Each plan has a member limit per group: Free 1,000, Pro 25,000, Business unlimited. Going over it never stops protection — you get a dashboard banner and one bot message suggesting the right plan. On Pro and Business you can add extra groups for $19/month or $190/year each. Broadcast DMs use a monthly quota plus optional credit packs, and uploading a Telegram export to train your group's ML model can earn you bonus subscription days.

Open in your dashboard1Member limits on each plan
Each plan covers groups up to a certain size: Free up to 1,000 members, Pro up to 25,000, and Business has no member limit. The limit applies to each group, and a channel with its linked discussion group counts as one group.
The limit is a signpost, not a wall. Nothing is added to your bill when a group gets bigger — the limit only tells you which plan fits the group. When you are ready to move up, see How to change your plan.
2When a group grows past its limit
Going over a member limit never stops or weakens protection: moderation, rules and spam detection keep working exactly as before.
When a group passes its limit, the owner sees a banner in the dashboard and gets one message from the bot suggesting the plan that fits. Both are only a suggestion: you decide whether and when to upgrade, and the group stays protected in the meantime.
- Free group past 1,000 members: the bot suggests Pro
- Free or Pro group past 25,000: the bot suggests Business
- Business: no member limit, so no suggestion is ever sent
3Extra groups on Pro and Business
A Pro subscription includes one group and a Business subscription includes five. Need more? Add extra groups to the same subscription for $19/month or $190/year each — the same price on Pro and Business. Each extra group gets the plan of the subscription and keeps its own quotas.
Extra groups follow the subscription's billing cycle (monthly extras on a monthly plan, yearly extras on a yearly plan) and renew together with it. Buying an extra place by card charges the prorated amount for the rest of the current period right away; the dialog shows the amount before you confirm, and if the card is declined, no place is added.
Removing a group lowers the number of extra places charged at your next renewal. There is no refund for the current period, but the freed place stays available until the period ends, so re-attaching a group before then costs nothing.
- Pro: 1 group included, plus extra groups at $19/month each
- Business: 5 groups included, plus extra groups at $19/month each
- Yearly billing: $190 per extra group, about $15.83/month
- Crypto-paid subscriptions can buy extra places too, prorated for the remaining period; with less than 72 hours left before renewal, renew first
- Extra groups are sold on the website by card or crypto — not in the mobile app, and not on trials or manually granted subscriptions
4Broadcast DM quota and credits
Direct-message broadcasts use a monthly quota included with your plan: Pro includes 2,500 DMs per month and Business includes 10,000 per month for each group. Each message you send comes out of that monthly quota first.
When the monthly quota runs out, sends draw from credit packs you have bought, oldest first. Credit packs are a one-time purchase and do not expire each month the way the quota does.
- Small pack: $5 for 2,500 messages
- Large pack: $15 for 10,000 messages
5ML imports and bonus days
Telm can train a personal spam-detection model for your group from a Telegram chat export you upload. It checks the file, pulls out examples and trains the model in the background.
A completed import can earn you bonus days that extend your paid subscription, as a thank-you for contributing training data. The bonus is added to your subscription period automatically once the import finishes successfully.
6How the extras are billed
Extra groups are recurring and ride on the same subscription and billing date as your plan, so they renew together. When you switch between monthly and yearly billing, they move to the same cycle, and when you move from Pro to Business, the first five groups are included and any beyond five stay as extra places.
Broadcast credit packs are separate one-time charges. ML import bonus days shift your subscription end date rather than adding a charge. Everything shows up in your group's billing history.
