Esigna turns email signatures into AI bobbleheads

A new tool called esigna is pitching a simple idea: most email signatures are forgettable, so make them stand out.

The app lets users build email signatures for Gmail, Outlook, Apple Mail, Proton Mail, Thunderbird, and other clients that support image-based signatures. Its hook is an optional AI bobblehead avatar generated from an uploaded photo, then placed into one of eight signature layouts. Users can also skip the avatar entirely and create a more standard professional signature.

The core editor is free. According to the site, users can design, save, and export PNG signatures at $0, with unlimited saved signatures, a live editor, PNG export, and share links with previews. No credit card is required to get started.

Avatar generation is where pricing comes in. Esigna sells one-time credit packs that never expire:

• Standard: 25 credits for $9.99
• Plus: 60 credits for $19.99
• Starter: 10 credits, available in the app after signup

A medium-quality avatar costs 1 credit, while high-quality costs 2 credits.

The workflow is straightforward: upload a photo, generate a bobblehead, choose a layout, then adjust colors, fonts, and contact lines. Finished signatures can be exported as a crisp PNG or shared via a hosted link.

The site also positions itself against more traditional tools. For users who want a plain corporate look with no avatar, it points to WiseStamp, HubSpot’s generator, and Newoldstamp as better fits for that style.

For setup, esigna says exported PNGs can be pasted or uploaded directly into signature settings. It specifically lists Gmail and both desktop and web versions of Outlook as supported destinations.
