I received an email today in my outlook from an agency that we deal with and I noticed that in my inbox reading panel it had the from name and then below the from name it has some text which is different to the subject line saying "Sorry we missed you but dont miss out on the content" and the subject line says Watch Digital journeys: Connected Live!. Interesting enough that inbox text isn't referenced anywhere in the body of the email either.

I think it would be a great product enhancement to have as part of the email marketing module.

I have attached a screenshot for reference.
