What are Best Practices for Preventing Non-Existent Addresses?
Preventing non-existent addresses from entering your list is key to maintaining its quality. Here are some best practices: - Use Captcha: Implementing CAPTCHA on your signup forms can prevent bots from submitting invalid email addresses. - Double Opt-In: As previously mentioned, a double opt-in process can help verify the validity of email addresses. - Regular Validation: Periodically validate your email list to catch and remove non-existent addresses. - Engagement Monitoring: Regularly monitor engagement metrics to identify and remove inactive subscribers.
