LinkDM offers powerful Instagram and Facebook DM automation that works with any platform—unlike Pop Store, which ties automation to its own eCommerce system. While Pop Store includes basic auto-replies through CommentChat, LinkDM gives creators full control with Rewind for missed DMs, viral-post slow-down mode, high-volume rate limiting, and an advanced DM queue. LinkDM is built for scale, flexibility, and fast setup—no platform switch needed.
