Why is MailSig free when others charge $5–12/month?
Signature generators love subscriptions: they inject a "Created with …" link into your signature, lock the good templates behind a paywall, or make you sign up just to copy your own signature. An email signature is a few lines of HTML — it does not need a monthly fee.
MailSig runs entirely in your browser. Nothing you type is sent anywhere, there is no account, and the signature you copy contains only your information. If we ever charge for anything (Pro), it will be a one-time purchase — never a subscription.
FAQ
How do I add a signature in Gmail?
Click Copy signature, then in Gmail go to Settings → See all settings → General → Signature, create a new signature, and paste. Set it as your default and save. Full steps are in the "How to install" section above.
Why does my photo not show?
Email clients can't read images from your computer — the image must live on the internet at a public URL (starting with https://). Upload your photo or logo somewhere (your website, an image host, or use your LinkedIn photo URL) and paste that link. If the image shows in the preview here but not in a received email, the host may be blocking email clients — try a different host.
Is MailSig really free?
Yes. Everything on this page is free and stays free. We may later sell a Pro tier (saved signatures, team templates, more designs) as a $9 one-time purchase — never a subscription. The free generator will not get worse to push you there.
Will MailSig add its own branding to my signature?
No. Never. Many "free" generators quietly append a "Created with X" link to your signature — that's their real business model. The HTML you copy from MailSig contains only what you typed. You can verify it yourself with the Copy HTML code button.
Why use tables instead of modern HTML?
Email clients render HTML like it's 2003. Outlook in particular ignores flexbox, grid, CSS classes, and most modern layout. Old-school tables with inline styles are the only layout method that renders consistently across Gmail, Outlook, and Apple Mail — so that's exactly what MailSig generates, even though it looks ancient under the hood.
Does my data leave my browser?
No. The whole tool is one HTML file running locally in your browser. There is no server, no database, no analytics, and no cookies. We literally couldn't see your details if we wanted to. Close the tab and it's gone.
