A Telegram bot can only send a message to a user after that user has messaged the bot first, usually by tapping &#8220;Start&#8221; or following a link that opens the bot. There is no way to buy a phone number list and push messages onto it the way SMS or paid WhatsApp templates allow. Once someone has opted in this way, a bot can message them freely, subject to Telegram&#8217;s own rate limits: roughly one message per second per chat, and up to about 30 messages per second across a whole broadcast without paying Telegram anything extra, or up to 1,000 messages per second if the bot enables Telegram&#8217;s paid broadcast tier at a small per-message cost in Stars. The practical work in a Telegram program is less about sending capacity and more about getting people to open the bot in the first place, usually through a shared link, a QR code, or a prompt from another channel a business already owns.<\/p>\n\n\n\n<h2 id=\"tldr\" class=\"wp-block-heading\">TL;DR<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A Telegram bot cannot message a user who has never interacted with it. The user has to send the first message, commonly by tapping Start on a shared link.<\/li>\n\n\n\n<li>This makes Telegram closer to an email list or an app push token than to a phone number list. The audience has to opt in through the platform itself, not just through a form on a website.<\/li>\n\n\n\n<li>Telegram publishes its own sending limits: about one message per second in a single chat, about 20 messages per minute in a group, and about 30 messages per second for bulk sends without paying, or up to 1,000 messages per second on the paid broadcast tier.<\/li>\n\n\n\n<li>Growing the opted-in list is the actual bottleneck, and Telegram&#8217;s deep-link format (a URL that opens a chat and passes a parameter to the bot&#8217;s <code>\/start<\/code> handler) is the standard tool for doing that from ads, email signatures, QR codes, or a website.<\/li>\n\n\n\n<li>Telegram, SMS, WhatsApp, and RCS solve different problems. SMS reaches any handset without opt-in through the platform. WhatsApp and RCS sit between SMS and Telegram, each with their own opt-in and verification rules. None of the four is a drop-in replacement for another.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"telegram-messaging-here\" class=\"wp-block-heading\">What Telegram Messaging Means Here<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SMPPCenter&#8217;s <a href=\"https:\/\/smppcenter.com\/telegram-messaging-software\/\">Telegram messaging product<\/a> covers two related jobs: sending campaigns to a Telegram audience, and handling replies from that audience in a shared inbox. On the sending side, the platform supports text up to 4,096 characters along with photos, documents, and videos, plus reusable templates, inline link buttons, quick-reply keyboards, and a live preview that renders the message the way it will look inside Telegram before it goes out. On the receiving side, incoming messages land in a shared inbox that support agents can work from, with conversation assignment and permission controls for larger teams. Every send is tracked as sent, delivered, or failed, with logs and summary reporting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Getting connected is a short setup: a business creates its own bot through Telegram&#8217;s BotFather, then pastes that bot&#8217;s token into its account. From there, the platform registers and maintains the inbound webhook so the business does not need to run its own server for that piece. Developers can also trigger Telegram sends from external systems once API sending is turned on for the account, which lets Telegram sit alongside existing SMS and SMPP workflows rather than as a separate silo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">None of that description says anything about who a campaign can actually reach, and that is the part worth slowing down on, because it is where Telegram diverges hardest from the channels an SMS or WhatsApp buyer is used to planning around.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"opt-in-rule\" class=\"wp-block-heading\">The Opt-In Rule<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Every messaging channel has some version of consent built in. SMS technically allows sending to any number, with consent enforced by regulation and carrier filtering rather than by the protocol itself. WhatsApp&#8217;s Business Platform enforces a stricter model at the platform level: outside a short customer-service window opened by the user&#8217;s own message, a business can only reach someone with a pre-approved message template, and Meta&#8217;s own review process is the gate on abuse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Telegram enforces consent at an even more basic technical level. A bot&#8217;s messaging methods only work against a chat ID, and a chat ID only exists once a user has opened a conversation with that bot, most often by pressing Start. There is no API call that creates a new chat with a stranger. This is not a policy a business agrees to and can occasionally push against; it is how the platform is built. A phone number, an email address, or a CRM record is not enough on its own to reach someone on Telegram. The person has to take the first step inside Telegram itself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical result: a Telegram &#8220;audience&#8221; is really a list of chat IDs generated by people who already found and started the bot. Nothing else populates that list. A campaign tool can format, schedule, and track messages beautifully and still have nobody to send them to if audience growth was never planned as its own workstream.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"rate-limits\" class=\"wp-block-heading\">Rate Limits and Broadcast Math<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once someone has opted in, Telegram&#8217;s <a href=\"https:\/\/core.telegram.org\/bots\/faq\" target=\"_blank\" rel=\"noopener nofollow\">own bot FAQ<\/a> sets out the sending limits a bot has to work within:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Sending pattern<\/th><th>Published limit<\/th><\/tr><\/thead><tbody><tr><td>Single chat<\/td><td>About one message per second<\/td><\/tr><tr><td>Group chat<\/td><td>About 20 messages per minute<\/td><\/tr><tr><td>Bulk broadcast, free tier<\/td><td>About 30 messages per second across all chats<\/td><\/tr><tr><td>Bulk broadcast, paid tier<\/td><td>Up to about 1,000 messages per second, at roughly 0.1 Stars per message beyond the free 30-per-second allowance<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For a list of 100,000 opted-in users, the free tier&#8217;s roughly 30 messages per second works out to under an hour to clear the whole list, which covers the overwhelming majority of SMS-aggregator-scale Telegram campaigns without touching the paid tier at all. The paid tier exists for genuinely large broadcasts, or for a business that wants a single send to clear in minutes rather than the better part of an hour. Note that these are Telegram&#8217;s platform limits, not a number set by any individual software vendor; nothing published on smppcenter.com states a separate, lower ceiling specific to its own Telegram integration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These limits sit well above what most SMS operators are used to worrying about, since the constraint most SMS teams tune for is throughput on their own SMPP binds, not a hard platform ceiling. The Telegram constraint is closer in spirit to the discipline required around <a href=\"https:\/\/smppcenter.com\/kb\/control-throttling-over-smpp-connectivity\/\">SMPP throughput and throttling<\/a>: a documented cap exists, and campaign scheduling should respect it rather than assume unlimited send speed.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"growing-audience\" class=\"wp-block-heading\">Growing an Opted-In Audience<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Since a bot cannot reach anyone cold, the actual growth lever for a Telegram program is getting people to press Start in the first place. Telegram&#8217;s <a href=\"https:\/\/core.telegram.org\/bots\/features#deep-linking\" target=\"_blank\" rel=\"noopener nofollow\">deep-link format<\/a> is the standard mechanism for this: a URL shaped like <code>https:\/\/t.me\/your_bot?start=payload<\/code> opens a chat with the bot and passes whatever payload was appended, which the bot receives as part of its <code>\/start<\/code> command. That payload can identify which campaign, store location, or referral source produced the click, which gives a business the same kind of attribution it would expect from a tracked landing page link.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, businesses feed these links into channels they already control: a QR code on packaging or in-store signage, a link in an SMS confirmation message, a line in an email footer, a button on a post-purchase page, or a prompt inside a WhatsApp or web chat. None of that requires anything beyond a generated link and a place to put it, but it does mean a Telegram launch plan needs an acquisition step, not just a sending step. A business that skips this and only wires up the campaign-sending side of a Telegram integration will find the audience stays empty regardless of how good the message templates are.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cross-promoting from SMS or WhatsApp into Telegram, and vice versa, is a reasonable pattern precisely because the two channels fail differently: SMS reaches almost anyone but carries no rich formatting, while Telegram carries rich formatting and a persistent two-way thread but only reaches people who already opted in through the app.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"channel-comparison\" class=\"wp-block-heading\">Telegram vs SMS vs WhatsApp vs RCS<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A <a href=\"https:\/\/smppcenter.com\/journal\/rcs-business-messaging-beyond-smpp-connection\/\">separate comparison<\/a> already lays out SMS, RCS, and WhatsApp against each other on reach, verification, rich content, launch time, and encryption. Telegram adds a fourth column and, more importantly, a dimension that table does not need for the other three: how a business is even allowed to start the conversation.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Dimension<\/th><th>SMS<\/th><th>WhatsApp Business Platform<\/th><th>RCS<\/th><th>Telegram<\/th><\/tr><\/thead><tbody><tr><td>How a business reaches someone for the first time<\/td><td>Any valid number, consent enforced by regulation and carrier filtering, not the protocol<\/td><td>Pre-approved template message, gated by Meta&#8217;s review process<\/td><td>Verified brand agent, subject to carrier\/device support<\/td><td>Not possible; the user must message the bot first<\/td><\/tr><tr><td>Ongoing conversation<\/td><td>No special window; each message is independent<\/td><td>Free-form replies allowed inside a short window opened by the user&#8217;s message, otherwise templates only<\/td><td>Carrier-dependent, generally similar to WhatsApp&#8217;s session model<\/td><td>Unrestricted once the chat exists<\/td><\/tr><tr><td>Rich content<\/td><td>Text and links only<\/td><td>Images, video, documents, interactive buttons<\/td><td>Cards, carousels, suggested replies<\/td><td>Text up to 4,096 characters, photos, documents, video, inline buttons<\/td><\/tr><tr><td>Sender verification<\/td><td>None built into the protocol<\/td><td>Verified business account<\/td><td>Verified brand agent<\/td><td>Bot identity only; no phone-number-style business verification layer<\/td><\/tr><tr><td>Rate ceiling for bulk sends<\/td><td>Set by the operator&#8217;s own SMPP bind and throughput plan<\/td><td>Set by Meta&#8217;s messaging limits, which scale with account quality<\/td><td>Carrier-dependent<\/td><td>About 30 messages per second free, up to about 1,000 per second on the paid tier<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">SMS is the only one of the four that does not require the recipient to have opted in through the channel&#8217;s own app before a business can reach them for the first time. WhatsApp and RCS sit in between, gating the first message behind platform review rather than user action. Telegram is the strictest of the four on this specific point, which is also why it tends to work best as a companion channel for an audience a business has already engaged somewhere else, rather than as the first channel a new contact ever sees.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"two-telegram-features\" class=\"wp-block-heading\">Two Separate Telegram Features<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Two different things on SMPPCenter&#8217;s platform both involve Telegram, and they solve unrelated problems. The bulk messaging and shared inbox feature is a customer-facing channel: it sends campaigns to a business&#8217;s own Telegram audience and receives their replies. A <a href=\"https:\/\/smppcenter.com\/journal\/setting-up-telegram-webhook-interacting-bot\/\">separate feature<\/a> lets an account administrator connect their own Telegram account to receive operational alerts about their SMPPCenter account itself, using bot commands like <code>\/getdlrsummary<\/code>, <code>\/topuserssms<\/code>, <code>\/mytelegram<\/code>, and <code>\/banip<\/code>, along with <a href=\"https:\/\/smppcenter.com\/journal\/enhance-monitoring-hourly-summary-alerts-via-telegram-e-mail\/\">hourly summary alerts<\/a> sent alongside email. Getting a personal Telegram user ID, covered in a <a href=\"https:\/\/smppcenter.com\/kb\/how-do-i-get-my-telegram-user-id\/\">dedicated KB entry<\/a>, belongs to this second, internal-monitoring use case, not to setting up a customer-facing campaign bot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An operations team evaluating Telegram as a customer channel should not confuse the two. The monitoring bot is about an administrator watching their own platform account from their phone. The messaging product is about a business reaching its own customers or subscribers on Telegram. Neither setup process substitutes for the other.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"compliance-deliverability\" class=\"wp-block-heading\">Compliance and Deliverability<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because the opt-in step happens inside Telegram&#8217;s own app rather than through a form a business controls, most of the spam-prevention pressure that other channels put on the sender is absorbed by the platform itself before a message ever gets sent. That does not remove ordinary good practice: a user who no longer wants messages can block a bot at any time, which ends the conversation from Telegram&#8217;s side, and a bot that a meaningful share of its audience blocks in a short window is the kind of signal that tends to draw platform-level attention on any messaging system, Telegram included. Keeping unsubscribe or mute options visible inside the bot&#8217;s own command menu, and sending at a cadence a subscriber actually expects, does more for long-term deliverability than anything on the technical sending side.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For businesses already running NCPR or DND scrubbing on their SMS lists in India, that scrubbing logic does not carry over to Telegram, because the Telegram audience was never built from a phone number list in the first place. The two channels need entirely separate consent handling: one is governed by a national do-not-call registry tied to a phone number, the other by whether a specific Telegram account chose to press Start.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"next-steps\" class=\"wp-block-heading\">Next Steps<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A Telegram program only pays off once there is an opted-in audience to send to, so the planning work belongs upstream of the campaign tooling itself: where the Start links will live, and how many people are realistically expected to click them. Reviewing <a href=\"https:\/\/smppcenter.com\/pricing\/\">plan tiers and included channels<\/a> is a reasonable next step once that audience-growth plan exists, and the <a href=\"https:\/\/smppcenter.com\/why-us\/\">why-us page<\/a> covers how Telegram fits alongside SMS, WhatsApp, and RCS within one account rather than as a separate system to manage.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"faqs\" class=\"wp-block-heading\">FAQs<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can a Telegram bot send a message to any phone number, the way SMS does?<\/strong><br>No. A Telegram bot can only message a chat that already exists, and a chat only exists once the user has messaged the bot first, typically by pressing Start on a shared link.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What happens if a business tries to message someone who never started the bot?<\/strong><br>There is no chat ID to send to, so the message cannot be sent at all. This is not a filter that occasionally blocks a message; the API has no way to address a user who has not opened the bot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How fast can a Telegram bulk campaign actually send?<\/strong><br>Telegram&#8217;s own limits allow roughly 30 messages per second across a broadcast without any extra cost, which clears a 100,000-person list in under an hour, or up to about 1,000 messages per second on Telegram&#8217;s paid broadcast tier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Is a Telegram audience the same as an SMS or WhatsApp contact list?<\/strong><br>No. It has to be built specifically inside Telegram, one Start tap at a time, usually through a deep link shared from another channel. A phone number or email list does not transfer over automatically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Does the Telegram messaging product and the Telegram monitoring bot use the same setup?<\/strong><br>No. The messaging product connects a business&#8217;s own customer-facing bot for campaigns and support replies. The monitoring bot is a separate feature that sends an account administrator alerts about their own SMPPCenter account, using different commands and a different purpose entirely.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n","protected":false},"excerpt":{"rendered":"<p>Telegram bulk messaging works differently from SMS and WhatsApp because a bot cannot contact anyone who hasn&#8217;t messaged it first.
