Lead generation through Telegram Ads

A client approached me who needed to load his sales department with quality leads.

While thinking about the promotion strategy, I concluded that with the presence of a channel and budget, clients can be attracted through Telegram Ads.

Briefly about the numbers over 24 days:
Budget - 1349.17€
Subscribers - 1188
Cost per subscriber - 1.14€
Leads - 160
Cost per lead - 8.43€

The client was satisfied with the quality, although the price is slightly higher than from other sources. BUT, this is the price for a potential client who subscribed and wrote, and there are also leads that are just sitting in the channel, warming up and will write in 7-14-21-28 days.
