Frequently Asked Questions
Will this work in all email clients?
The generated HTML is tested for Gmail (web + mobile), Outlook 2016/2019/2021/365 on Windows, Apple Mail on macOS and iOS, and mobile Gmail. Inline CSS is used throughout to maximise compatibility — email clients notoriously strip external stylesheets.
Can I use a hosted image for my logo?
Yes. Enter a full HTTPS image URL in the Logo URL field. The image must be publicly accessible — local file paths will not work in email clients. Cloudinary, ImgBB, and your own CDN all work well.
How do I add the signature to Gmail?
Copy the HTML output, open Gmail Settings → See all settings → Signatures → Create new, click the source code icon in the editor toolbar, paste the HTML, then save.
How do I add the signature to Outlook?
Copy the HTML, open a new email in Outlook, go to Insert → Signature → Signatures → New, name it, then paste into the rich-text editor. For best results in Outlook, download the .htm file and import it.
Is my contact information stored anywhere?
No. All data you enter (name, email, phone, company) is processed entirely in your browser. Nothing is sent to any server. Refreshing the page will clear your inputs.
