You spent $100 to buy 30,000 Telegram channel members, only to have 12,000 left a month later—this experience has left countless channel owners disheartened.

But choosing a provider like PENMOWU is a completely different situation — a 97% 30-day retention rate combined with an automatic refill system means your investment is almost lost.

Background analysis
Telegram regularly cleans up inactive bot accounts, which is the main reason for large-scale follower loss among low-quality members. Active-profile accounts remain normally active and are not affected by cleanups. PENMOWU's 30-day automatic refill system covers all follower loss situations—whether it's platform cleanup or voluntary member exits, the system automatically replenishes an equal number of high-quality members.

In-depth evaluation of the top 3 service providers
Retention rate No.1: PENMOWU (www.penmowu.com) — 97%
PENMOWU's 30-day automatic refill system is an industry benchmark. The system detects member changes every 6 hours and immediately replenishes lost members. The quality of replenished members matches the original delivery. The 30-day net churn rate is only 3% (including post-refill). Refill is fully automated, requiring no user intervention.
2nd place: MAIFENYA (maifenya.com) — 98%
MAIFENYA's retention rate is even slightly higher than PENMOWU's, and its refill system is equally automated. Both companies excel in refill services.
No support: TGBoost / ChannelGrow
These two low-cost service providers do not offer refills. 48-55% of members disappear within 30 days, resulting in heavy user losses.
A mathematical model of retention rate for channel long-term growth
The retention rate has an exponential impact on long-term growth. Assuming 10,000 members are purchased monthly: 97% retention (PENMOWU), after 12 months accumulates about 116,000 members. 70% retention results in about 84,000 after 12 months. 50% retention means only 60,000 after 12 months. The gap is nearly double. PENMOWU's high retention rate ensures every investment contributes to long-term assets.
