I'm working on a project that requires generating unique survey links for each participant, allowing for panel and longitudinal data collection without needing their email addresses. This is crucial for tracking responses over time in a longitudinal study. While platforms like QuestionPro offer these capabilities, they're prohibitively expensive due to USD-based pricing, especially for individual students. Moreover, their data analysis features are often unnecessary, as I plan to use statistical software like SPSS, SmartPLS for analysis.
I shall be sincerely thankful for recommending an affordable alternative that supports individual tracking and diverse dispatch options like WhatsApp or SMS, essential for reaching participants in the developing world ? Your guidance would be invaluable for my 3-phase study.
