Deliverability
Renders everywhere. Every time.
A signature is only as good as the client that renders it. We test against 40+ inbox/device combinations.
Email-safe HTML
Nested tables, inline CSS, no external JS. Same markup used by Fortune 500 email teams.
Mobile-perfect
Responsive layouts collapse gracefully on iOS and Android — no zoom, no overflow.
Dark mode ready
Foreground colors, logos, and dividers auto-invert in Apple Mail, Outlook and Gmail dark modes.
40+ client tests
Every template rendered against Gmail, Outlook 2016/365, Apple Mail, Yahoo, and mobile clients.
Anti-clipping
Signature markup stays under Gmail's 102KB clipping threshold — no 'view entire message' footer.
Fallback images
Every icon and logo ships with PNG fallbacks for clients that block SVG or web fonts.
