SocketLabs was founded over 14 years ago to change the way people and businesses use email. And while our technology and services have evolved, our commitment to the people we serve has not. For customers who have used other ESPs or are seeking help for the first time, the SocketLabs experience will be a new one. This is technology, services, support, and analytics, built for you. Unlike other ESPs, at SocketLabs, we treat our customers like we treat our own employees, as real people with unique needs. Get ready to experience the SocketLabs difference.
