Telegram
Also known as: Telegram Channel, Telegram group, Telegram bot, Telegram messenger, Secret Chat (Telegram)
Telegram is a cloud-based messaging app known for its large group capacity (up to 200,000 members), broadcast Channels, strong encryption options (Secret Chats use end-to-end encryption), and permissive content moderation compared to competing platforms.
Founded by Pavel Durov, Telegram has approximately 900 million monthly active users. It is used for private messaging, community groups, news channels, activist coordination, customer support bots, and has been controversially used for spreading misinformation and organizing criminal activity due to its limited content moderation. Telegram monetizes through Telegram Premium subscriptions and Stars (digital currency for content purchases).
Telegram, explained at three levels
At home
Telegram is a messaging app similar to WhatsApp, but with some key differences: Telegram groups can have up to 200,000 members (WhatsApp limits groups to 1,024), Telegram Channels let anyone broadcast messages to unlimited followers (like a newsletter sent as messages), and Telegram stores all your messages in the cloud so you can access them from any device. You can also send files up to 2GB in size. Telegram's default messages are not end-to-end encrypted (they are encrypted but accessible to Telegram), though 'Secret Chats' turn on full end-to-end encryption.
At work
Telegram is used professionally for: large community groups for customer support or product communities (the 200,000 member limit accommodates large audiences), broadcast Channels for announcements or newsletters (organizations push updates to subscribers), bots (automated features that can handle customer inquiries, run polls, manage membership, or integrate with external services), and secure internal communication in markets where other messaging tools are restricted. Many crypto and blockchain projects use Telegram as their primary community platform.
At home
Telegram's default mode is cloud-based encrypted storage (messages are encrypted on Telegram's servers but Telegram technically has access). Secret Chats are different: they use end-to-end encryption (only the sender and recipient can read messages, not Telegram), do not allow forwarding, and can be set to auto-delete. Understanding this distinction matters for privacy: regular Telegram messages are not fully private from Telegram itself; Secret Chats are. For truly private communication, Signal (which is end-to-end encrypted by default for all messages) is more appropriate.
At work
Telegram bots are automated accounts created using the Telegram Bot API. They can handle customer service (answering FAQs), content delivery (sending media or documents), community moderation (removing spam, welcoming new members), polls and surveys, payment processing (Telegram supports in-bot payments via Stripe), and integration with external systems (sending alerts from monitoring tools, CRM updates, etc.). Telegram bots are relatively easy to build with the public Bot API and are widely used for automating community management at scale.
At home
Telegram's permissive content policy (relative to other major platforms) has made it a platform of last resort for content removed elsewhere: extremist groups, misinformation spreaders, scammers, and criminal networks have used Telegram Channels to reach large audiences outside of mainstream platform moderation. This raises platform liability questions: when does a messaging platform become responsible for content distributed through it? Durov's 2024 arrest in France was the most significant test of this question, potentially establishing legal precedents for messaging platform operator liability in democracies.
At work
Telegram's infrastructure for large communities -- unlimited Channels, 200,000-member groups, robust bots, and file sharing -- makes it technically superior to WhatsApp and competing platforms for community management at scale. The privacy reputation (though nuanced) and permissive content policy have also attracted communities in markets where other platforms are censored or restricted. For organizations operating in Southeast Asia, Central Asia, the Middle East, or Eastern Europe, Telegram is often the dominant messaging platform and community tool, making it essential infrastructure even for brands that don't actively cultivate a Telegram presence.
Real-world examples
At home
Jerome joined a Telegram Channel run by a journalist covering Eastern European politics. The journalist posted breaking news analysis directly to the Channel, which appeared as messages in his Telegram app. He found this faster and more reliable than Twitter for news from that region, and the Channel had 50,000 subscribers. He also noticed that activists he followed had shifted from Twitter to Telegram Channels after repeated account suspensions on Twitter.
At work
Marcus managed a crypto project's community. He ran a Telegram Group of 15,000 members for general discussion and a Telegram Channel of 45,000 subscribers for official announcements. He set up moderation bots to automatically remove spam and scam messages (a constant problem in crypto communities). When a technical issue occurred with the project's platform, he sent an update to the Channel immediately, reaching all 45,000 subscribers within seconds -- faster than any alternative communication channel.
Common confusions
- Many users assume Telegram is always fully encrypted and private — Telegram's default messages and groups are NOT end-to-end encrypted -- they are encrypted in transit and stored encrypted on Telegram's servers, but Telegram itself can access them. Only Telegram's 'Secret Chats' feature offers true end-to-end encryption where Telegram cannot access the content. This is a critical distinction: for conversations requiring genuine end-to-end privacy, Signal is the appropriate tool (all Signal messages are end-to-end encrypted by default). Telegram's privacy reputation is partly based on its resistance to government requests, not its default encryption model.
- Some assume that joining a Telegram Channel requires sharing your phone number with the Channel administrator — You can join Telegram Channels and Groups without your phone number being visible to other members or administrators (you appear as a username or your display name, not your phone number). However, Telegram itself has your phone number linked to your account. In private chats, your phone number may or may not be visible depending on your privacy settings -- you can set Telegram to only show your number to your existing contacts, or to nobody. The privacy defaults have changed over versions, so checking current privacy settings is important.
For analysts
When a client in crypto, financial services, media, or a region where Telegram is dominant asks about community building, Telegram should be part of the platform mix. The technical capabilities (large groups, Channels, bots, file sharing) are genuinely superior for broadcast community management. The key operational consideration is scam and spam management: Telegram communities in financial and crypto contexts require dedicated moderation bots and human moderators because scammers targeting community members are pervasive. Budget for moderation infrastructure before launching a large-scale Telegram community.
History & origin
Pavel Durov and his brother Nikolai founded Telegram in 2013, motivated partly by privacy concerns after Russian authorities pressured Durov to hand over user data from VKontakte (Russia's dominant social network, which Durov had founded). Telegram's design -- cloud-based with optional end-to-end encryption, large groups, fast performance, and unlimited cloud storage -- made it technically superior to WhatsApp in several dimensions. Telegram grew rapidly in regions where WhatsApp was restricted (China, Iran) and during periods of political unrest where activists needed reliable, private communication. Telegram became the go-to platform for political organizing across many countries and for cryptocurrency and NFT communities (2020-2022). Pavel Durov was arrested in France in August 2024 on charges related to Telegram's failure to moderate criminal activity on the platform -- a pivotal moment for platform liability debates around encrypted messaging. The arrest prompted Telegram to announce more active cooperation with law enforcement and content moderation changes.
