Frequently Asked Questions
Frequently Asked Questions
You can create lists of words or patterns to block. If a submission contains a blocked word (like spammy keywords or profanity), it's automatically filtered into your spam folder without the user ever knowing.
Yes. Use the Email Blocklist to stop accepting submissions from specific domains (e.g., `*@company.com` for internal forms).
A honeypot is an invisible field added to your form. Bots often fill it out, while humans do not. Any submission where the honeypot field is filled is automatically flagged as spam.
No. All these checks happen silently in the background. Legitimate users will never see any warnings, or errors caused by these systems. Only you see the filtered results.
Absolutely. These tools are designed to work together. For example, you can set a strong Spam Defense level and add a Keyword Denylist for extra protection against specific threats.
