When a user initiates a conversation, you can reach back out to them within 30 days of the user's last message. However, you must have a clear reason for contacting them. Your message should serve the user's interests and never spam them.
Users can also restart the conversation. When they do, provide a simple note of recognition to acknowledge their return.
- "Welcome back"
 - "It's great to chat with you again. How can I help?"
 
Here are some reasons to meaningfully re-engage with users:
Keep users informed
- Preview a new product launch.
 - Let the user know about special holiday hours.
 
Drive conversion
- Remind the user about a product they were exploring and encourage them to add it to their basket.
 - Let them know if something is back in stock.
 - Follow up after a free trial.
 
Proactively manage post-sales
- Let the user know when their order has shipped.
 - Encourage them to leave a review.
 
Manage appointments
- Send appointment reminders.
 - Allow users to check in online.
