  • Easiest way to automate e-mails? (Newbie question)
    If you have Gmail or Gsuite, try GMass - gmass.co. Cheap, easy, and uses your email address, so not spam filtering. Source: over 1 year ago
  • Doesn’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 1 year ago
  • "Closing" isn't in the subject line and "If you want my help launching..." wasn't in the body of the email. How did they do this?
    You can use gmass.co to achieve this with gmail You can use inboxpirates to check how it looks on different email clients. Source: almost 2 years ago
  • Calling all small businesses!
    To send emails you can use Gmass, I preffer GBeast because it allows to send from multiple Gmail and G-Suite accounts and supports proxies to avoid the Google hammer. Source: about 2 years ago
  • What are the best Gmail extensions you've ever used?
    On my end, vocal.email and gmass.co are extensions I use daily :). Source: over 2 years ago
