Key facts
- Buzzlist includes standard email verification with paid contacts, checks status again before Buzz Send sends, and skips addresses that do not pass.
- In small numbers, and only when the person clearly fits.
- Send to valid, hold catch-all and unknown, drop invalid.
- The domain accepts mail for any address, so a check cannot confirm the person.
What do verification results mean?
- Valid: the mail server accepted the address in a check.
- Catch-all: the domain accepts every address, so the check cannot tell.
- Unknown: the server did not answer clearly.
- Invalid: the address will bounce.
No check guarantees delivery.
Should I send to catch-all addresses?
In small numbers, and only when the person clearly fits. Buzzlist never calls a catch-all address verified.
How to check addresses before sending

Typos, role inboxes you do not want, duplicates.
- Run a verification check
Paid Buzzlist contacts include one.
- Split by result
Send to valid, hold catch-all and unknown, drop invalid.
- Watch bounces
Stop if bounces climb toward 5 percent.
When does Buzzlist fit, and when does it not?
It fits when
- You want checks built into the list and the send.
It does not fit when
- You need to verify a huge list you already own without sending through Buzzlist.
