Add CAPTCHA to Your Sign-Up Forms
CAPTCHA helps protect your sign-up forms from spam and bot submissions by verifying that real people are subscribing to your list. This keeps your subscriber data clean and improves your email deliverability.
What is CAPTCHA?
CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security feature that challenges users to complete a task that’s easy for humans but difficult for automated bots. This prevents fake sign-ups and spam submissions.
Why use CAPTCHA?
- Prevent spam sign-ups – Block bots from submitting fake email addresses or phone numbers to your forms.
- Protect your sender reputation – Keeping spam addresses off your list helps maintain good deliverability and reduces bounce rates.
- Maintain list quality – Ensure your subscriber list contains only real, engaged users who genuinely want to receive your messages.
- Reduce costs – Avoid paying for fake subscribers or wasting resources sending messages to invalid addresses.
How to enable CAPTCHA
To add CAPTCHA protection to your sign-up forms:
- Navigate to the form you want to protect
- Go to the form’s Design section
- Click on Settings
- Mark the “Use google reCAPTCHA” option as active
- Save your changes
How Google reCAPTCHA works
Google reCAPTCHA analyzes user behavior and interactions to determine if the submission is from a real person or a bot. In most cases, it works invisibly in the background without requiring any action from the subscriber. If suspicious activity is detected, users may be asked to complete a simple challenge to verify they’re human.
Best practices
- Enable on public forms – Always use CAPTCHA on forms that are publicly accessible or shared widely online.
- Test your forms – After enabling CAPTCHA, test the sign-up process yourself to ensure it works smoothly and doesn’t create friction for legitimate subscribers.
- Monitor form submissions – Keep track of your form submission rates after enabling CAPTCHA to ensure it’s not blocking too many legitimate subscribers.
- Use on high-traffic forms – Forms that receive a lot of traffic are more likely to attract spam, making CAPTCHA especially important.
