Launching a product drop with Instagram and WhatsApp

Two weeks out: tease and collect

1. Post a teaser reel with a keyword: "Comment DROP to get first access".
2. The DM confirms they are on the list and asks for their WhatsApp opt-in or email.
3. Repeat with two or three more teasers: materials, behind the scenes, price hint.
4. Count sign-ups daily; they tell you how much stock to prepare.

Why WhatsApp for launch day

Instagram only lets you message someone freely within 24 hours of their last message, so a DM sent on launch day may not reach the people who commented two weeks ago. A WhatsApp opt-in lets you send the launch message as a marketing template to everyone who asked, at a time you choose.

The day before

• Get your launch template approved: product, price, link, time of launch.
• Check your messaging limit covers your list, and stagger sends if not.
• Prepare your inbox team for questions about sizes, COD and delivery.
• Load stock and test checkout on a phone.

Launch hour

1. Send the WhatsApp launch message to the waitlist first, a set time before going public.
2. Post the launch reel with a keyword that sends the product link in the DM.
3. Pin a comment with the keyword so late arrivals know what to type.
4. Watch stock and replies; pause the broadcast if a size sells out.

After the drop

• Send order confirmations and shipping updates to every buyer.
• Confirm COD orders before dispatch; drop-day impulse orders are more likely to be refused.
• Offer a restock waitlist for sold-out items, by keyword.
• Review: sign-ups, launch-message clicks, orders, and how fast stock went.

Costs to plan

Each launch message to an Indian number is a marketing message at ₹0.8631 from 1 October 2026. A waitlist of 10,000 costs about ₹8,631 in Meta's charges. Instagram DMs do not carry a Meta per-message charge, but some tools cap DMs per month or bill by contact, which matters on launch day.

Teasers that build the list

• A close-up of the material or detail, with the keyword.
• Behind the scenes of making or packing it.
• A price hint, or the number of pieces available.
• A countdown story with a question sticker.

Restock waitlists

Sold-out sizes are a second launch waiting to happen. Add a keyword such as RESTOCK to the launch reel and send people who comment it a DM that collects their WhatsApp opt-in for that product. When stock lands, message only that list.

Common launch mistakes

• Launching publicly before the waitlist gets its message.
• A comment keyword nobody can spell.
• No plan for sold-out sizes.
• Templates submitted the night before and still in review at launch.
