Why authentication matters

Switch each record on and watch what happens to a typical order email. We set all of this up for you on every plan.

SPF record

Lists the servers allowed to send for your domain.

DKIM signing

Signs each message so receivers can verify it.

DMARC policy

Tells inboxes what to do with mail that fails.

TLS transport

Encrypts mail between your app and the relay.
