Yes, I realized it wasn’t working when testing while logged into admin in WordPress. It works when I’m logged out.
A follow-up question I have though is whether it’s possible to integrate 3rd party Captcha systems like hCaptcha or reCaptcha?
Also, in your opinion, for security measures, is a Captcha page for Newsletter an adequate substitute for double opt-in? I’ve noticed many subscribers miss the confirmation email with double opt-in, although it has prevented bots. I’m just wondering if choosing a single opt-in + Captcha combo would be a better strategy for keeping away spam and also ensuring subscribers get the welcome email.
Thanks!
