Why eMailGrouper?

Does anyone really need a new way to communicate with their friends, co-workers, book club, or classmates?

No. But, we all need a better way. Instead of joining yet another social media platform, installing a new app, or navigating a clunky and ad-packed website, what if you could just keep using the Inbox and Address Book you already have?

With eMailGrouper you can! If you've ever:

  • Tried to start a Facebook group for your Book Club, only to discover that one of the members doesn't have a Facebook account
  • Communicated with your Board of Directors by scrolling through your Inbox looking for the last message you sent them, hitting "Reply All", deleting the old Subject, typing a new subject, deleting the old Body, typing a new body, making sure your signature gets re-added because you probably deleted it by accident...
  • Set up a group for your fraternity brothers in Outlook (or Gmail, or Apple Mail, or Mutt...), only to discover it isn't accessible from your iPhone (you have noticed this, haven't you? If not, drop what you're doing and go check!)
  • Manually typed 10 addresses into an email to your Thursday night poker group, only to discover that one of the addresses you used was outdated, or (worse yet!) you accidentally invited the Most Annoying Guy in the World and there's no way to uninvite him

Then you're going to love eMailGrouper. With our service, you'll:

  • Sign up for an account in two steps, then name your first group.
  • Add members to your first group right from your Inbox - Mac or PC, Gmail, Outlook, Apple Mail, even right from your iPhone or iPad.
  • Do everything else from your Inbox - add members, remove members, query our system to remind you who the members are, even create New Groups! (We'll walk you through the steps in our Welcome Email)
  • Keep all your groups in sync across all your devices, using the Address Book you already have, with iCloud, Exchange, Google, etc. working behind the scenes. Best of all, your group members never need to sign up for anything. In fact, if they're not paying close attention, they may never notice you've started using eMailGrouper...and that's our goal: super-easy for Group Owners, totally transparent for Group Members.
