This generator uses table-based layouts and inline CSS which are the most compatible approach for email clients, including older versions of Outlook. No external images or web fonts are used, so the signature displays reliably even when images are blocked.

What font size should I use for an email signature?

Most email signatures use 12–14px for body text. Your name is typically larger at 16–18px. On mobile devices, text smaller than 13px can be hard to read. This generator offers Small (12px body), Medium (14px body — recommended), and Large (16px body) presets.
