Alex should use the Segmentation strategy to achieve his goal. Here's how he can do it step by step:

1. Identify Different Customer Groups: Alex needs to first identify the different groups of customers that his software company serves. These groups can be based on various factors like the type of software they use, their usage patterns, their industry, etc.

2. Understand Customer Needs: Once the customer groups are identified, Alex needs to understand the specific needs and preferences of each group. This can be done through surveys, customer feedback, and analyzing customer behavior.

3. Create Customized Messages: Based on the understanding of each customer group, Alex can now create customized SMS messages that are relevant to each group. These messages should address the specific needs and preferences of each group.

4. Test and Refine: After sending out the messages, Alex should monitor the response of each customer group. Based on the response, he can refine his messages and segmentation strategy to improve effectiveness.

Remember, while segmentation is the key strategy here, the other options mentioned - sending short & concise messages and adding a clear CTA (Call To Action) - are also important and should be incorporated in the SMS messages.
