What verification checks
A full verification confirms syntax, the domain and its MX records, the mailbox via SMTP where possible, and flags catch-all, disposable and role addresses, plus SPF, DKIM and DMARC at the domain level.
Why it pays off
Removing addresses that would bounce protects sender reputation, improves inbox placement for the rest of the list, and avoids wasted spend on subscriber-priced platforms.
