The idea: each answer adds a tag to the respondent's contact record; a segment “list you sent to, without this tag” gives you the ones still missing. The reminder only bothers them.
In three steps
- In the survey, link the email question to your contacts and add a tag for the survey (“Feedback received”): connect a survey to your contacts.
- Send the survey in an email campaign: the recipient's address is already filled in.
- A few days later, create the segment “campaign list, without the tag” and send it the reminder.
A survey made non-identifying (no name, no email, no link to your contacts) does not allow this targeting: in that case, send the reminder to the whole list, pointing out that those who have already answered can ignore the message.
More tips for getting more answers: improve survey participation. A complete example with immediate and follow-up evaluation: training satisfaction.
