Telegram bot notification best practices: friendly bot sending messages, bell toggle, clock and heart

Content owner: Adsun Editorial & Ad Operations Team · Last verified: 2026-10-18

Quick answer

Telegram bot notifications work when every message is useful, timely and expected. Send only when you have something valuable — a reward ready, an event starting, a reply — segment users by behaviour, schedule by local time zone, and let users control frequency. Watch block rate and click-through after each broadcast: rising blocks mean you are sending too often or too generically. Sponsored bot messages, like those from Adsun, should be clearly marked and frequency-capped so they add revenue without driving users away.

Key takeaways

Every notification needs a clear reason to exist.
Segment by behaviour and send by local time.
Give users notification settings and an easy opt-out.
Track block rate after every broadcast.

Why notifications make or break bots

A bot's message history is its retention engine. Thoughtful messages bring users back daily; spam leads to blocks, which remove that user from your audience permanently.

Content users welcome

Personal updates: rewards ready, replies, order status.
Time-sensitive events and limited offers.
New features explained in one line with a button.
Weekly summaries instead of many small pings.

Frequency and timing

Start conservatively and increase only if block rate stays low.
Send in daytime hours of each user's time zone.
Respect Bot API rate limits when broadcasting.
Avoid back-to-back messages; combine updates.

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 tests $250 across 3 countries at a $0.05 CPC = 5,000 clicks; 38% reach the page = 1,900 visitors; 6% leave a lead = 114 leads at ≈ $2.19 each. A publisher with 8,000 daily users showing 1.5 ads each = 12,000 impressions; at a $1.20 eCPM that is about $14 a day. Replace every figure with your own data.

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.
