Frequently asked questions about cross-border delivery | Number outage detection to solve empty number interference
When doing cross-border promotion, especially when sending text messages, WhatsApp private messages, advertising, or social platform diversion to overseas markets, the most common problems encountered are: users do not respond, delivery fails, and data cannot be verified. Many people will attribute these phenomena to content problems or inaccurate delivery strategies, but one of the real underlying reasons is that these mobile phone numbers themselves are empty, out of service, or have expired. This is why one thing must be done before cross-border launch: number outage detection. If the user data in your hand is used directly for delivery without being tested, more than 30% of the operations may be "wasted budget".
