What is SigStudio?

SigStudio is an advanced email signature management platform built by Email Signature Rescue, a team with over a decade of experience in creating, managing and deploying HTML email signatures with software.

SigStudio lets you easily create, edit, and manage professional HTML email signatures for your entire team, all in one place.

With SigStudio, you can import users, manage company brands and workspaces, upload images, customize templates, and send out ready-to-install signatures in minutes, not days.

At its core, SigStudio gives marketing, brand, and IT teams full control over how their organization presents itself in every email. Admins can update colours, fonts, logos, banners, and social icons from a central dashboard, with every change reflected instantly in a live team previewer. The platform ensures that professionally coded templates stay perfectly structured regardless of how many edits are made.

Visual Editor & HTML Editor

SigStudio offers a drag-and-drop Visual Editor that lets non-technical admins manage signature design with ease — toggling elements on or off, updating content across the entire team, adding or swapping banners, sorting social icons, and customizing individual users when needed. For tech-savvy teams requiring pixel-level precision, a full HTML editor is also available, complete with syntax highlighting, live preview rendering, and dynamic merge fields (such as name, title, and phone number) that auto-populate per user at deploy time.

Creator Studio

Included on all plans, the Creator Studio is a built-in design toolkit that provides 500+ brand icons (including contact icons for phone, fax, email, and more), personalized promotional banner creation with 20+ photo-based templates, decorative dividers and flourishes in brand colours, and bulk photo upload tools. SigStudio automatically crops, resizes, and optimizes team photos for crisp, retina-ready signatures, and auto-matches photos to users based on filenames.

Team & Brand Management

SigStudio supports unlimited Workspaces, allowing organizations to organize signatures by department, brand, region, or client. Admins can build signatures from team data and lock designs with brand templates, ensuring layouts and fonts stay on-brand at all times. Workspaces, groups, and roles are available for organizations of any size, and updates can be rolled out to hundreds of users in seconds.

Deployment & Compatibility

SigStudio automatically installs and updates signatures in Gmail, New Outlook, and Apple Mail. For all other email clients, apps, and CRMs, guided setup is available. The platform is compatible with 60+ email clients, apps, and CRMs. Updates can be pushed instantly via API, hosted HTML, or guided manual install.

Review & Export

Before publishing, admins can review every team member's signature. Signatures can be previewed, shared via a public link, or exported as an HTML download.

SigStudio is positioned as a replacement for fragmented tools and manual processes, enabling brand directors and IT teams to roll out new branding or signature updates in under an hour. It offers a 30-day trial for just $1, with no commitment required.
