Google might let users change the email address associated with their account

"Reading through the support page, the way it works is that once every 12 months, Google will allow you to "change" the email address associated with your Google account. In actuality, the process is more like adding a new alias email to your account since your old email address will not be deleted and will remain functional. You still get one email inbox and outbox, but presumably, you will be able to do some filtering based on which email a message was sent to, as well as choose which email to use for outgoing messages. Essentially, Google is giving users a way to associate up to three new email addresses with an existing account and all of its existing data and services."

"That last bit will definitely be interesting to see since many people tend to have more than one Google account registered for various reasons. The most obvious one is two separate email channels. Gmail never condoned such setups officially, but at the same time, the Gmail mail service is one of the few out there to offer server-side email filtering and even conditional forwarding for free. It is a bit buried in legacy settings menus, but it is there. This new potential development can only make a complex email setup even more powerful. Plus, there are some interesting potential implications for things like managed Google accounts on, say, a school Chromebook."

The feature will roll out gradually to users. Once every 12 months, Google will allow users to change the email address associated with a Google account by adding a new alias while leaving the old address active. Each account can add up to three new addresses, spaced a year apart, for a maximum of four associated addresses. Added addresses cannot apparently be deleted. Users retain a single inbox and outbox while gaining the ability to filter incoming mail by recipient address and to select which address to use for outgoing messages. It is unclear whether account merging or Workspace-managed accounts will be supported.
