What is a follow gate?

1. Someone comments your keyword, say GUIDE. They get a public reply and a plain-text DM asking them to reply.
2. They reply. Now the tool can read their profile, because Meta allows that only after a person has messaged the account, tapped an ice breaker or used its persistent menu.
3. The tool asks Meta whether they follow the business. The answer comes back as yes or no, in a profile field called is_user_follow_business.
4. If yes, the link goes out. If no, they’re asked to follow, usually with an “I followed” button that runs the check again when tapped.

The order is forced by Meta’s rules, not by the tool. A comment alone doesn’t count as consent: if someone has commented but never messaged the business, Meta’s API refuses the profile request with an error saying user consent is required. That’s why every follow gate starts with a reply.

• Instagram only. Messenger doesn’t tell tools whether someone follows a Facebook Page, so there’s no follow gate for Pages.
• One moment in time. The check sees whether someone follows at the moment it runs. If they unfollow tomorrow, nothing changes and the link they received keeps working.
• Inside the 24-hour window. Every message in the flow, including a reminder to someone who stopped at the follow step, has to go out within 24 hours of their last message.
• Blocked accounts are out of reach. If someone has blocked your business, a tool can’t read their profile at all.

In DMFast the option is called “Only send to followers”. The follow check runs when the person replies or taps I followed, and an optional reminder can nudge anyone who stops halfway.

A gate turns interest into followers, but each extra step loses some people. Someone who came for a recipe has to leave the chat, find the Follow button, come back and tap again. Use it where a follow is worth more to you than the extra people you’d otherwise reach.

• Good fits: a free guide that leads into a series, templates that only make sense alongside your future posts, and giveaways where following is already an entry rule.
• Poor fits: price lists, bookings, order updates and support. People asking those are customers or close to it, and a gate between them and an answer can cost the sale.
• Say it up front. “Follow and comment GUIDE” in the caption avoids a surprise in the DM, where an unexpected condition can feel like a bait-and-switch.
• Measure both sides. Compare followers gained with links delivered before and after you turn the gate on.

Tip: Keep the follow request to one line: “Follow us, then tap I followed and the guide is yours.” Every extra sentence is a chance for someone to give up.
