## Email Verification: Non-Negotiable

Never send to unverified email addresses:

| Verification Level     | What It Checks | Bounce Rate Result |
| ---------------------- | -------------- | ------------------ |
| None                   | Nothing        | 10-30% (dangerous) |
| Syntax check           | Valid format   | 5-15%              |
| Domain check           | Domain exists  | 3-8%               |
| Mailbox check          | Mailbox exists | 1-3%               |
| Real-time verification | Delivered test | Under 1%           |

**Why Verification Matters:**

* Email deliverability depends on sender reputation
* High bounce rates trigger spam filters
* ISPs penalize senders with bounces
* Can get your domain blacklisted
