My wife and I have both used gmail for twenty years - she's been sending me email from her account for years, with my personal domain forwarding to my gmail. But since the Google Domains > Squarespace disaster, the gmail spam filter has lost the plot - it will occasionally spam filter of her from-gmail emails mid thread.

I am certain I have missed critical emails because of this, so trust is gone. I now have to dedicate time each day to going through my gets-an-email-every-two-minutes spam folder. Even though I happily worked there for 16 years, I sadly now find myself in the process of de-Googling.
