No response reminder

This is the reminder for contacts that did not respond to the original invitation. Add the word 'reminder' to the subject line to spur the reader to open the mail. In the email, explain why it is important that the contact responds, why it is relevant to them, and what they will get out of it (better service, an incentive, etc.).

Partial response reminder

For this reminder, the respondent already started to fill out the survey but stopped before finishing. The respondent may have been interrupted or thought the survey was too long. ]

It is important that respondents do not think that this reminder is a 'no response reminder'; otherwise, they won't open it, thinking they already answered that survey. Make sure you set the reminder to be sent very shortly after they first started to fill out the survey (one day is best practice). Modify the subject line, adding something like 'Incomplete:…'. Thank them for their time already. Tell them upfront and in bold that they don't have to start over and that they will return to where they left off.
