Design the email signature your brand deserves, then turn every teammate's email into an ad channel you already own.
Wren is an email signature management platform that enables teams to create and deploy professionally designed, on-brand email signatures quickly and without IT involvement. It provides a real-time signature preview and central control over banner campaigns, allowing marketers to update promotional banners across all team emails with a single click. Wren works seamlessly with popular email clients like Gmail, Outlook, and Apple Mail, as it generates table-based HTML signatures with inline styles. A key differentiator is its zero-access design: Wren never connects to your mail server, requiring no admin console, OAuth, or SMTP relay. Instead, signatures are installed by each teammate via a simple copy-paste link. The platform offers a free builder for individual use, and paid plans for teams with a flat rate pricing model. With EU-hosted infrastructure and a commitment to GDPR, Wren ensures data privacy and security. AiDOOS enhances deployment by offering automated onboarding, centralized management, and integration with existing workflows, accelerating the rollout of consistent email signatures across organizations.
