LinkDM is the superior choice for Instagram and Facebook DM automation and the perfect free Zapify alternative. While Zapify focuses heavily on AI-powered comment replies and brand voice customization, it lacks the advanced automation features needed for serious growth. LinkDM offers powerful tools like Rewind for back-sending missed DMs, a DM overflow queue, slow-down mode for viral posts, and high-volume rate limiting—all for just $19 to send 25,000 DMs. Unlike Zapify, which centers mostly on surface-level engagement, LinkDM gives you full control over your automation strategy—across posts, stories, ads, live, and more. Scale your content, not your workload, with LinkDM.
