About Siglio
Who we are
Siglio was built out of a simple frustration — creating a professional email signature should not take hours, require a designer, or cost a fortune. Every email you send is a chance to make a great impression, and your signature is part of that.
We built Siglio to make professional email signatures accessible to everyone — from the solo freelancer who wants to look polished, to the HR manager who needs to roll out consistent signatures across an entire team in minutes.
Siglio is built by a small team focused on creating practical, well-designed tools for professionals and businesses.
What we do
Siglio is a professional email signature generator. You fill in your details, choose your template, customise your colours, and copy your finished signature directly into Gmail, Outlook, Apple Mail, or any other email client — in minutes, not hours.
For teams, Siglio makes it easy to generate individual signatures for every team member and share them via a unique link. Your colleague opens the link, sees their ready-made signature, and copies it in one click. No design skills required. No back-and-forth.
Our values
Simplicity first. Every decision we make is guided by making things easier for you. If a feature makes the app more complicated without making it meaningfully better, we leave it out.
Honest pricing. Your first signature is free. If you want to remove our watermark, you pay a small one-time fee — no subscriptions, no monthly bills, no surprise charges.
Privacy by design. We collect only what we need to run the service. We do not sell your data. We do not show you ads. Your signature content belongs to you.
Built for real people. We design for the HR manager who needs to onboard 20 new staff, the consultant who sends 50 emails a day, and the small business owner who wants to look professional without hiring an agency.
