Repeat customer rate: the formula, and how to read yours
One number that tells you whether people come back. How to work it out from your bills.
Repeat customer rate is the share of your customers who visited more than once in a period. Count customers with two or more visits, divide by everyone who visited, and multiply by 100. Track it month by month: the direction it moves matters more than any single number.Read more Essay · 1 minThe Reten LetterIssue 05 ·Meta’s Business AI answers chats. Who brings back the people who stopped?
AI on WhatsApp helps the customers who message you. The ones who went quiet need something else.
In May 2026 Meta brought Business AI on WhatsApp to small businesses in India: it replies to customer questions in the chat. That helps people already talking to you. It can’t notice the customer who simply stopped coming, because they never message. Finding them still takes your bills, their usual rhythm and a message at the right time.Read more Essay · 1 minThe Reten LetterIssue 03 ·The second visit is the one that counts
Why the jump from one visit to two deserves more care than any loyalty card.
A first visit says someone was curious. A second visit says something worked. For most local businesses, the gap between visit one and visit two is where a thoughtful, well-timed follow-up does its most useful work.Read more Essay · 1 minThe Reten LetterIssue 01 ·The quiet signal hiding between two visits
Why a changing visit gap can be more useful than a one-off low bill.
The gap between two visits, compared with that customer’s usual gap, is often an earlier warning than a single low bill. Treat a widening gap as a reason to look closer, and keep the reason visible to the owner.Read more Essay · 1 minThe Reten LetterIssue 02 ·Attributed revenue isn’t the whole story
A clear way to review a win-back campaign without overstating its impact.
To judge a win-back campaign honestly, define a return before you send, subtract messaging and offer costs, and compare with a holdout group that got no message. Attributed revenue is a signal, not proof of extra profit.Read more Essay · 1 minNews
What’s changing, and what it means for you.
WhatsApp replies may now cost money: what changed on 1 October 2026
Meta’s own pages disagree. Here’s what we know, what’s still unclear, and what to do this month.
From 1 October 2026, Meta’s WhatsApp Business FAQ says replies to customers are charged after the first 1,000 a month for each business number. Its developer pricing page, checked on 10 October 2026, still says those replies are free. Until the two agree, plan as if replies past 1,000 cost a little, and switch your WhatsApp billing to rupees before 31 December 2026.Read more News · 1 minThe Reten LetterIssue 02 ·Your customer list and India’s new data protection rules
The DPDP Rules roll out in stages. What they mean for the phone numbers you collect at the counter.
India notified the Digital Personal Data Protection Rules in November 2025, and they phase in over 18 months. Most duties for businesses apply from around May 2027. If you collect customer phone numbers, start now: say clearly why you’re asking, keep a record of who said yes, and make it easy to say no.Read more News · 1 minThe Reten LetterIssue 03 ·WhatsApp usernames are coming. Will you still have customers’ numbers?
What Meta has changed so far, and why the phone number on your bill still matters.
WhatsApp is bringing in usernames during 2026, so some people may chat with businesses without sharing a phone number. Meta added a new customer ID to its business data from April 2026 and lets businesses reserve usernames from 29 June 2026. For now Meta still recommends messaging by phone number, so keep collecting numbers at billing.Read more News · 1 minYOUR NEXT CHAPTER
