RobinReach's Auto DM watches the comments on your Facebook Page and Instagram posts. When a comment contains one of your trigger words (up to 25 per automation, with single words matched loosely so "guide" also catches "guides"), the commenter gets a private message from you, and optionally a public reply under their comment so everyone else sees the word works. Each person gets the DM once per automation. On Facebook it fires on any Page post, including posts you never scheduled through RobinReach.
The difference from everything else here is what surrounds it. The same account schedules to 13 networks, writes captions and images with AI, repurposes posts between platforms, keeps a comment inbox for Facebook, Instagram, LinkedIn and Threads, and lets Claude or ChatGPT run the calendar over MCP. There is no per-contact meter anywhere in the product: you pay for a plan, and the plan includes a number of automations.
Pros
- No Active Contact or DM cap. A viral post costs the same as a quiet one
- Facebook Pages and Instagram, with an optional public reply on the comment
- Included in the plan you would buy for scheduling anyway, from $9 a month
Cons
- Single-message DMs only: no branching flows, follow gates, email capture or AI conversations
- No WhatsApp, TikTok, Telegram or SMS messaging
- Not on the free plan, and the number of automations is capped per plan (3, 10, 30 or 100)
Bottom line: If a comment-to-DM trigger is the reason you pay for ManyChat, RobinReach does that job on Facebook and Instagram with no contact math, and replaces your scheduler in the same move.
