  • Doesnโ€™t seem worth it to switch from gmail if this happens
    I did some tests today at gmass.co using my [xxx@pm.me](mailto:xxx@pm.me) email address and any of the many @pm.me emails I use go directly to the Primary Inbox on the tests. Whenever I use one of my authorized domains, even sending it from within protonmail.com, it ends up in Spam. Source: over 3 years ago
