Email Signature Magic is an email signature management platform for solo professionals and organizations, from small teams to enterprise. It helps users create polished, accurate signatures while giving organizations centralized control over branding and compliance details. Administrators set logos, colors, fonts, and compliance fields once; those settings cascade through organization, office, team, and member levels, with optional overrides for specific groups.

Individuals can connect a Gmail account, choose a professionally designed layout, and add their title and headshot. Organizations can invite members to connect their accounts, then manage new hires, role changes, and brand updates from one place. Changes to templates and shared details update automatically across connected inboxes. The platform offers ten layouts, including classic, minimalist, photo-based, and promotional designs, as well as tools for creating consistent signatures.

Email Signature Magic supports Gmail and Google Workspace today. Microsoft 365 and Outlook support is planned. Its signature designs use compressed images, alt text, full HTTPS links, and table-based HTML to support email compatibility and deliverability.
