I understand the effectiveness of re-targeting if used properly. However, I can't figure out how to implement it on Teespring. I understand that we need to paste the re-targeting code into our website, which is not possible in Teespring since we don't have control over the coding of the website. Anyone has an idea on how to implement this? Teespring actually re-targets our audience, but I'm not satisfied with their ad images and ad copies when re-targeting people. Please let me know your thoughts.
