Dear Customer
Chrome extension for WhatsApp Web

Dear Customer.
No.

Same business. Another number. Another offer you never asked for. Find promotional senders on WhatsApp Web, see the numbers each business has used, and choose who gets bounced.

What one click does

Opt out

WhatsApp's own stop-marketing setting, plus a STOP sent to the business. Two systems, one click.

Report

Reports the selected sender to WhatsApp with message context. WhatsApp decides what action to take.

Block

Stops messages from that number, including useful updates. Review the sender first.

Archive

Out of your chat list. Unarchive any time.

How it knows what is an ad

01
Message labels. Uses marketing, utility and authentication categories when WhatsApp makes them available.
02
Words and buttons. Looks for promotional language and calls to action. Transactional signals help distinguish order updates, OTPs and bills. These are clues, not a guarantee.
03
You, always. Nothing is acted on until you press Bounce. Review the conversation first. Untick or ignore businesses whose updates you still need; ignored senders can be restored.

Before you bounce

What about bookings, tickets and order updates?

Dear Customer sorts each number by everything it has sent you. A number that only sends orders, bookings or OTPs is left alone. A number that sends both offers and updates only gets WhatsApp's own marketing opt-out and, where the business offers one, a "stop promotions" button. It is never blocked or reported, and no typed STOP is sent to it, so your updates keep coming. Numbers that only send promotions get the full treatment.

Version 1.0.2 and earlier blocked every number of a ticked business. If you are on one of those, leave a business you still buy from unticked or choose Ignore; your copy updates on its own within a few hours of the new version going live.

Does this cost spammers money?

Dear Customer makes no promise about a business's marketing budget. It brings together opt-out requests, reporting, blocking and optional public reports of repeat spam. WhatsApp decides how to enforce reports; the Wall makes the pattern visible.

What it will not do

—
Upload private chats to Dear Customer. Analysis runs in your browser. Choosing Report can send message context to WhatsApp. Wall contributions contain business names and hashed sender numbers; sharing is optional.
—
Run an outreach campaign. Opt-out requests and STOP replies go to selected existing senders. STOP replies are capped and can be switched off.
—
Name a business on one person's say-so. The Wall needs 3 separate users on different networks before a business is listed, and only official WhatsApp business accounts can be added.
