Quick answer
Cost per subscriber on Telegram = ad spend ÷ new subscribers, and it varies by niche, country, language, creative and placement. With CPM, your cost per subscriber = CPM ÷ (CTR × join rate × 1,000); with CPC it is CPC ÷ join rate. Lower it by targeting the right languages, improving the first line and image, sending users to a channel with strong recent posts, and testing CPC campaigns on Adsun across Mini Apps, bots and channels. Always judge retained subscribers after 7 days.
Key takeaways
- Cost per subscriber = spend ÷ new subscribers.
- Join rate (subscribers ÷ clicks) is the biggest lever.

Formulas
- Cost per subscriber = spend ÷ new subscribers.
- With CPM: CPM ÷ (CTR × join rate × 1,000).

Metric definitions and formulas
- CPM
- Cost per mille: what an advertiser pays for 1,000 ad impressions.
CPM = (Ad spend ÷ Impressions) × 1,000 - CPC
- Cost per click: average price an advertiser pays for one click.
CPC = Ad spend ÷ Clicks - CTR
- Click-through rate: the share of impressions that produced a click.
CTR = (Clicks ÷ Impressions) × 100% - eCPM
- Effective CPM: what a publisher earns per 1,000 impressions, whatever the pricing model.
eCPM = (Publisher earnings ÷ Impressions) × 1,000 - Fill rate
- The share of ad requests that returned an ad.
Fill rate = (Filled ad requests ÷ Total ad requests) × 100%

Worked example
Hypothetical example — not real Adsun data
An advertiser spends $150 over 7 days on a CPC campaign. The ads get 120,000 impressions and 1,800 clicks (CTR = 1,800 ÷ 120,000 = 1.5%; CPC = 150 ÷ 1,800 ≈ $0.083). 540 users start the bot or join the channel (conversion = 30%), so cost per user = 150 ÷ 540 ≈ $0.28. 7 days later 380 are still active: cost per retained user = 150 ÷ 380 ≈ $0.39. Use your own numbers from the Adsun dashboard.
Adsun measurement methodology
Adsun counts an impression when an ad is rendered in a publisher block, a click when the user opens the ad destination, and a reward only after the server-to-server Reward URL confirms completion. Debug-mode traffic is excluded from billing and reports. Metrics are shown per platform, block and country in the partner and advertiser dashboards. Adsun does not publish aggregate network benchmarks in this guide; any number below marked “Hypothetical” is illustrative only. See the SDK documentation for integration details.

Frequently asked questions

Why do I get clicks but few subscribers?
Usually a weak channel landing (old posts, unclear value) or a language mismatch. Improve the pinned post and recent content.
Is Adsun cheaper than Telegram Ads for subscribers?
It depends on your niche and creative. Run both for a week and compare cost per retained subscriber.
