I'd recommend you Exclaimer. Very user-friendly tool. In my opinion, it's more suitable for email signature management than HubSpot. HubSpot provides email signature functionality as part of its CRM offering. While Exclaimer specializes in email signature management solutions specifically tailored for businesses and organizations. It allows users to centrally manage and control email signatures across the entire organization, ensuring consistency, compliance, and professionalism in all outgoing emails.
