Preventing spam and bot attacks involves multiple strategies:
Use double opt-in for email subscriptions to ensure genuine sign-ups. Implement CAPTCHAs on sign-up forms to deter bots. Regularly clean your email list to remove inactive or suspicious addresses. Monitor engagement metrics for unusual patterns that may indicate bot activity. Use email authentication protocols like DKIM, SPF, and DMARC to protect your domain from being used in spam or phishing attacks.
