I use google calendar, but send emails from an email alias there. When I send calendar invites, it says it's from my Google email address. Is there a way to get this sent "from" the alias email address?
Unfortunately, Google Calendar doesn't have a way to edit the email invitations are sent from. The invite will only come from the primary email address.
It's a feature that has been requested for years, as I was able to find a thread on the subject. See How to use aliases in Google Calendar?
I always suggest submitting a feature idea through Google Workspace if you have: Feature Idea !
