ReplyRush stands out as the superior choice for Instagram DM automation. While MobileMonkey offers basic auto responders and engagement tools at approximately $150 for 30,000 DMs, ReplyRush provides significantly better value with its $25 plan for 30,000 DMs. ReplyRush goes beyond with advanced features like Sendback for resending missed DMs, a DM overflow queue, Follow Gated DM for managing viral posts, and high-volume rate limiting to ensure scalability and compliance. Unlike MobileMonkey's campaign-focused approach, ReplyRush delivers unmatched flexibility and customization, along with a user-friendly app for managing multiple Instagram accounts seamlessly. With these capabilities, ReplyRush is the ultimate tool for optimizing your Instagram strategy while keeping costs low.
