What I learned running WhatsApp automation on IndiaMart leads for 3 months
I built a lead automation system for a wooden furniture manufacturer. They get around 50-60 leads a day from IndiaMart and used to handle them manually someone copying leads into a sheet, typing WhatsApp replies, assigning sales reps by hand.
The automation pulls leads, sends a WhatsApp reply in under 30 seconds, collects product and city and quantity through a WhatsApp interactive form, and assigns the lead to a rep based on location. It works. But three things broke my mental model of how this was supposed to go.
1. Meta silently dropped 50% of my messages in week one.
The API returned "sent" but the messages were flagged internally as "Meta chose not to deliver." No bounce, no error. Over time it settled at around 30%.
The reason isn't random. IndiaMart shares the same lead with 5-10 sellers, so the buyer gets hammered by multiple businesses within the hour. Recipients start ignoring or blocking, the sending number's quality rating drops, and Meta throttles you.
Big lesson: I used marketing templates (approved by Meta). Utility templates would have given better delivery since we're responding to a user-initiated inquiry. I'm switching.
2. The reply rate is humbling.
70% of leads get contacted successfully. Of those, about 5% reply. Sounds bad, but for furniture at 50-200 unit quantities, 2-3 replies a day is real B2B pipeline. The value isn't a magical reply rate, it's that the sales team only touches leads that actually responded, instead of burning hours on people who were never going to.
3. Hinglish replies are harder than I expected.
"Haan chahiye," "price kya hai bhai," "kal baat krte h", Roman-script Hindi mixed with English and typos. A plain GPT prompt handles the obvious ones but misses edge cases. Still iterating.
What I'd do differently: proper dashboard from day one (not Google Sheets), delivery-rate monitoring built in from the start, and warming up the WhatsApp number with low-volume sending for the first week.
Stack: n8n self-hosted, WhatsApp Cloud API (direct, not Twilio), OpenAI for parsing, Google Sheets, IndiaMart's lead API.
Curious what others running automation on Indian marketplace leads have seen. the English automation content online doesn't really cover this.
