Question 1

How many Telegram messages can I send in bulk per minute?

Accepted Answer

Across all chats, the Bot API caps you at roughly 30 messages per second (1,800/minute), but per-chat sends are limited to one message per second and per-channel broadcasts to 20 per minute. Real-world bulk schedulers should target ~25 messages per second cross-chat to leave headroom.

Question 2

Can I import a CSV directly into Telegram for bulk posting?

Accepted Answer

Telegram itself doesn't accept CSV uploads — you need a third-party scheduler with bulk-import support. The CSV is parsed locally, validated against your channel list, and then sent through the Bot API at a rate that respects flood control.

Question 3

What's the safest schedule cadence for bulk Telegram posts?

Accepted Answer

For most agencies, one post per channel per 60–90 minutes is a comfortable cadence that keeps subscriber notifications useful. Burst sending more often than that triggers unsubscribes long before it triggers Bot API limits.

Question 4

How do I avoid Telegram flood control during a large campaign?

Accepted Answer

Stagger posts by at least 90 seconds across the same chat, cap cross-chat throughput at 25 messages per second, and add exponential backoff on RetryAfter responses. A pre-flight dry batch to a test channel catches most flood-control conditions before they reach production.

Question 5

Does bulk messaging work for Telegram private chats too?

Accepted Answer

The Bot API allows it, but only chats where the user has actively initiated the conversation with your bot. Cold outreach to private DMs is forbidden by Telegram's Terms of Service and will get the bot banned within hours.

Question 6

What happens if a bulk-import row fails mid-run?

Accepted Answer

A well-designed scheduler retries transient errors (429 Too Many Requests, network timeouts) with backoff and quarantines permanent ones (invalid chat_id, blocked bot) for human review. Atomic per-row failures should never roll back the rest of the batch.
