Assuming I create and import a list of participants and add a field called "end-url" and populate that field with different URL's for each participant.
Can I use the expression manager to either:
1) redirect them to the custom URL contained in their record under the field called "end-url" (preferred) or
2) send them an email thanking them for their participation and including in that email, the personalized end url created from the field for their record "end-url"?
Yes, I'm answering my own question: this is very easy. you just create an attribute_1 for the participants and then fill that in with what you want. Then, you include that {attribute_1} in the "confirmation" email which is sent to anyone who competes the survey and your individualized URL will be included therein.
