What is Google reCAPTCHA?
Google
reCAPTCHA is a free service that protects your website from spam and abuse. It uses advanced risk analysis techniques to tell humans and bots apart. In the context of
email marketing, it helps ensure that only legitimate users are signing up for your newsletters and promotional emails.
reCAPTCHA v2: Users are prompted to click a checkbox that says "I'm not a robot."
Invisible reCAPTCHA: The verification process runs in the background without user interaction unless deemed necessary.
reCAPTCHA v3: This version provides a score based on user behavior, requiring no user interaction.
Register your site on the
Google reCAPTCHA website.
Get the site key and secret key provided by Google.
Add the reCAPTCHA widget to your sign-up form using the site key.
Verify the user's response on your server using the secret key.
Many
email marketing platforms offer built-in integrations for Google reCAPTCHA, making the implementation process straightforward.
