About esigna
esigna is a web-based email signature generator that lets users design, save, and export signature PNGs for use in Gmail, Outlook, Apple Mail, Proton Mail, Thunderbird, and other clients that support image signatures. Users can choose from eight signature layouts, customize colors, fonts, and contact lines, and share signatures via hosted preview links. The product also offers optional AI-generated personalized bobblehead avatars created from an uploaded photo, using one-time credit packs. Signatures can be created and exported for free without purchasing avatar credits.
