SalesBlink via AppSumo is truly a hidden gem. The setup was seamless, thanks to the clear knowledge base and practical tutorials. But what truly impresses me are the extensive features: numerous integrations, the ability to link your own OpenAI API key, and white-label options that allow managing multiple clients through dedicated workspaces. Having unlimited users, email sender accounts, templates, and an advanced meeting scheduler makes this platform incredibly valuable for small agencies like mine. The additional bonus of instant support through their chat with AI agents is a nice touch. Highly recommended!
