Made a short video on this today, quick breakdown here.
ManyChat charges per contact. 2500 contacts is 29 dollars a month and it climbs from there. My biggest keyword automation in GHL has over 115.000 contacts enrolled. That would have been thousands on ManyChat, on GHL it is just a normal workflow.
The exact build:
1. Trigger: Instagram Comment on Post, contains phrase = your keyword (add all casing variants)
2. Instagram DM: "are you following? reply yes for the link"
3. Wait for contact reply
4. Condition: replied message contains "es"
5. Yes branch: DM the link, wait a few min, one follow up DM
6. None branch: one nudge DM, wait, same condition again, then End
One workflow per keyword. Connect your IG under Integrations first.
Full step by step is in the GoHighLevel Masterclass in the classroom (around 3:27). Video is attached below if you want to watch it too.
