We have several hundred email lists in GCISD which is a lot but it's easy to find the one you want if you know how.
Start a new email and click on the word TO in the header.
You'll get a pop-up window that will show your own contacts (if you have any saved.) Click on the My Contacts label on the right and change it to Directory.
It will be empty by default.
In the search field, type just a little bit of what you're searching for like the campus initials for example. In the screenshot below we just put gms. When searching for a list, less is more otherwise it would have to be an exact match. After putting your search term, press Return (or Enter.)
You will be shown all the lists that contain gms in the name. When you find the one you want, hover your mouse over it. You will see a box next to the name. Click the box then click Insert.
The list address will be inserted into the To field of your email. You can repeat for other lists if you like.
If you hover your mouse over the list address you will see the members of that list.
