A signature generator that actually works in every email client.
Most email signature generators produce HTML that breaks in Outlook, gets clipped by Gmail, or shows broken images on mobile. Sigavo is built differently — every template uses table-based markup with inline styles, the same approach professional designers use for transactional emails.
Email-client safe HTML
Tables with inline styles — the only layout that renders consistently across Gmail web, Gmail mobile, Outlook desktop (Word engine), Outlook web, Apple Mail, ProtonMail, Yahoo, Zoho and any client that accepts HTML signatures.
Under Gmail's clipping limit
Gmail clips emails larger than 102 KB. Our signatures average 3 KB — no clipped messages, no "View entire message" link breaking your branding.
No tracking, no surprises
The free generator runs entirely in your browser. We never add tracking pixels, click trackers, or referral parameters to your signature. Your contacts see exactly what you typed.
Switch templates without losing data
All 15 templates share the same fields — Professional, Executive, Card, Hero, Modern, Studio, Corporate, Aurora, Elegant, Press, Nebula, Bold, Sales, Minimal, Compact. Switch any time without retyping anything.
Frequently asked questions
Is the email signature generator really free? +
Yes. You can build, preview, copy and download as many email signatures as you want — no payment, no signup. Sigavo Pro adds features like saving signatures, removing the small Sigavo branding, hosted images and click analytics, but the generator itself is free forever.
Do I need to create an account? +
No. The free generator works entirely in your browser. You only need an account if you want to save and edit signatures across devices.
Will my signature render correctly in Gmail and Outlook? +
Yes. Every Sigavo template uses table-based HTML with inline styles — the same battle-tested markup that professional designers use for transactional email. We test specifically against Gmail web, Gmail mobile, Outlook desktop (which uses the Word rendering engine), the new Outlook, Outlook on the web, and Apple Mail.
Can I add my photo and company logo? +
Yes. Paste any public HTTPS image URL into the Photo or Logo fields. For best results, use square images (256×256 or 512×512) and host them somewhere stable — your own website, an asset CDN, or Sigavo Pro hosted images.
Which template should I pick? +
Professional is the safest default — photo on the left, accent bar, clean info on the right. For senior roles try Executive (Georgia serif, hairline divider). For tech and SaaS try Card or Nebula (dark mode). For creative agencies try Studio. For sales and bookings try Sales (CTA-focused). Browse all 15 designs on the templates page.
Can I use Sigavo for my whole team? +
For now, build signatures one at a time — each team member can do this themselves in under a minute. Team management with shared brand defaults is part of the Pro roadmap.
