FAQ

What happens if I don’t verify my sender email?

Unverified emails are more likely to be blocked, flagged as spam, or prevented from sending.

Can I verify multiple sender emails?

Yes. Each sender email must be verified individually.

Can someone else use my email address without verification?

No. Verification prevents unauthorized use of email addresses.

What if I never receive the verification email?

Check spam folders first. If missing, resend the verification email and confirm the address is correct.

Verification improves deliverability but does not guarantee inbox placement. Domain reputation and engagement still matter.
