Bounce Rate Reduction
Bounce rate is the percentage of emails that fail to deliver. A hard bounce means the email address doesn't exist. A soft bounce means the mailbox is temporarily unavailable. For cold outbound, bounce rate above 2% damages your sending domain reputation, which kills deliverability for every future email you send.
The principle: every bounce is preventable. Verify before you send. A $0.005 email verification check prevents a $500 domain reputation recovery process. The math is obvious. Verify every email.
