Sending bulk messages to every member of a Telegram group is a task that requires careful consideration of Telegram's policies and features. You cannot simply send a private message to every member of a group without their prior consent or a special tool. Telegram's anti-spam measures are designed to prevent this type of activity.

Here are the most effective and common ways to send bulk messages, ranging from built-in features to third-party tools.

1. The Right Way: Using a Telegram Channel
The most effective and officially supported method for broadcasting messages to a large audience is to use a Telegram Channel.

How it works: Channels are designed for one-to-many communication, where only the channel owner or admins can post messages. Subscribers cannot post, but they can see the messages you send.

Benefits: You can reach an unlimited number of subscribers, and your messages will be sent to all of them instantly. This is the safest way to do mass messaging without violating Telegram's spam policies.

Strategy: Create a channel and encourage your group members to join it. Use the channel for important announcements and broadcasts, while keeping the group for two-way conversations and community building.

2. Using Third-Party Tools and Bots
Many third-party services and bots have been developed to automate the process of sending bulk messages. These tools often use the Telegram API to manage and send messages.

Broadcast Bots: These bots are designed to send automated broadcasts, announcements, and reminders to group members. Some, like TypeBot, even allow you to set up multi-step message flows with conditional logic, which can be useful for targeted communication.


Chrome Extensions & Desktop Software: There are various browser extensions and desktop applications that claim to automate bulk messaging. These often work by scraping member usernames from a group and then sending messages to them. However, you must be extremely cautious with these tools, as they can easily get your account flagged or banned for spamming.

Business-Oriented Platforms: For businesses, there are professional omnichannel platforms that integrate with the Telegram API. Services like ControlHippo or Respond.io allow you to manage bulk messaging campaigns, create message templates, and track analytics in a more controlled and compliant manner. These are often paid services.


Important Considerations and Warnings
Telegram's Anti-Spam Policy: Telegram has strict rules against unsolicited messages. Your account may be permanently banned if you are reported for spamming, especially if you are sending the same message to a large number of people who have not previously interacted with you.

New Account Restrictions: New Telegram accounts have lower limits on the number of messages they can send per hour or day. You must "warm up" a new account by engaging in normal, human-like activity before attempting any bulk messaging.

The "First Contact" Rule: Telegram bots are generally not allowed to initiate conversations with users. A user must send a message to your bot first before you can send them a message. This is a key measure to prevent spam.

Technical Knowledge: If you choose to use the Telegram API to create a custom script, it requires technical skills. Poorly configured scripts can lead to bans, and it is recommended to use trusted libraries and follow best practices to avoid triggering spam detection.
