A professional email signature in two minutes, paid once
Sigsprig builds your signature from nested tables and inline styles only, the way email designers do, and checks every template as you type: no style blocks, no flexbox, image widths and alt text, and the size against Gmail's 10,000-character limit. Copy it as a formatted signature, copy the HTML, or download a .htm file, then follow the step-by-step guide for Gmail, Outlook, Apple Mail, iPhone, Yahoo or Thunderbird.

FAQ
Why not WiseStamp?
WiseStamp is a managed signature service billed monthly (Pro+ $9/month on annual billing, checked 2 Oct 2026), with central management and analytics. If you only need a signature that looks right everywhere, Sigsprig Pro is $15 once.
Why do my images not show?
Email apps only show images at a public URL. Use the image address from your website or company site; embedded images are often hidden by Gmail and Outlook on the web.
Is my data private?
Yes. Sigsprig runs in your browser; nothing is uploaded and there is no account.
Can I cancel?
There is nothing to cancel: Pro and Team are one-time payments.
