# Long-term subscription messages (users subscribe via popup)

A one-time subscription message can meet the needs of most service scenarios of the Mini Program, but there are scenarios that cannot be met by a one-time subscription in the field of offline public services, such as flight delays, and multiple message reminders need to be sent according to the real-time dynamics of the flight. In order to facilitate the service, we provide a long-term subscription message, the user subscribes once, the developer can issue multiple messages for a long time.

At present, long-term subscription messages are only open to offline public services such as government affairs and people's livelihood, medical care, transportation, finance, and education, and will gradually support other offline public service businesses in the later period.
