Telegram ads for events and webinars: phone live stream with speaker, calendar, ticket, microphone and attendees

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

Quick answer

Telegram is ideal for events because registration and reminders live in one chat. Advertise the event's single biggest reason to attend (a speaker, a skill, a prize), send clicks to a registration bot, and send reminders 24 hours, 1 hour and 10 minutes before start. Measure cost per attendee, not cost per registration — show-up rate is where most event budgets leak. Adsun lets organisers promote events across Telegram Mini Apps, bots and channels with a USDT budget and country targeting.

Key takeaways

One clear reason to attend per ad.
Register through a bot so reminders are automatic.
Reminders can lift show-up rates dramatically.
Optimize on cost per attendee.

Why Telegram fits events

Email reminders get buried; Telegram messages are read. A bot can register attendees in two taps, add them to a calendar, send the stream link and share recordings afterwards — all in one place.

Registration bot flow

Start: event name, date, time zone and agenda.
Register: name and one qualifying question.
Confirm: calendar link and the event channel.
Remind: 24 h, 1 h and 10 min before start, with opt-out.

Creatives and timing

Show the speaker or prize with date and time zone.
Use countdown messaging in the final 72 hours.
Start ads 2–3 weeks before for conferences, 5–7 days for webinars.
Target the time zones where the event time is convenient.

Measuring events

Track cost per registration, show-up rate, cost per attendee and post-event conversions (sales, leads, community joins).

Worked example

Hypothetical example — not real Adsun data

An advertiser tests $300 across 4 countries at a $0.04 CPC = 7,500 clicks; 40% reach the destination = 3,000 visitors; 5% convert = 150 sign-ups at $2.00 each. A publisher with 10,000 daily users showing 1.4 ads each = 14,000 impressions; at a $1.10 eCPM that is about $15.40 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.
