FormDefender Enhanced Mode
If you have bots attacking your form(s) and injecting fake contacts with real emails into your list, you'll want to use FormDefender's "Enhanced Mode". You're probably seeing something like this:
Important Note when using Enhanced Mode
Before activating or turning on the HTTP Post for Enhanced Mode, you must:
Verify that the FormDefender code is live on your page and tested.
Once confirmed, add the HTTP Post to your automation. Then make sure the box is checked inside your FormDefender settings.
Ensure the FormDefender code and HTTP Post match and are used together.
⚠️ Do not combine or mismatch different configuration codes and HTTP Posts, as this will cause errors.
Need Extra Protection?
If your forms are being maliciously targeted — whether by advanced bots or even humans manually attacking — ListDefender now offers Fingerprinting as an additional safeguard.
When combined with FormDefender in Enhanced Mode, Fingerprinting adds a third layer of protection to lock down your forms even further.
