Hey @tonygao,
We’re sorry to hear that you’ve encountered spam issues.
If you’re still getting spam emails, you can consider the following alternative options:
In WPForms Lite, we have a built-in anti-spam option which is enabled by default in the form builder > Settings > General (see screenshot here).
We also have integration with Google’s free reCAPTCHA service. In case it helps, here’s a detailed tutorial on how to set up reCAPTCHA in WPForms.
Alternatively, you can consider the third-party plugins such as WordPress Zero Spam or Spam protection, AntiSpam, FireWall by CleanTalk which work out of the box to protect your forms against spam.
Hope this helps!
