Email Signature Rescue - Browser Extension

Email Signature Rescue - Browser Extension simplifies the process of installing HTML email signatures into popular webmail clients. It eliminates the need for manual code editing, allowing users to set up professional signatures in Gmail, Office 365, Outlook.com, Yahoo Mail, and AOL Mail without character limits. Whether you are a free user with your own HTML code or a paid member with access to advanced features, the extension provides a straightforward workflow: select your webmail provider, enter your signature key (for paid users) or paste your HTML code, and save. The extension is designed for users who need consistent, branded signatures across multiple accounts and webmail platforms.

Key Features

• Simple Installation: Instead of manually editing email client settings or inserting code into complex configuration pages, you just select your webmail client from the extension popup, enter your signature key (if you are a paid member) or your HTML signature code, and save. This process takes only a few clicks, making it accessible for non-technical users.
• Seamless Integration: The extension works with major webmail providers: Gmail, Outlook Office 365, Yahoo Mail, and AOL Mail. It automatically places the signature into the correct location within the compose window, so you don't have to worry about compatibility or formatting issues.
• Automatic Updates (Paid Feature): If you are a paid Email Signature Rescue member, any changes you make to your signature in your online ESR account are automatically pushed to the extension. This means your signature updates instantly in your webmail client without you having to reinstall or manually edit anything. This is especially useful for teams or businesses that need to update signatures across multiple users.
• Multiple Signature Support: You can set up and manage different signatures for different email accounts, even if they use the same webmail client (e.g., two different Gmail accounts) or different clients (e.g., one Gmail and one Outlook). This is useful for users who have separate personal and professional accounts, or who manage multiple brands.
• Custom HTML Signatures: If you have your own HTML code-whether created by a designer, generated by another tool, or written yourself-you can paste it directly into the extension via the Advanced Settings. This gives you full control over the design and content of your signature, without being locked into a template.
• Live Preview: Before you send an email, you can see exactly how your signature will appear in the compose window. This ensures that the signature looks correct-fonts, images, links, and layout-so you can catch any issues before your recipients see them.
• Free to Use with Custom HTML: The extension is completely free if you paste your own HTML code. You don't need a paid subscription to use the basic functionality. The paid service (ESR Dashboard) provides online tools to create, design, and manage signatures, with automatic updates pushed to the extension via an API.
• Ongoing Support and Updates: Email clients frequently change their underlying code, which can break signature installations. The development team actively monitors these changes and releases updates to maintain compatibility. The extension has been updated multiple times to fix issues such as signature duplication, missing signatures, and auto-update failures. If you encounter a problem, you can contact support, and they will work to resolve it.

The extension currently supports over 60 email clients, apps, and software across Windows, macOS, browsers, iOS, and Android. While the primary focus is on webmail, the team strives to maintain broad compatibility. Whether you are an individual user wanting a professional signature or a business needing centralized signature management, Email Signature Rescue provides a practical solution with both free and paid options.
