EMAIL ADDRESS PRIVACY
You and everyone member of your email group is allocated a substitute email address.
When you email each other, only the substitute email address of the sender is visible in the From and To fields. So, if there is a privacy breach, no ones private email is compromised.
The Technical Stuff - Domain Names
If you want to use your own domain (the bit after the @ sign), you will need to set that up with us. Usually a technical person in your organisation will work with us to sort that out. Alternatively, all your group emails will come from a GroupSend email account… it would look something like email@example.com.
To use your own domain name...
You will need to create a new subdomain and point it at our servers. For example, if your regular domain is @greatbiz.com, your subdomain could be @clients.greatbiz.com, or maybe @events.greatbiz.com.
After that one-off setup, you can start creating email groups and inviting members.
