> Your Google Voice number (xxx) xxx-xxxx will expire in 30 days
Sent by "voice-noreply@google.com".
I used to get emails from them: 2013-08-11 "Your Google Voice number --- has expired", 2021-04-11 "Your Google Voice number --- will expire in 30 days", 2021-11-06 "Your Google Voice number --- will expire in 30 days", 2021-11-30 "Your Google Voice number --- will expire in 7 days"
Nothing about expiring numbers since then. The last contact I had was: "2022-12-14 Notice: Verify your Google Voice forwarding phone --- in the next 30 days"
