SPMX Mailer is a Windows desktop application used by its operator to send email campaigns from Google accounts they own and control. Instead of composing each message by hand, the app lets the operator connect their own accounts once and send messages on their own behalf through the official Gmail API.
SPMX Mailer is a first-party tool: the person who installs it connects and sends only from their own Google accounts. It is not a service that acts on behalf of other people's accounts.
SPMX Mailer requests only the Gmail send permission, and uses it solely to send messages the operator composes. We never sell or share data obtained through Google APIs, and we do not use it for advertising or to train AI models.
