Measuring ROI is based on comparing sending costs with the revenue generated by the campaign. The most accurate method is using unique discount codes and links with UTM parameters, which allow you to track traffic and sales directly in Google Analytics 4. With SMSAPI analytics, you can see exactly how many customers clicked the link, enabling precise optimization of future marketing budgets.
Traditional SMS doesn't support images, but you can send them via MMS messages or – a more cost-effective and popular choice – by including a shortened link (e.g. idz.do) in the SMS content that leads to a mobile landing page. Such a page can contain images, videos, or a full product list. For the most demanding brands, the RCS standard is available, allowing multimedia to be sent directly within the chat window.
The optimal time to send SMS depends on the industry. In e-commerce, the highest open rate is recorded in the afternoon hours (5:00–7:00 PM), when customers have time to browse offers on their smartphones. For B2B, it's best to target weekdays during standard working hours. The key to success is analyzing past campaigns and A/B testing different times to match the daily rhythm of your specific target audience.
An effective promotional SMS must be concise (the standard is 160 characters) and include: your own sender field (SMS branding), a unique value proposition such as a discount code or sale information, a clear CTA, and a shortened link leading to the landing page. Personalizing the message, for example by using the customer's first name, makes the campaign feel more direct, which significantly boosts conversion.
Planning an SMS campaign starts with defining a clear goal, such as promoting a new collection or sending discount codes, and segmenting your contact database. Next, you prepare content with a specific benefit and a call to action (CTA), and choose the optimal sending time. Remember to send a test message to yourself first. This way, you can check the text's appearance and the correctness of the links before sending it out to customers in bulk.
