Want to save your perfectly created Signature as a Signature Block? No more copy-pasting HTML into an empty Signature Block.
Simply navigate to your list of Signature Blocks, hover over your chosen block and click the blue Copy HTML to Signature Block icon. Your Signature HTML will be copied into a new Signature Block ensuring identical formatting and design. Your new Signature Block will not be automatically added to any Signatures.
You can then freely edit your new Signature Block in visual or HTML editing mode, then apply it to your Signature(s).
