Insights
How do I use filters to find inactive contacts?
Use the Last Inbound Message At filter and select "31 - 180 days" or "181 - 365 days" to identify contacts who haven't interacted in a while. You can then send a targeted broadcast to re-engage them
How do I avoid sending messages to irrelevant contacts?
Use Including Labels and Excluding Labels together. For example, include "VIP Customer" and exclude "Unsubscribed", to ensure the broadcast only reaches your intended audience.
What is the Do-not-call filter for?
iSlash AI is integrated with the Hong Kong government's Do-not-call Registry. Before sending a broadcast, select "Not Registered" to exclude registered contacts and ensure your broadcast complies with Hong Kong regulations.
