Why Do Some Subscribers See "On Behalf of" in My Emails?
We have been using a form of email authentication referred to as Sender ID for for quite some time. This form of authentication results in much higher levels of deliverability, as this is a standard form of authentication.
For certain email clients, including some versions of Outlook, when an email is authenticated, subscribers may be notified of this authentication.
After they open the email, in the "From" line where the sender's address appears, they may see something that looks like the following:
Does This Appear to Every Subscriber?
This special message will only appear to a minority of subscribers using only a select number email applications, including certain versions of Outlook.
How Can I Disable It?
This message can not be disabled or avoided, since it is up to the email application how the message appears.
