I need to add a solid captcha to my various subscription forms as they are being abused by spammers who are submitting random people’s email addresses. I currently have about 60K subscribers on my list.
(What happens next is that these random people receive a subscription confirmation email, which they report as spam because it’s technically unsolicited, and this is terrible for my deliverability and my standing with Amazon SES. Currently on probation in one US region. )
So. I want to integrate Recaptcha into my subscription forms to prevent that abuse. (I have seen the captcha plugin, but it’s Recaptcha I would like to use for optimal user experience.)
Any thoughts or experience to share?
