Why must email signatures use table-based HTML?
Tables are the most reliable way to maintain alignment across all email clients. CSS and divs work in modern clients (Gmail, Outlook) but fail in older ones or mobile apps. Tables with inline CSS are universally supported — it's why they're still the standard for email.
Will my email signature look the same in all clients?
Not perfectly, but very close. Gmail, Outlook, Apple Mail, and most mobile clients render table-based HTML consistently. The differences are usually minor (font rendering, spacing). Avoid JavaScript, CSS3, and external stylesheets — stick to inline CSS on HTML tables.
How do I add my HTML signature in Gmail / Outlook?
Gmail: Settings → Forwarding and POP/IMAP → Signature → Switch to HTML mode → Paste code. Outlook Web: Settings → Mail → Compose and reply → Signature → Create new → Paste HTML (may require inspection). Outlook Desktop: File → Options → Mail → Signatures.
Should I include an image in my email signature?
Yes, but keep it small. A 150×150px logo or headshot loads fast and looks professional. Avoid large banner images — they bloat email size and annoy recipients on slow connections. Always include descriptive alt text for accessibility and fallback display.

Why We Built This Tool
Email signatures get stripped, corrupted, or rewritten by clients that don't support HTML. DIV-based layouts and CSS fail in older clients and mobile apps. Table-based HTML signatures with inline CSS ensure consistency across Gmail, Outlook, Apple Mail, and mobile — a professional signature requires understanding email client compatibility.
What Goes Wrong Without This
DIV-based and CSS-heavy signatures render perfectly in modern clients but misalign in older ones and mobile apps. Links become raw text, images disappear, and spacing collapses. Table-based signatures with inline CSS are the universal standard for email because they work everywhere.
