Which company is the best SMS group sending platform in Lanzhou? We need to ensure the delivery rate so that every customer of mine can receive my notice.

I advise you not to look around. There are many scammers on the Internet. Our company cooperates with Lanzhou Lingyun. Cooperation for more than half a year, the delivery rate has been very good. Don't look for cheap ones to save money. . Lingyun SMS business is also very dedicated, and can receive their greeting messages every week. And introduce customers and send text messages. . Ha ha. .
