Get StartedFrequently Asked Questions
What is a good WhatsApp opt-in rate?
For website widgets, a 2–5% click-through rate is typical, with 60–80% of those completing the opt-in. For customer opt-in at checkout or post-service, 30–60% is typical. Combined, well-optimized businesses add 200–500 new WhatsApp subscribers per month per 1,000 monthly customers.
How do I increase my WhatsApp opt-in rate?
Top tactics: position the widget above the fold on your website homepage, use a compelling CTA ("Get exclusive WhatsApp offers" beats "Subscribe"), add opt-in to checkout forms, train staff to ask customers verbally, and run WhatsApp-exclusive deals to incentivize opt-in. Reputoo provides opt-in widgets for all these touchpoints.
Does a larger WhatsApp list mean more revenue?
Yes, if the list is engaged. A list of 5,000 opted-in customers at industry average conversion rates (2–4% per campaign) generates significant monthly revenue from each broadcast. However, list quality matters more than size — a small highly engaged list outperforms a large disengaged one.
How do I prevent opt-out rates from eroding my list?
Send valuable, relevant messages (not just promotions), maintain proper frequency (max 2–4 messages per month for promotional content), always include easy opt-out ("Reply STOP"), and personalize messages. High-value lists with low opt-out rates grow steadily over months and years.
Is there a limit to how large my WhatsApp list can be?
No. The WhatsApp Business API supports lists of any size. Large brands run WhatsApp marketing to lists of millions. Your daily sending limit starts at 1,000 and increases over time based on message quality. Reputoo handles all limit management automatically.
