people can change the phone number or lose interest in the offer during this time. Thus, it’s worth comparing lists of sent and delivered messages. We recommended running such checks regularly to keep your database effective and to lower the cost of conversion.
- Are there returning customers in my database?
- Do I personalize messages by interests and/or preferences?
- Are the buyers interested in purchasing my product again?
- What would make them comeback?
Checking if the number is active is possible thanks to the HLR (Home Location Register) function, making it easier to exclude invalid contacts and check the registry of a number in the appropriate GSM network. Furthermore, it’s also worth knowing the recipients’ preferences. It’ll help to personalise the content of the SMS message.
The easiest way to get to know the preferences of your customers is by doing a short survey. You can also collect all data automatically during signup by using the Newsletter SMS widget. Both methods target future campaigns according to specific parameters, e.g., gender, age, shoe size, and tailoring content and offer to particular groups. Such SMS campaigns are more effective.
SMS KPI: opt-out rate
The Opt-Out rate is the number of people who unsubscribed divided by the number of all contacts. It allows you to easily define a group of recipients who are not interested in receiving your messages. Although it might seem not reasonable, it’s best to present them with a way to unsubscribe from the newsletter.
A personalised Opt-Out link attached to an SMS allows the unsubscribe from the database and excludes future campaigns. Removing uninterested, unhappy people favours the effectiveness of the database, advertising budget, and brand image.
SMS KPI: conversion rate
You should start to monitor the response of the recipients as soon as the SMS campaign hit their phones. It is crucial to know how many messages were opened, but the number of people who clicked the link inserted in the SMS can help to measure the effectiveness better. In other words – it’s worth checking CTR (Click-through Rate).
Our report from 2017 shows that about 40% of companies
Similarly to e-mail campaigns, the primary determinant of bulk SMS effectiveness is a conversion rate. This indicator shows how many recipients made the purchase and became customers after the campaign.
One way to estimate it is to track traffic intensity in e-commerce, e.g., in Google Analytics and compare it with the same time interval for previous days or with average traffic for that day of the week.
You can track the SMS campaign’s effectiveness by adding UTM parameters containing the medium type and campaign name in the link and then shortening it with a tool such as cut.li. These two actions help to measure the number of clicks but also shortens the message.
How to add UTM parameters to shortened links?
The same can be achieved in retail stores using a discount code or coupon in the message, which can be generated online and shown while purchasing. However, be sure to use the code only in the SMS campaign, so you will quickly check its effectiveness.
Key performance indicators or simply KPIs give a glance at whether the direction chosen in the marketing strategy meets with a positive market reaction, whether the tools selected to achieve this goal are correct, and the messages are appropriate for customers.
Without the knowledge provided by the conversion rate, CTR or Opt-Out, the marketer would have to rely solely on intuition and could not seek or eliminate his actions’ weaknesses. That is why you should measure and test your campaigns.
