Exclaimer

Exclaimer gives you full control over your company's email signatures without needing to touch individual devices. Instead of relying on employees to update their own sign-offs, you can manage every signature from a central web-based dashboard. This ensures that every email sent from your organization—whether from a desktop, mobile, or tablet—remains professional, on-brand, and legally compliant.

You can easily integrate dynamic content like social media icons, promotional banners, and personalized headshots into your templates. The platform works silently in the background of Microsoft 365, Google Workspace, or Exchange, so your team doesn't have to change how they work. It is an ideal solution for marketing and IT teams at mid-market and enterprise companies who want to turn every everyday email into a high-volume marketing channel.

Shortwave

Shortwave is an AI-powered email client designed to transform your messy inbox into a structured workspace. It replaces the traditional list of emails with a focused view that automatically bundles related messages, such as newsletters and promotions, so you can handle them in bulk. You can snooze tasks for later, pin important conversations to the top, and use a built-in calendar to manage your schedule without leaving the app.

The platform integrates advanced AI to help you write better emails and find information instantly. You can ask the AI assistant to summarize long threads, draft replies in your unique voice, or search through your entire history using natural language. It works directly with your existing Gmail account, ensuring your data stays synced across all your devices while providing a much faster, more organized experience.
