Where do you get the audience for targeting?
We use two main sources:
1. We get audience from other Telegram groups. We select groups based on interests and / or geographical location. We parse members, sort out active members who have been recently online, remove group admins and invite these selected members to join your group.
2. We get audience from other online sources where users publicly disclosed their telegram contact information. Such may be all kinds of listings, buy/sell trading websites and others. We follow the same process before inviting such audience into your group as described above.
