Send Unlimited Emails in Gmail

  • I've invented a really cool plugin for your Gmail account.
  •  
  • GMass turns your regular Gmail or G Suite account into a powerful email marketing platform. When you send email marketing campaigns from Gmail, you send emails through the world's best servers in terms of deliverability. Prepare for the highest open rates you've ever seen.
  •  
  • For most of our history, email campaigns were restricted to Gmail's sending limits, which are 500 emails/day for @gmail.com accounts and 2,000/day for G Suite accounts.
  •  
  • Now, however, we've invented a way to break Gmail's limits and send unlimited emails from your Gmail account. You do this by connecting your GMass account to an external SMTP service like Sendgrid.
