Common Mistakes to Avoid

Learn from others' mistakes to avoid costly errors

Sending Too Many Messages

Bombarding customers with frequent messages leads to unsubscribes and poor reputation.

✅ Solution: Limit promotional messages to 1-2 per week and focus on quality over quantity.

Ignoring Opt-out Requests

Not honoring unsubscribe requests violates WhatsApp policies and damages your reputation.

✅ Solution: Implement automatic opt-out processing and respect all unsubscribe requests immediately.

Using Generic Content

Sending the same message to everyone reduces engagement and feels impersonal.

✅ Solution: Personalize messages using merge tags and segment your audience for targeted content.

Poor Timing

Sending messages at inappropriate times reduces open rates and annoys recipients.

✅ Solution: Send messages during business hours and consider the recipient's timezone.

Not Testing Campaigns

Sending untested campaigns can lead to errors, poor formatting, or broken links.

✅ Solution: Always test campaigns with a small group before sending to your full audience.

Ignoring Analytics

Not monitoring campaign performance means missing optimization opportunities.

✅ Solution: Regularly review analytics data and use insights to improve future campaigns.
