Best Practices When You Automate WhatsApp Messages

Before you automate WhatsApp messages to anyone:

Get explicit opt-in (not just implied)
Explain what messages they'll receive
Make opt-out easy and obvious
Honor unsubscribe requests immediately

2. Personalize Your Automated Messages

Bad automated message:

Hi Customer, check out our sale!

Good automated message:

Hi {{first_name}}, based on your recent purchase of {{product}},
you might love these similar items - now 20% off!

3. Time Your Automated Messages Well

Respect business hours (9 AM - 8 PM local time)
Consider recipient time zones
Don't send late night/early morning
Space out messages appropriately

4. Maintain Quality Rating

When you automate WhatsApp messages at scale:

Start with low volume, increase gradually
Monitor your quality rating
Remove contacts who don't engage
Don't send to cold lists

5. Provide Clear Value

Every automated WhatsApp message should:

Be relevant to the recipient
Provide clear value
Have a specific purpose
Include appropriate CTA

6. Set Up Human Escalation

Automated WhatsApp messages can't handle everything:

Route complex queries to humans
Set up escalation triggers
Respond to live conversations promptly
Don't leave customers stuck with a bot
