We will be undergoing maintenance migrating mail services from mail1.americas1 to a new cloud hosting provider. The maintenance window will begin at 9:00 PM PST on Friday March 1 and last until 5:00 AM PST on Saturday, March 2.
During the maintenance window there might be periods where you are unable to send or receive mail.
Once the maintenance window is complete your mail will flow as normal and you should receive any messages you were sent during the maintenance window.
