+{/* MANUAL-CONTENT-START:intro */}
+ZeroBounce is a real-time email validation and deliverability service. Use this integration to validate individual email addresses before outreach — it flags invalid, catch-all, spamtrap, abuse, and do-not-mail addresses so you can drop risky contacts and protect your sender reputation — and to check the validation credits remaining on your account. ZeroBounce is the default verifier behind many email-finding waterfalls.
