Telegram suits coaches who run a community and want free, automated replies with no 24-hour limit once a lead starts the chat. WhatsApp suits leads who already live in it, but automated messages are billed per message and follow-ups after 24 hours need paid templates. ## Key takeaways - Telegram lets leads and coaches talk by username with phone numbers hidden by default. WhatsApp usernames aren't launched yet. - Telegram groups hold up to 200,000 members and channels have no subscriber cap. WhatsApp groups hold up to 1,024. - Telegram's bot platform is free and has no reply window, but a lead must message the bot first. WhatsApp's Business Platform bills per message, with a 24-hour window and templates outside it. - WhatsApp chats are end-to-end encrypted by default, except business chats hosted by Meta. Telegram does that only in Secret Chats. - On SetLuca, Telegram is live today and WhatsApp is coming soon. --- Telegram vs WhatsApp comes up once leads start asking to move off Instagram. Both apps can carry a sales conversation, but they differ on privacy, group size, automation (software that sends replies for you), cost and audience. This guide compares them for one job: getting a lead from first message to a booked call. ## What's the difference between Telegram and WhatsApp for coaches? Telegram is a messaging app that stores chats in its cloud and is built around usernames, big communities and free bots. WhatsApp is built around phone numbers, most chats are end-to-end encrypted, and Meta bills for automated business messages. For a coach, that means Telegram is cheaper to automate and WhatsApp is easier to reach people on, depending on the country. Both apps need a mobile number to sign up, but Telegram lets you chat by username without showing it. The bigger difference for sales is automation. Telegram bots, automated accounts that reply for you, are free. WhatsApp's Business Platform, Meta's official system for business messaging, bills per delivered message and limits what you can send after 24 hours of silence. ## How do Telegram and WhatsApp compare side by side? Telegram wins on group size, free automation and username privacy. WhatsApp wins on default encryption and reach. Neither app is cheaper for every coach, because WhatsApp's charges depend on each lead's country. We checked each row against the companies' own pages on October 26, 2026. | Feature | Telegram | WhatsApp | | --- | --- | --- | | Who sees your number by default | Only people you've saved as contacts | People reach you by number until usernames launch | | Usernames | Yes, public usernames with a to z, 0 to 9 and underscores | Reservations open now; launch planned for later in 2026 | | Group size | Up to 200,000 members | Up to 1,024 members | | Broadcast channels | Unlimited subscribers | One-way channels; numbers hidden both ways | | Automation | Free Bot API; bots need no phone number | Business Platform (API) billed per delivered message | | Who starts the chat | The lead must message the bot first | Business can start, but only with a template | | Reply window | None stated for bots | 24-hour customer service window | | Default encryption | Cloud chats encrypted client to server; Secret Chats end to end | End to end for personal chats; Meta-hosted business chats are not treated as end to end | | In-chat payments | Bot payments with no Telegram commission; Stars for digital goods | Business Platform payments in some markets, such as Brazil | | US adult use (Pew 2025) | Not measured | 32% | ## Which app keeps your phone number private? Telegram does, today. By default, Telegram shows your number only to people you've saved as contacts. You can change that under Settings > Privacy and Security > Phone Number. People who already have your number saved will still see it. That matters if you sell from a personal account, because you can talk to hundreds of leads by username. Our [Telegram invite link guide](/blog/telegram-invite-link) covers every link type and how to tag them by source. ### What about WhatsApp usernames? WhatsApp lets people reserve a username now, to use when the feature launches later this year. An optional username key adds a second check before a stranger can reach you. Two limits stay in place. You still need a phone number to register, and a business that contacts someone for the first time still shows its phone number. On a personal number, that's a reason to keep a separate line. ## How big can groups and channels get? Telegram groups hold up to 200,000 members, and a Telegram channel can have an unlimited number of subscribers. WhatsApp groups hold up to 1,024 members. Both caps sit well above what a typical coaching group needs, so the gap matters mainly for big free challenges and launches. ### How do channels differ? WhatsApp Channels are a one-way broadcast for text, photos, videos, stickers and polls. Followers can't see the admin's number, and the admin can't see theirs. Telegram channels broadcast too, and many coaches pin a link in the channel that opens a one-on-one chat. Our [Telegram for coaching business](/blog/telegram-for-coaching-business) playbook covers when to run a group, a channel or both. ## Can you automate replies on Telegram and WhatsApp? Yes on both, through different doors. Telegram says its bot platform is free for both users and developers. WhatsApp automation runs on the Business Platform, where Meta has charged per delivered message since July 1, 2025. So automated Telegram replies cost nothing to send, while automated WhatsApp replies add a per-message bill. On Telegram, a bot is a special account that needs no phone number. It shows a "bot" label instead of a last seen status, so leads can see what they're talking to. Leads open the chat through a t.me link to the bot, and the bot answers from there. ### How does WhatsApp bill automated messages? Meta charges by message category and by the country code of the person receiving it. Service messages are your replies inside the 24-hour window that opens when a lead writes. Messages from leads to you are never charged. From October 1, 2026, Meta resumed charging for service messages, after the first 1,000 delivered each month per business phone number. Rates live in Meta's rate cards, its price lists. ## Does Telegram have a 24-hour window like WhatsApp? No. Telegram's bot docs set no reply window, so a bot can keep replying to a lead after a day or a week. The catch is that the lead has to write first. Telegram's bot documentation says, "Bots can't start conversations with users. A user must either add them to a group or send them a message first." WhatsApp works the other way around. When a lead messages or calls you, a 24-hour customer service window opens, and each new message from the lead resets it. Inside the window you can send any message. Outside it, Meta's docs say you can only send template messages, in the marketing, utility or authentication categories. A template is a message format Meta approves before you can send it. ### What does that mean for follow-ups? On WhatsApp, a lead who goes quiet for more than a day can only get a template, and each one is billed. On Telegram, a lead who started the chat can get a plain follow-up at no cost. Our [WhatsApp 24-hour window](/blog/whatsapp-24-hour-window) explainer covers templates in more detail, and our [DM follow-up sequence](/blog/dm-follow-up-sequence) covers what to say. ## Which app encrypts lead messages by default? WhatsApp does, for personal chats. WhatsApp turned on end-to-end encryption by default in 2016, group chats included. Telegram's default cloud chats are encrypted only between your device and Telegram's servers, so they aren't end to end. ### What changes for business chats? On WhatsApp, business chats depend on how the business runs them. When a business uses Meta as its cloud storage provider, WhatsApp says it does not consider the messages end-to-end encrypted. On Telegram, Secret Chats are end to end, but a lead talking to your bot is in a regular cloud chat. Whichever app you use, tell leads how you store their messages, and delete them when asked. ## Can leads pay you inside Telegram or WhatsApp? Sometimes, but most coaches shouldn't build their sale around in-chat payments. Telegram's Payments API, its official payment feature for bots, lets bots take payments through outside payment companies, and Telegram takes no commission. WhatsApp's Payments API is documented only for some markets, such as Brazil. Digital products are different on Telegram, where users buy them with Telegram Stars. Check Telegram's current rules before selling a course inside a bot. For high-ticket (high-priced) coaching, the call decides the sale and a payment link follows, so in-chat payments matter more for low-ticket (low-priced) offers. ## Where are your leads more likely to be? In the US, far more of your leads use WhatsApp than Telegram. Pew Research Center's 2025 survey found 32% of US adults use WhatsApp, up from 23% in 2021. White adults are less likely to use it than Black and Hispanic adults. Pew didn't measure Telegram in that survey, so the honest test is your own inbox. Count how many leads asked for each app last month. If leads ask for your number, they're probably WhatsApp people. If they already sit in Telegram groups, Telegram is the cheaper place to talk. Our guide to the [best DM channel for coaches](/blog/best-dm-channel-for-coaches) matches channels to niches in more depth. ## Which should you choose by niche and region? Choose the app your leads already open every day, then weigh cost and community. For most US coaches, that means Instagram first and WhatsApp on request. Telegram fits audiences already sitting in Telegram groups. Check this table against last month's leads. | Niche and audience | Region | Pick | Why | | --- | --- | --- | --- | | Fitness or nutrition, content-led | US, broad audience | Instagram first; add WhatsApp if leads ask | WhatsApp reaches about a third of US adults; Telegram isn't measured | | Business or career coaching | US, Hispanic or bilingual audience | WhatsApp | Pew finds Hispanic adults more likely to use it | | Any niche selling low-ticket offers in-chat | Brazil | WhatsApp | Meta documents Pix, payment links and boleto there | | Investing, tech or online business education | Leads already in Telegram groups | Telegram | Big groups, free bots, no reply window | | Group programs and challenges over 1,024 people | Any | Telegram | Groups hold up to 200,000 members | | Health or mindset with private disclosures | Any | WhatsApp, or the platform the lead picks | Personal chats are end to end by default | ## Worked example: one career coach, both apps This example is illustrative. Freya is a fictional career coach with leads in the US and Brazil. She has about 180 new lead conversations a month. She sends about six replies per conversation while the lead is active, so 180 x 6 = 1,080 replies. About a third of leads go quiet for more than a day, so 60 leads. She sends each of them two check-ins, days later. That's 60 x 2 = 120 follow-ups. ### What would it cost on WhatsApp? All 1,080 replies sit inside the 24-hour window, so they're service messages. The first 1,000 each month are free per number, which leaves 1,080 minus 1,000 = 80 billed. The 120 follow-ups fall outside the window, so each must be a template, and each is billed. That's 80 + 120 = 200 billed messages a month, at Meta's rate card for each lead's country. ### What would it cost on Telegram? The same 1,080 + 120 = 1,200 messages cost nothing to send through a bot. The trade-off is reach. Say only 120 of her 180 leads already use Telegram or will install it. Then 180 minus 120 = 60 leads, a third of her open leads, never reach her there. Freya keeps Instagram for discovery, runs her community and follow-ups on Telegram, and offers WhatsApp to the Brazilian leads who ask for it. ## Telegram vs Instagram: which is better for coaches? Instagram is better for being found, and Telegram is better for staying in touch. Most coaches need Instagram first, because Pew finds half of US adults use it. Telegram works as the second room, where a community or a long follow-up runs at no cost. On Instagram, a business can message someone only after they've messaged its professional account, and most replies must go out within 24 hours. Telegram bots have no reply window once a lead writes. Few people find a coach cold on Telegram, so the common setup is an Instagram link that opens your Telegram bot or group. Our [WhatsApp vs Instagram DMs](/blog/whatsapp-vs-instagram-dms) comparison covers the other half of that triangle. ## Where SetLuca fits, and where it doesn't yet SetLuca is live on Telegram, Instagram and Messenger in one inbox, and WhatsApp is coming soon. On Telegram, SetLuca replies to people who wrote to you first. Replies go out within minutes at any hour, paced like a person. Until WhatsApp launches on SetLuca, you answer WhatsApp leads yourself. It qualifies each lead with the sales framework you pick, a set of questions that shows whether a lead fits your offer. Then it books the call on Calendly, Cal.com, Google Calendar or your booking link. On every plan, it follows up on quiet threads up to three times (Telegram only for now) and stops the moment the lead replies. Auto-send is on by default, and you can switch any channel to review. ### What's the honest limit? A great human setter still reads hard, emotional conversations better. So SetLuca pins sensitive threads, such as medical issues or legal threats, to the top of your queue for a person to see first. SetLuca books the call, and you take it and close. Our [multi-channel DM playbook](/blog/multi-channel-dm-playbook) covers running Telegram next to your other channels. ## The verdict on Telegram vs WhatsApp For most coaches, Telegram vs WhatsApp isn't either-or. Use WhatsApp when your leads already live in it, and budget for templates after 24 hours. Use Telegram when you run a community, want free automated replies with no window, or need groups bigger than 1,024. Keep Instagram as the place people find you. If the Telegram vs WhatsApp choice adds WhatsApp to your setup, our [WhatsApp for coaches](/blog/whatsapp-for-coaches) guide explains message categories in plain words. For Telegram openers, see our [Telegram welcome message examples](/blog/telegram-welcome-message-examples). ## FAQ ### Is Telegram or WhatsApp better for coaches? It depends on where your leads are. WhatsApp is better if leads already use it daily, especially outside the US or in Hispanic communities. Telegram is better for communities, groups over 1,024 people and free automated replies with no 24-hour window. Many coaches use Instagram for discovery and one of these for follow-up. ### Is Telegram more private than WhatsApp? For phone numbers, yes. Telegram hides your number from non-contacts by default and lets people talk by username. For message content, WhatsApp is stronger: personal chats are end to end by default, while Telegram's default cloud chats aren't. Telegram's end-to-end Secret Chats are one-on-one and stay on one device. ### Does Telegram have a 24-hour messaging window? No. Telegram's bot docs don't set a reply window, so a bot can keep replying to a lead who started the chat. The rule that matters is the opposite one: a bot can't message anyone first. WhatsApp's Business Platform has a 24-hour window, and outside it you can only send templates. ### How much does WhatsApp cost for businesses? The Business Platform bills per delivered message, by category and by each lead's country, and has since July 1, 2025. From October 1, 2026, service messages are billed after the first 1,000 a month per number. Meta publishes rates in rate cards, so check the card for your leads' countries. ### Does SetLuca work on WhatsApp? Not yet. WhatsApp is coming soon on SetLuca. Telegram, Instagram and Messenger are live today in one inbox. SetLuca replies only to people who wrote to you first, qualifies them and books the call. Auto-send is on by default, and you can switch any channel to review. ## Sources 1. [Telegram, "Telegram FAQ." Retrieved 2026-10-26.](https://telegram.org/faq) 2.
