Frequently Asked Questions
Is B2B cold email legal in the United States?
Yes. Under the US CAN-SPAM Act, B2B cold email outreach to work addresses is legal provided you use accurate sender information, non-deceptive subject lines, a valid physical postal address, and a clear opt-out mechanism.
Do I get charged credits for bounced or catch-all US emails?
No. VerifiedOutbound performs a live SMTP verification prior to unlocking contact data. If a mailbox is invalid or catch-all, no credits are deducted.
