thank you for reaching out to us and welcome back on Connect.
Unfortunately it is strictly forbidden to use any official logo, font, imagery as stated in the program rules. As per the rules for proper usage of the Google trademark: “Don’t display a Google Brand Feature in any manner that implies a relationship or affiliation with, sponsorship, or endorsement by Google, or that can be reasonably interpreted to suggest editorial content has been authored by, or represents the views or opinions of Google or Google personnel (this includes listing Google or the Google Logo to indicate partnership, affiliation, or sponsorship).”
However you can create any custom signature you would like by creating any custom graphic, or use the “powered by us” user logo which you can find here.
Oh really? Even if the E-Mail-Account is from google mail itself?
So just in case i could use the Logo you send me and customize it with my actual level…as an example?
