Voice message spam has become the primary tool for bypassing Telegram’s spam filters. Spam voice messages work where text-based methods have long ceased to deliver results. When you send an audio file instead of text, the system cannot check the content for prohibited words from blacklists.

Proper setup of voice spam yields a conversion rate 3-5 times higher than regular text mailings. Recipients open audio messages more often because the format builds more trust. At the same time, how to spam in TG via voice messages without triggering floodwaits and freezes remains a relevant question even for experienced marketers.

What Tools Are Used for Sending Voice Mailings #

Audio advertising requires specialized programs for automation. Standard Telegram clients, as well as unofficial ones, cannot handle mass sending of large volumes of messages—the IP address is quickly detected, leading to the loss of all accounts on the device. Professional tools operate through the official Telegram API with proxies and allow sending voice message spam across contact databases without restrictions or with minimal limits.

Voice marketing is built on three technologies:

• Programs for mass sending via Telegram API
• Audio file randomizers for creating unique versions
• MP3 to OGG/OPUS converters

The software connects to Telegram accounts and sends pre-prepared audio files to a list of recipients. Sending speed is regulated by timeouts between messages. Built-in anti-ban systems simulate normal user behavior.

What Are Voice Mailings and When to Use Them #

Voice advertising is a recorded audio message lasting 10-60 seconds. The format allows conveying emotions and intonations, which is impossible in text messages. Spam using voice messages is effective due to the impossibility of automatic content checking.

Scenarios for using voice mailings: #

First contact with cold audiences.

Voice messages are opened 4 times more often than text ones. People perceive audio as a personal appeal. Then, via auto-responder, a link to the offer or chat-bot is sent.

Invitations to webinars and events.

In handmade and self-employment niches, the format increases engagement by 40-60%. Listeners feel a personal invitation from the organizer. Registration conversion grows 2-3 times.

Mailings to thematic groups.

Moderators don’t have time to block audio messages as quickly as text with links. Telegram voice message spam passes checks because it lacks obvious advertising markers. The anti-spam system analyzes text, not audio.

Warming up new accounts.

Sending voice messages diversifies account actions. Telegram tracks bot behavior patterns. Rare actions like audio messages make the profile resemble a real user.

Technical Audio Formats: OGG and OPUS #

Telegram accepts voice messages only in OGG and OPUS formats. These codecs provide maximum compression while maintaining speech clarity. An OGG audio file weighs 5-10 times less than MP3 for the same duration.

Differences between OGG and OPUS. The OGG and OPUS formats are technically identical. OPUS is an audio codec, while OGG is a container for storage. An OPUS file is always packaged in an OGG container. The Telegram API requires exactly this combination.

A bitrate of 16-32 kbps provides an optimal balance of quality and size. The voice remains clear even on slow internet for the recipient. A 30-second file takes 60-120 KB.

Mono sound saves half the traffic compared to stereo. The difference in voice quality is unnoticeable to humans. A sampling rate of 16,000 Hz is sufficient for speech transmission.

Audio File Conversion. Record the message on a phone or computer voice recorder. Maximum conversion is achieved at 20-30 seconds duration. The first 10 seconds should contain the main offer hook.

Open the online converter Convertio to transform the file. Upload the MP3 recording and select OGG as the output format. The process takes 10-30 seconds depending on file size.

Randomize the source file using Delta Soft to create unique versions. It is recommended to generate one variation per 5-10 recipients. For a database of 1,000 contacts, create 100-200 unique files.

FFmpeg allows conversion via command line:

ffmpeg -i input.mp3 -c:a libopus -b:a 24k -vn output.ogg

The -b:a 24k parameter sets the bitrate to 24 kbps. The -vn key removes the video track if present. The result is ready for upload to mailing software.

Content Preparation for Voice Mailings #

The structure of the audio message determines the conversion to offer opening. Voice message advertising works according to the formula: hook — problem — solution — call to action. Each element takes a strictly defined time.

Scripts for Different Tasks

Cold contact via personal messages: “Found a Telegram promotion method that filters don’t block. It’s short voice mailings without links and prohibited words. Almost all recipients open them. Want to know details? Write me ‘Interested’.”

The format sparks curiosity with the novelty of the approach. Absence of direct sales reduces resistance. The call to action requires minimal effort from the recipient.

Invitation to a webinar for warm databases: “Tomorrow we’re holding a closed meeting on Telegram marketing. I’ll show how to do voice mailings with 80% open rates. Free session for entrepreneurs and self-employed. Register by replying ‘Want link’.”

Time limitation creates urgency. Mentioning the target audience increases relevance. Low entry threshold via free access boosts response.

Mailing to thematic groups: “Friends, testing a new format for voice mailings in Telegram. Audio without text and links isn’t blocked by moderators. You can see for yourself — I’ll leave result examples in post comments.”

The appeal creates a sense of community. Focus on results instead of product sales. Shifting the conversation to comments bypasses group publication restrictions.

Optimal Duration and Frequency

Maximum conversion is achieved at 20-30 seconds duration. Based on our experience, messages shorter than 15 seconds don’t fully reveal the offer. Audio longer than 40 seconds is listened to by less than 30% of recipients.

The first 10 seconds contain the hook-promise: “New Telegram mailing method not blocked by system filters.” Next 10 seconds reveal the mechanics: “Voice messages pass checks because they lack bad words and links.” Last 10 seconds address objections and give a call to action: “Our managers will help figure it out in 15 minutes. Send ‘Test’ for free access for three days.”

A four-element structure boosts response:

• What is it? (new mailing method)
• Why? (bypassing filters and high open rates)
• Why us? (tech support and result guarantee)
• Why now? (free test period)
  

Sending frequency starts at 5 messages per day from one account. In the absence of complaints, volume increases by 3-5 messages every three days. Maximum safe limit — 30-40 voice messages per day from a warmed-up account.

Tools for Mass Sending #

Voice spam software divides into two categories: programs with correct API requests and custom scripts. How to spam in Telegram via voice messages depends on choosing the right tool.

Requirements for Professional Software

Correct transmission of the audio file to Telegram servers prevents blocks. Most programs send files with empty sound waves. Telegram sees a mismatch between content and file metadata.

Telegram Prime forms requests with proper audio wave visualization. The recipient sees volume dynamics, like in a regular voice message. The anti-spam system finds no signs of automatic sending.

Working through the official API reduces proxy consumption by 3-4 times. Unofficial methods transmit excess data with each request. Load on the system decreases thanks to optimized exchange protocols.

Built-in randomization in Delta Soft alters files by three parameters:

• Weight (change by 1-5% via adding silence)
• File name (generation of random names)
• Duration (insertion of 0.1-0.3 second pauses)
• Comparison with Alternatives

Comparison with alternatives

Custom Python scripts on the Telethon library send files without wave metadata. Telegram marks such messages as suspicious from the first send. Blocking occurs after 10-20 messages.

Online mailing services add their own ads at the end of the audio message. Recipients immediately understand the mass nature of the mailing. Conversion drops by 60-80% compared to a personalized approach.

Telegram Prime allows taking a 72-hour test access. Checking sending correctness takes 1-2 hours of testing. Comparison with other solutions will show the difference in quality.

Step-by-Step Setup of Voice Message Mailings in Telegram Prime #

Step 1: Audio File Preparation

Recording the Voice Message

Record the advertising message on a phone or computer voice recorder. Optimal duration is 20-30 seconds. The first 10 seconds should contain the main offer hook.

Check recording quality before conversion. Extraneous noises and echoes reduce message perception. Recording is done in a quiet room without background sounds.

MP3 to OGG Conversion

Open the Convertio online converter in your browser. The service works for free for files up to 100 MB.

Sequence of actions:

1. Click the “Select Files” button and upload your MP3 recording
2. In the dropdown menu, select “OGG” as the output format
3. Click the red “Convert” button
4. Wait for the process to complete (10-30 seconds)
5. Download the ready OGG file to your computer
6. Save the file in a separate folder for easy access. Name the file clearly, e.g., “offer_original.ogg”.

Step 2: Audio File Randomization

Telegram detects identical files by hash and blocks mass mailings. Creating unique versions prevents duplicate detection by the system.

One variation is used for a maximum of 5-10 recipients. For a database of 1,000 contacts, 100-200 unique files are needed.

Working with Delta Soft

Download Delta Soft and install on your computer. The software works on Windows 10/Windows Server 2016 and above.

Launch the program and follow the instructions:

Open the “Audio Randomization” section
Click “Add File” and select your OGG file
Specify the number of variations (recommended: recipient database / 7)
Choose a folder for saving the result
Check all randomization parameters:
Duration change (adding 0.1-0.3 sec pauses)
File weight change (±1-5%)
Random name generation
Click “Create Variations”
The generation process takes 1-2 minutes depending on PC power. The program will create a folder with unique versions of your audio message.

Video on audio message randomization:

Result Check

Open the created folder with variations. Play 3-5 random files to verify. The content should remain identical to the original.

Check file differences by size. Each variation should differ by 500-3,000 bytes. Identical size indicates a randomization error.

Step 3: Mailing Setup in Telegram Prime

Open the required function depending on the mailing type (Telegram Prime must be running to open):

• Voice message mailing to DMs — http://localhost:21500/web/sendMessages.html
• Voice message mailing to chats — http://localhost:21500/web/sendChatMessages.html
• Sending voice messages to contacts — http://localhost:21500/web/sendMessagesContacts.html
• Voice message mailing to comments — http://localhost:21500/web/sendComments.html
• Auto-posting comments in channels — http://localhost:21500/web/sendAutoComments.html
• Voice auto-responder — http://localhost:21500/web/sendAnswers.html
• Sending audio messages to all open chats — http://localhost:21500/web/sendMessagesOpened.html

Find the “Work with Text” block in the program interface. Select the “Attach File” option from the dropdown menu. Click the browse button and navigate to the folder with randomized files. Select all OGG files and upload to the program. Telegram Prime will automatically distribute files among recipients. Each contact will receive a unique version of the audio message.

The software accepts links in any format:
@username
@username2
+79991234567
https://t.me/groupname
https://t.me/channelname
Copy the list from the collected database and paste into the “Recipient Database” field. The program will automatically count the number of contacts.

Delay between messages: 40-60 seconds
Messages from one account: 5. Safe amount for the first day. Increase by 3-5 messages every 3 days. Maximum 30 for warmed-up accounts
Launch Mailing
Process Monitoring

If errors appear, stop the mailing with the “Stop” button. Analyze the failure cause and adjust settings.

Strategies for Safe Mass Mailing #

How to spam via voice messages without blocks? This task requires following four anti-ban system rules. Each rule reduces account loss risk by 15-20%.

Rule 1: Targeting Relevant Audiences

Target audience parsing starts with analyzing thematic groups. Telegram Prime extracts chat participants, post commenters, channel commenters. Filtering by activity leaves users with last visit less than a week ago. Segmentation by interests increases relevance by 300%. A 10,000-contact database is divided into groups: beginner entrepreneurs, experienced marketers, specific niche representatives. Audio mailings are adapted for each segment.

Excluding inactive profiles saves resources. Accounts without photos, empty “About Me,” and zero subscriptions are ignored. Complaint probability from a real user is 5 times higher.

Rule 2: Offer Quality and Testing

Recording a test audio message is sent to 50-100 contacts manually. Measuring open rates and responses shows offer effectiveness. Conversion below 5% requires script rework.

The structure of a selling audio message includes four blocks of 5-7 seconds. First block grabs attention with a problem or intrigue. Second reveals the solution in simple words. Third addresses the main recipient objection. Fourth gives a specific call to action. A/B testing of message variants identifies the best script. The recipient group is split in half. Half listens to version A, the other half—version B. After two days, compare response numbers and transitions per call.

Intonation affects perception more than words. A confident calm voice builds trust. Artificial joy and pressure in the voice repel the listener. Recording is done after rehearsing the text 5-10 times.

Rule 3: Frequency and Limit Control

Warmed-up accounts handle 30-40 voice messages per day. New profiles start with 5 sends per day. Load increase happens by 5 messages every 3-4 days without blocks.

Timeouts between sends simulate human behavior. Minimum pause is 20-30 seconds. Maximum reaches 5-7 minutes. Random scatter prevents pattern detection.

Sending schedule excludes night hours from 00:00 to 07:00 since all spammers send at night and there’s high risk of hitting filters. Peak activity falls on 10:00-13:00 and 18:00-21:00. Distributing messages by time of day increases open rates by 25%.

Account rotation distributes load. A 5,000-contact database is divided among 10 accounts at 500 recipients each. Each profile sends 50 messages per day. Losing one account doesn’t stop the campaign.

Account Age	Messages per Day	Timeout (sec)	Ban Risk
7 days	5-10	15-30	High
8-30 days	15-25	10-20	Medium
31-90 days	25-35	5-15	Low
90+ days	35-50	3-10	Minimal

Rule 4: Audio File Randomization

Creating unique versions of the source file prevents hash detection. Delta Soft generates variations by changing duration, weight, name. One version is used for a maximum of 10 recipients.

Adding silence at the beginning and end changes duration by 0.1-0.5 seconds. Telegram calculates a different file hash with each duration change. Content remains identical for the listener.

Changing bitrate by 2-4 kbps creates a technically different file. Voice quality doesn’t change, but metadata differs. The system considers each variation a unique audio message.

Generating random file names hides connections between sends. Instead of “offer_v1.ogg,” use names like “rec_8h3f2k9s.ogg.” Timestamp in the name adds uniqueness.

Advantages of Voice Mailing Format #

Voice spam bypasses text filters of Telegram’s anti-spam systems. Algorithms check messages for keywords from the blacklist. Audio files lack indexable text for analysis.

Personalization through voice increases engagement by 200-300%. Text messages are perceived as mass mailings. Audio creates the illusion of a personal appeal to a specific person.

Absence of links excludes automatic blocking. Telegram marks messages with links as potential spam. Voice mailings deliver the offer without anti-spam triggers.

Emotional impact of voice influences decisions more than text. Intonation conveys the speaker’s confidence and expertise. Voice timbre evokes trust or rejection on a subconscious level.

Mass Voice Mailings — A Real Tool for 2025 #

Organizing voice mailings yourself is possible even on new accounts after a week’s warming. The format shows 3-5 times higher conversion than text messages. Combining with an auto-responder creates a full sales funnel.

Proper randomization setup prevents blocks on 80-90% of accounts. Targeting relevant audiences minimizes complaints. Gradual load increase allows scaling mailings to thousands of messages per day.
Voice message mailings remain the most effective method to bypass spam filters. Absence of text makes automatic content checking impossible. Visual sound wave creates the impression of a regular personal message.

A 72-hour test period allows checking the approach’s effectiveness. Comparison with text mailings will show differences in open rates and response. The right software and strategy yield results in the first week of use.
