What does the official account of real estate company WeChat do? Should I use a service number or a subscription number?

Because the real estate mainly focuses on publicity, we should choose the subscription number to send messages to customers once a day and the service number mainly provides service functions, but the publicity function is weakened to send messages once a month, but more services can be provided, such as online payment, bank account inquiry and so on. For example, I developed a public platform for logistics companies, because customers can only choose the service number if they want to query and track the goods information. I can collect some useful information every day and send it to all those who need it, so I choose the subscription number.
