'Hide' the wording "Discover our new print products!" from the heading of every message.
When I see a message from you in the inbox on my iPhone I see who it's from, e.g. "Steffy commented on Joshua Michael's timeline", but then I get two lines of advertising saying "Discover our new print products!"
This means that I have open the message to read what Steffy has said.
I think that it is possible for you to "hide" all of the opening text [inside some sort of picture frame?] so that the iPhone message preview shows the opening words of what Steffy has said. Then I can choose to see the whole message (with advertising etc) if I want to.
Thank you for considering this,
