A self-hosted PHP web application for building, managing, and exporting professional HTML email signatures — 15 templates, brand customization, photo & logo upload, AJAX live preview, and multi-user support.
Siggy is a self-hosted web application that enables organizations and individuals to create, manage, and distribute professional HTML email signatures. Users fill in their contact details once, select from fifteen professionally designed templates, customize brand colours and typography, upload a profile photo and company logo, and receive ready-to-use HTML that works in Gmail, Outlook, Apple Mail, and all major email clients.
Multiple signatures per account allow users to maintain separate identities for different roles, contexts, or campaigns. The application is built on a zero-dependency PHP stack with a MySQL backend, making it straightforward to deploy on any standard LAMP or LEMP server without container infrastructure or external package managers.
