To find clients in Telegram and WhatsApp groups, join a few groups where your buyers talk to each other, answer questions for two weeks without selling, and reply to the people who ask for what you offer. Never send a private message to a stranger from the member list. Both apps treat that as the main sign of spam, and Telegram's own spam FAQ names contacting people who did not contact you first as a major cause of reports. Below: which groups to join, what each app's own rules say, a daily routine, the wording that turns a question into a conversation, and what gets you muted.
Which groups have buyers in them
Groups where buyers talk to buyers beat groups where sellers talk to sellers. A Telegram group of 4,000 marketing freelancers has 4,000 competitors. A WhatsApp group for owners of independent gyms in one city has the people who would hire you. The same goes for local trades, restaurant owners, property managers, online store sellers, clinic managers, import and export traders, and parents' groups if you sell to families.
Look for three signs before you commit time. People ask for recommendations ("anyone know a good accountant for an Etsy shop?"). The rules are posted and enforced. And the last ten messages are from at least five different people, not one admin posting links.
How to get in
Telegram has public groups and channels that anyone can find by name and join, plus private groups that need an invite link. WhatsApp groups are joined through an invite link from a member or admin, so on WhatsApp you start by asking people you already know which groups they are in. At a meeting of your buyer's trade association, in a customer's email signature, in a newsletter: those are where invite links usually come from. Do not buy lists of group links. Groups assembled that way tend to be full of promotion, and the people in them are used to ignoring it.
What each app's own rules say
Rules decide how long your account lasts, so read them once. All of this is from the apps' own pages as of November 2026.
| App | What the rules say | What it means for you |
|---|---|---|
| WhatsApp Terms of Service | Lists "sending illegal or impermissible communications such as bulk messaging, auto-messaging, auto-dialing" among prohibited uses, and bars non-personal use unless WhatsApp has authorized it | Do not use bulk tools or scripts on WhatsApp, and read its business policy before you run any business messaging |
| WhatsApp Business Messaging Policy | Requires "opt-in permission from the recipient confirming that they wish to receive subsequent messages," and says not to "spam, or surprise people" | A business may message someone only after they agree. A person who posts "does anyone know a good bookkeeper?" has not agreed to a pitch in their inbox, so answer in the group |
| Telegram Terms of Service | Users agree not to "use our service to send spam or scam users" | Scraping members and sending the same message breaks the terms |
| Telegram spam FAQ | Private messages are judged by the receiver's reaction, whatever the content; contacting strangers is a major trigger for reports; limits run from a few days for a first offense to a permanent loss of the ability to message strangers for repeats; group moderators are more lenient but unsolicited ads still lead to limits | One message to a stranger, reported, can limit the account |
These are platform rules. They are separate from the law. This page is about one person talking to people in a group, not about bulk texting, which has its own legal rules. If you plan a mass-message program to consumers in the United States, get advice on the Telephone Consumer Protection Act first.
Five minutes a day for two weeks
- Minute 1 to 3: Scroll back to the last day of messages in each of your three groups. Mark questions that you can answer in three sentences.
- Minute 4: Answer one, in the group, with the answer itself and nothing else.
- Minute 5: Write down who asked, what they asked and what happened, in a sheet with one row per person.
After two weeks you will be a familiar name to the regulars, and you will have a short list of people who asked questions in your area. That list is your pipeline, and none of it needed a private message.
Turning a question into a conversation
Imani is a made-up bookkeeper who works with online store owners. Someone in a WhatsApp group for shop owners writes: "My sales tax filings are a mess and I don't know where to start."
Start by listing every state where you've crossed the threshold for registering, then get the filing frequency each state assigned you. That's the first page of any clean-up. If you want, I can share the one-page checklist I use. Say so here or reply to this message and I'll post it for everyone.
The reply gives a real next step, offers more and asks the group's permission, not the person's inbox. If three people say yes, you post the checklist in the group with your name on it. Some of them will message you. A person who writes to you first has started the conversation, and Telegram's FAQ says even a limited account can still reply to people who message it first. From there:
Thanks for writing. To point you at the right thing: which states are you registered in, and are the filings monthly or quarterly? Once I know that, I can tell you if the clean-up is an hour of work or a week.
Move it to email within a few messages
Chat apps are a poor place to hold a business relationship. Messages get lost, there is no record, and the person can mute you. After two or three exchanges, suggest a short email with the details: "Easier to send you the checklist and a quote by email, what's the best address?" Once you have the address, your follow-up is an ordinary business email, and the FTC's CAN-SPAM guide for businesses applies to it: accurate sender and subject, your postal address and a working opt-out, honored within 10 business days. The guide says the law makes no exception for business-to-business email.
What gets you muted, limited or removed
- Posting your offer, link or phone number in the group when it was not asked for. Many groups ban it outright in the pinned rules.
- Adding people to other groups without their say.
- Sending the same private message to members you pulled from the list.
- Answering with a link and no answer.
- Replying to every question within seconds with a pitch.
When this is the wrong channel
Groups work for buyers who talk in groups. If your buyers are corporate procurement teams, hospital administrators or anyone whose job is to avoid unknown messages, you will find them on LinkedIn, by email or in a place like Slack communities, which work on the same principles with better moderation, as do Discord servers. A group is also slow. Expect a few conversations in the first month, not a pipeline.
Rocketship, which we make, does not search Telegram or WhatsApp. It does the email side after you have names: describe who you want in plain words and it finds the people, reads each one's website, emails them from your own Gmail, follows up and books the meeting. Its Conversations feature finds public posts on Reddit, Quora and LinkedIn where people ask for what you sell, and drafts a reply for you to send.
