Lansweeper will only send a newsletter when releasing a major upgrade of Lansweeper. E.g. our last newsletter was send for the 6.0.0.48-release. You may have accidentally unsubscribed from our newsletter. To re-register, you can contact sales (https://www.lansweeper.com/contact-sales/).
To be notified of a minor upgrade, you can use the build-in function to automatically check once a week if a new upgrade is available. When this option (which can be found under Configuration\Your Lansweeper License) is checked and Lansweeper finds a new version, you will receive a pop-up screen alerting you of this next time you log on to the Lansweeper console.
