Back in 2017, I was experimenting with something that was pretty fun for the CSS we had at the time — building icons without using images. Using mainly CSS, :before, :after, borders, shadows and a bit of creativity, I managed to create a set of icons that didn't depend on external image files. The interesting part for email was simple: no images to load or block — the icons are always visible. You can still see that old experiment here: https://codepen.io/k0ko88/pen/PWLNBJ Fast forward to 2026. At my last job, I decided to apply some of that old knowledge to an email signature. And then I met Classic Outlook again. :D What looked like a simple signature quickly turned into dealing with Outlook's rendering limitations, different behaviour between email clients, px → pt conversions, table rendering and weird spacing issues. Along the way I found a few useful tricks — one of my favourites being that line-height: 0.5pt can practically zero out a line in Classic Outlook, which solved one of the most annoying spacing problems I had. Eventually, that little fight turned into a complete email signature generator: SimpleSignature https://nikolaisabev.eu/SimpleSignature/ It's not trying to be the prettiest or the most complicated signature generator out there. It's simple, effective and built around what I learned from actually fighting with email clients. It's completely free, there's no registration, and I don't store the data you enter. Feel free to use it. If you find a bug, have an idea, or think something could work better, leave a comment here or send me an email. Feedback is more than welcome. And if it saves you some time and you feel like supporting the work, there's a Buy Me a Coffee button. If you wish. :) That's it. Cheers, Nikolay
