Sending to unverified emails is the fastest way to destroy your sender reputation. Every bounce damages your domain's standing with Gmail/Outlook/etc., dropping inbox placement for ALL future sends — not just the current campaign.
The bounce-rate threshold
Gmail flags senders at >5% bounce rate. Above 10% you're effectively in spam folders for weeks. Above 20% your domain is burned.

Sender reputation recovery
Takes 30-90 days of clean sending from a fresh domain to recover. Most teams don't recover the original domain — they buy a new one and start the warmup process.
Catch-all trap
Catch-all servers accept every email, so verification falsely passes. Real mailbox doesn't exist → still bounces. Always flag + filter catch-alls separately.
