Caspio requires that account administrators verify their email addresses to prove that the messages are indeed sent by their owners. Additionally, to ensure the best email deliverability, account owners can choose to verify their domains to sign the messages with DKIM.

DKIM (DomainKeys Identified Mail) is an email authentication standard designed to ensure that an email message that claims to have come from a particular domain was indeed sent and authorized by the owner of that domain. This is possible thanks to an encrypted, digital DKIM signature added to an email message to verify if its parts have not been altered during the transfer.

If you want to enjoy the best deliverability and security standards without editing any advanced email settings, you can use a pre-verified default email address <> hosted on the Caspio-owned domain.

Note: Due to the deprecation of unverified email addresses, we strongly encourage account administrators to verify their email addresses and domains.
