Are you getting reactions that users didn't click?
This can be caused by email scanning services (for example Barracuda) that automatically follow all links in sent or received emails to check for security risks.
When a scanning service follows a link it appears the same as if a user had clicked that URL, and this triggers a reaction.
If you suspect this is happening but aren't sure please contact email@example.com, we are happy to investigate.
Whitelisting SmileBack to prevent false reactions
You can often prevent this situation by whitelisting SmileBack with your email scanning service or that of your client. This means the email scanner will skip links from SmileBack.
Find the whitelist (it may be called something different, like "trusted domains") in your scanning service and add "feedback.smileback.io" to it.
