The second order is the whole battle
The gap between that first purchase and the second one is exactly where the majority of Indian D2C brands quietly lose the customer for good, often without ever realising it has happened. Someone who buys twice is dramatically more likely to buy a third time. Someone who buys once and then hears nothing at all for two whole months is simply gone, and you will end up paying full acquisition cost all over again just to reach the very same person a second time.
So calculate your replenishment window per product. A 100ml serum used daily lasts roughly two months. A protein tub, about a month. Coffee, three weeks. Then set your reminder to land shortly before it runs out, not on a generic thirty-day schedule that suits your reporting calendar rather than the customer.
For non-consumables, the second purchase is a different product. Sequence it. Someone who bought a cleanser gets the moisturiser, not the same cleanser again.
What to actually build
WhatsApp flows first, because in India open rates make everything else secondary. Order confirmation, dispatch, delivery, then a usage tip a week later, then the replenishment nudge. Keep them short and useful. A message that only sells gets you blocked, and a block is permanent.
Subscriptions, where the product genuinely repeats. Even fairly light adoption of subscriptions completely transforms your unit economics over time, because the modest discount you hand over each cycle stays smaller than the full acquisition cost you manage to avoid paying.
A loyalty mechanic that rewards the next order, rather than accumulating points nobody redeems. Simple beats clever here.
And make the reorder itself trivial. A one-tap reorder link in the WhatsApp message that lands the customer in a prefilled cart. Every extra step costs you orders from people who had already decided to buy.
The uncomfortable part
If repeat rate is still poor after you have fixed all of that, the product or the experience is the problem. Delivery took nine days. The shade did not match the photograph. The packaging leaked. Returns were painful. Nobody complains about any of it, they simply do not come back a second time, and no amount of clever retention marketing will ever fix a product that people quietly did not enjoy using.
Call twenty customers who bought once and never returned. Not a survey. Actual calls. It is the least comfortable hour of your month, and it is usually the most useful one too. Then track your repeat rate by cohort month rather than in aggregate, so you can actually see whether the changes you made back in March improved the specific customers you happened to acquire during March.

Win the second order and the rest gets much easier, so build everything around the window when the first product runs out. Work out how long your product lasts. Then reach the customer a little before that, with a reason to reorder. Most brands message everyone at the same interval regardless of product, which misses the moment entirely.
It depends entirely on category. Consumables should expect far higher rates than furniture or luggage. Compare against your own trend by cohort, rather than against a benchmark from a different category, which will only mislead you.
WhatsApp for time-sensitive nudges and reorders, email for longer content and detailed offers. Email costs less per send and works well for the customers who do read it, so run both rather than choosing one.
