You’ve seen the move a thousand times: “Comment PODCAST and I’ll send you the episode.” A minute later the commenter has a DM with the link. Nobody on the creator’s team typed it. That’s Manychat.
It watches your comments, story replies, and DMs, with Instagram as its strongest channel and TikTok, Facebook Messenger, and WhatsApp also supported. When someone uses a keyword, it sends them whatever you set up: a link to the full episode, a free checklist, a newsletter signup, a discount code from a sponsor. It’s an official Meta partner, which matters, because unofficial DM bots are how accounts get restricted.
Manychat bills on active contacts, meaning the people you actually interacted with that month, not the size of your list.
If you go over your limit, automations keep running and you pay a small fee for each extra contact. You can cap overages so a viral post doesn’t surprise you. Essential and Pro have a 14-day free trial, and the Free plan needs no card.
The free plan used to allow 1,000 contacts; it now allows 25 active ones a month. One reel with a few hundred “send it” comments blows straight through that, so the free plan is for testing a flow, not running one. The point to upgrade is the first post you expect to do well.
Instagram and TikTok also change their messaging rules a few times a year, and flows sometimes break when they do. After any big platform update, comment your own keyword from a second account and check the DM still arrives.
Creators on Instagram, TikTok, or Facebook with a regular call to action: podcasters pushing full episodes, educators handing out free guides, anyone growing a newsletter, and creators who share sponsor codes or product links. If your audience lives mostly on YouTube, where you can’t automate comment replies like this, skip it for now.
The standard tool for the “comment a word” playbook, and the cheapest way to turn engagement into clicks and subscribers. Test a flow on Free, then move to Essential before the post you actually want to perform.
