Gmail has implemented changes that impact the use of gmail.com addresses as senders for third-party services like Site24x7. These changes are scheduled to take effect on February 1, 2024. 

As a result, Site24x7 will no longer utilize Gmail as the sender address for alert emails. This decision is aimed at preventing emails from being quarantined and ensuring the continuous delivery of critical notifications. If you are currently using a gmail.com address as the sender for Site24x7 alerts, please follow the steps outlined in this knowledge base article to update your settings before the deadline.

Similarly, to change your sender email address for Mail Delivery monitors, kindly refer to this help documentation.

It's important to note that if no changes are made by the specified deadline, we will automatically switch to using noreply@site24x7.<domain> beginning on February 1, 2024, to avoid any service interruption. Should you encounter any challenges during this transition or require assistance in updating your email settings, please do not hesitate to reach out to our dedicated support team at support@site24x7.com.

Site24x7 Team
