Click the Create New Message Template button.

You have 2 options for selecting a template:

1. Send the Post-Event Survey to those who DID NOT REGISTER - useful to send to your no-show list - this option requires a contact list because they are unknown to your registrant database
2. Send the Post-Event Survey to those who DID REGISTER

Select all of the instructional text (highlighted blue in the screenshot below. It will be replaced with a link to your survey.

Click the Survey URLs dropdown menu in the tool bar.

The highlighted text (in the previous step) is replaced by the survey's URL link.

Send a test version to yourself.

When you receive your test message, click the link in the message.  The post-event survey should open in a browser window.

That's it.  Test is complete.  Do not fill-in the survey and Submit it. If you do so, then the recipient will not be able to respond.  Post-event surveys can only be responded to ONE TIME. No ballot stuffing is allowed.

If you need to resend a post-event survey to a few individuals, use a different template: Send to those who did not register and send it to the contact list for those few individuals.
