htmlsig

htmlsig is a SaaS platform for creating, managing, and deploying HTML email signatures without requiring coding skills. It solves the problem of maintaining consistent, professional branding across an organization's email communications, particularly for teams that need to scale signature deployment efficiently.

The platform offers a drag-and-drop signature editor with over 40 customization options, including custom fonts, colors, layouts, and social media icons. Key capabilities include a central dashboard for managing all team signatures, click analytics to track link and banner performance, signature duplication for scaling, and shareable signature generators that let team members build their own branded signatures from a set template. Signatures are built with clean HTML that works across major email clients such as Gmail, Outlook, Apple Mail, Yahoo Mail, and Thunderbird.

htmlsig is designed for individuals and teams of all sizes, from freelancers to large organizations. It is offered in four paid plans—Starter, Plus, Team, and Scale—that are seat-based, with each plan including a set number of signatures and generators. Enterprise plans with custom pricing are available for larger needs. There is no free plan.
