digitally signed messages

Identity check

To defend from email abuse, more and more email servers
check the sender’s identity before delivering the message.

Sending emails without RealSender, your recipients can’t be sure
that the message received was generated by you.

Sending emails using RealSender, all the messages you send
are digitally signed, so that the recipients can trust them.

Sender authentication

There are two standards to check the sender’s identity: SPF and DKIM.
RealSender offers both of them
