I am having trouble creating an email campaign that outputs unique survey links. Basically, after I added the contacts by uploading a spreadsheet, I saw the “working” icon, and after that, nothing happened nothing was added.
This usually points to some kind of an issue with the file that you are uploading.
For example, the file might be too large to be uploaded at once – If you have 20,000+ contacts, I would recommend splitting this into at least 2 files and uploading each file.
Additionally, you may need to review your column headers – do your column headers have special characters or HTML?
These are just a couple things to look into.
