Email Subscribers does various form validation checks included in the script, but we offer additional options to prevent spammers from abusing the subscription forms and for better protection under Email Subscribers > Settings > Security.
Note: Options #2, #3, and #4 are available with paid plans.
- Enter the domain names from which you have a high number of spammers or the domains that you suspect, e.g., mail.ru in the Blocked Domain(s) box to block them
- Enable Block Known Attackers to automatically block known attackers who match our database
- Make sure Fake Emails is checked to automatically block fake emails
- Finally, enable Captcha to show the captcha field on your subscription forms
Following the above steps greatly reduce the number of spammers and help you have a peace of mind.
