Good to know

• Per-account. If you have several mailboxes, pick the right account at the top of the Signatures pane and repeat the paste.
• Using classic Outlook? The desktop Outlook with File → Options menus is the classic version — follow the classic Outlook guide instead (it can install a pixel-perfect .htm file).
• Spacing looks doubled? That's an Outlook rendering quirk with non-optimized HTML — OnceSig templates avoid it by design. Details in the spacing fix.
