synkCheck the records behind your email.
Look up your domain’s public mail records before a move, or when something needs attention. This checks DNS, not private messages.
Public DNS records only. No signup, mailbox access or DNS changes. A DKIM selector identifies which public key to look up; ask your current provider if you don't know it.
Present does not mean fully verified.
A record may exist without authorising the right provider. This tool checks presence and basic syntax; it does not send a test email, verify a message signature, or guarantee delivery.
