I'm using .htm Signature in my outlook which looks good when view in PC/Laptop but if open same in phone or tablet it don't display as responsive means it don't become vertical layout rather it show same as PC version horizontal.
So looking for someone who can make it responsive quickly.
I've done this before for a client and should have no problem knocking it out for you! If you already have the file just forward it to me and I can make it responsive. Does it show correctly when viewed on a tablet as well?
