Is anyone else facing scaling issues after moving to the official WhatsApp Business API?
We recently shifted from basic WhatsApp marketing tools to the official API setup, and while the delivery + automation is much better, scaling campaigns has introduced a lot of unexpected issues.
Some things are working well so far:
- Better message deliverability compared to unofficial tools
- Automation flows feel more stable
- Customer replies are much faster than email
- API integrations with CRM/helpdesk are smoother
- Broadcast targeting is cleaner with proper opt-ins
But a few pain points are becoming difficult:
- Template approvals/rejections feel inconsistent
- Quality rating drops are hard to predict
- Costs increase very quickly at higher volume
- Webhook reliability sometimes becomes an issue
- Multi-agent inboxes still feel clunky on many platforms
One thing I’m curious about:
For people here, sending large-scale campaigns regularly:
- How are you maintaining good quality scores?
- Are you using Meta directly or through BSPs?
- Any strategy to improve template approval rates?
- What’s your current biggest bottleneck with WhatsApp API?
Would love to hear real experiences from people actively running WhatsApp campaigns at scale.
