What is the purpose of reminder emails in survey distribution?

The purpose of reminder emails in survey distribution is to encourage participants who may have overlooked or forgotten to complete the survey after the initial invitation. Sending a reminder can significantly improve response rates, as it prompts recipients to take action on something they may have intended to do but have not yet completed. This strategic communication helps to ensure that the survey reaches a broader audience and that more data can be collected to achieve more reliable insights.

The other options do not align with the function of a reminder email. Summarizing survey results is not the intent of a reminder email, as this is typically done after data collection is complete. Thanking participants for their responses is a post-survey action, not a reminder for those who have yet to participate. Changing survey questions is a process that occurs prior to distribution and would not be relevant or appropriate in the context of a reminder email.
