WhatsApp first

Why lead with WhatsApp in India?

In India, WhatsApp is where customers already are: half of all adults use it, and three in four of those aged 18–29. It is the second most-used platform for news after YouTube. In the US only 29% of adults use it, so WhatsApp-first suits markets like India, not everywhere. Meta itself stops delivering marketing messages to people who don’t engage, so more broadcasts are not better. No independent study yet compares sales by channel.

What to do

In India, make WhatsApp the easiest way to reach you, and answer there.
Keep broadcasts relevant and occasional: WhatsApp cuts off people who stop engaging.
In the US, use SMS or email for promotions; WhatsApp doesn’t deliver marketing templates to US numbers.

What the research says

Independent research
WhatsApp and Facebook dominate the social media landscape in middle-income nations
Pew Research Center, 2024
50% of all Indian adults use WhatsApp, against 39% for Facebook. Among Indians aged 18–29 the figure is 75%, and among those 50+ it is 17%. In the US only 29% of adults use WhatsApp.
What it means for you: In India, WhatsApp reaches more adults than any other platform, especially under-30s. In the US, don’t lead with it.
Keep in mind: Share of all adults, including people not online. Data from 2023; the UAE wasn’t surveyed.
Method and quote
2023 Global Attitudes Survey, face-to-face, 25 Feb–22 May 2023, 10,235 adults across eight countries including India. US data from NPORS 2023 (5,733 adults). Nationally representative.
“In all eight surveyed countries, at least half of adults use WhatsApp, with shares ranging from a low of 50% in India to a high of 90% in Brazil. In the United States, by comparison, only 29% of adults use WhatsApp." The piece adds: "in India, three-quarters of 18- to 29-year-olds use WhatsApp, compared with only 17% of those ages 50 and older.”

Digital News Report 2025: India
Reuters Institute, 2025
46% of India's (mainly English-speaking, online) sample use WhatsApp for news, second only to YouTube (55%). 53% name WhatsApp as the biggest misinformation threat.
What it means for you: WhatsApp is where Indian customers already spend their attention, but trust is low, so messages must clearly come from the business.
Keep in mind: Measures news use in a mainly English-speaking online sample, not business messaging.
Method and quote
Online survey, 2025. The report describes its India sample as "primarily English-speaking", so it is not representative of all Indians.
“…social media platforms such as YouTube (55%), WhatsApp (46%), Instagram (37%), and Facebook (36%) being predominantly used for this purpose amongst our primarily English-speaking survey sample." The report also says: "WhatsApp was cited by more than half of our Indian survey respondents (53%) as the channel that carried the biggest threat when it comes to false and misleading information…”

WhatsApp per-user marketing template limits
Meta, WhatsApp developer documentation
WhatsApp throttles marketing messages to people who are less likely to engage, based on their read rate and inbox activity. It does not deliver marketing templates to US numbers at all.
What it means for you: Sending more broadcasts backfires: WhatsApp itself stops delivering marketing to people who don’t engage. In the US, promote by SMS or email.
Keep in mind: Meta changes these rules often; check them before each campaign season.
Method and quote
Platform policy.
“WhatsApp may limit the number of marketing template messages a WhatsApp user receives from any business in a given period of time when they are less likely to be receptive and engage with those messages." The page also says: "WhatsApp does not currently deliver marketing template messages to WhatsApp users with United States phone numbers…”

Dynamically Managing a Profitable Email Marketing Program
Zhang, Kumar & Cosguner, JMR 2017
Message volume has a nonlinear effect. Sending 10 emails instead of the optimal 7 cost 16% of lifetime profit per customer, and sending 4 cost 32%.
What it means for you: There’s a sweet spot: both too many messages and too few cost money.
Keep in mind: Email at one retailer; the best frequency differs by business.
Method and quote
A US home-improvement retailer's email and purchase data, using a hidden Markov and copula model with counterfactuals.
“sending four (ten) emails instead of the optimal number of seven emails can cause the retailer to lose 32% (16%) of its lifetime profit per customer.”
